Technical Requirements
145.A.1 General
This is a regulation common to the states Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan
and Sri Lanka (here in after referred as Member States) for the Maintenance Organisations.
For the purpose of this Part, the Competent Authority for organisations having their principal
place of business in Bangladesh shall be Civil Aviation Authority of Bangladesh.
For the purpose of this Part, Part-21 shall be for organisations approved by Civil Aviation
Authority of Bangladesh shall be ANO (AW) Chapter A.1.
For the purpose of this Part, Competent Authority Form 1 shall be for organisations approved by
Civil Aviation Authority, Bangladesh shall be CAAB Form 1.
For the purpose of this Part, Competent Authority Form 2 shall be for organisations approved by
Civil Aviation Authority, Bangladesh shall be CAAB Form 2.
For the purpose of this Part, Competent Authority Form 3 shall be for organisations approved by
Civil Aviation Authority, Bangladesh shall be CAAB Form 3.
For the purpose of this Part, Competent Authority Form 4 shall be for organisations approved by
Civil Aviation Authority, Bangladesh shall be CAAB Form 4.
Within the scope of this regulation, the following definitions shall apply:
(a) ‗Aircraft‘ means any machine that can derive support in the atmosphere from the reactions of
the air other than reactions of the air against the earth's surface;
(b) ‗Certifying staff‘ means personnel responsible for the release of an aircraft or a component
after maintenance;
(d) ‗large aircraft‘ means an aircraft, classified as an aeroplane with a maximum take-off mass of
more than 5 700 kg, or a multi-engine helicopter;
(e) ‗large aeroplane‘ means an aeroplane of more than 5700 kg (12500 pounds) maximum
certificated take-off weight. The category ‗Large Aeroplane‘ does not include the commuter
aeroplane category
(f) ―Commuter category aeroplane‖ means a propeller-driven twin-engined aeroplane that has a
seating configuration, excluding the pilot seat(s) of nineteen of fewer and a maximum
certified take off weight of 8618 kg (19000 lb).
(g) ‗Maintenance‘ means any one or combination of overhaul, repair, inspection, replacement,
modification or defect rectification of an aircraft or component, with the exception of pre-
flight inspection;
(h) ‗Organisation‘ means a natural person, a legal person or part of a legal person. Such an
organisation may hold more than one Part 145 approval;
(i) ‗Pre-flight inspection‘ means the inspection carried out before flight to ensure that the aircraft
is fit for the intended flight;
(j) ―Principle place of business‖ means the head office or the registered office of the undertaking
within which the principle financial functions and operational control of the activities referred
to in this Regulation are exercised.
145.A.5 Applicability
Organisations involved in the maintenance of large aircraft or of aircraft used for commercial air
transport and components intended for fitment thereto, shall be approved in accordance with the
provisions of this Part.
145.A.10 Scope
This Section establishes the requirements to be met by an organisation to qualify for the issue or
continuation of an approval for the maintenance of aircraft and components.
(c) Maintenance tasks falling outside these criteria are considered to be Base Maintenance.
GM 145.A.10 Scope
This Guidance Material (GM) provides guidance on how the smallest organisations satisfy the
intent of Part-145:
2. It is recognised that a Part-145 approval may be required by two quite different types of small
organisations, the first being the light aircraft maintenance hangar, the second being the
component maintenance workshop, e.g. small piston engines, radio equipment, etc.
3. Where only one person is employed (in fact having the certifying function and others), these
organisations approved under Part-145 may use the alternatives provided in point 3.1 limited
to the following:
Class A2 Base and Line maintenance of aeroplanes of 5700 kg and below (piston engines
only).
Class A3 Base and Line maintenance of single-engined helicopters of less than 3175 kg.
Class A4 Aircraft other than A1, A2 and A3
Class B2 Piston engines with maximum output of less than 450 HP.
Class C Components.
Class D1 Non destructive Testing.
3.1 145.A.30 (b): The minimum requirement is for one full-time person who meets the Part-
66 requirements for certifying staff and holds the position of ‗accountable manager,
maintenance engineer and is also certifying staff‘. No other person may issue a certificate
of release to service and therefore if absent, no maintenance may be released during such
absence.
Note: Full-time for the purpose of Part-145 means not less than 35 hrs per week
except during vacation periods.
3.1.2 145.A.35. In the case of an approval based on one person using a subcontracted
quality monitoring arrangement, the requirement for a record of certifying staff is
satisfied by the submission to and acceptance by the Competent Authority of the
CAAB Form 4. With only one person the requirement for a separate record of
authorisation is unnecessary because the CAAB Form 3 approval schedule defines
the authorisation. An appropriate statement, to reflect this situation, should be
included in the exposition.
4.1 145.A.30 (b): The normal minimum requirement is for the employment on a full-time
basis of two persons who meet the Competent Authority‘s requirements for certifying
staff, whereby one holds the position of ‗maintenance engineer‘ and the other holds the
position of ‗quality audit engineer‘.
Either person can assume the responsibilities of the accountable manager providing that
they can comply in full with the applicable elements of 145.A.30(a), but the
‗maintenance engineer‘ should be the certifying person to retain the independence of the
‗quality audit engineer‘ to carry out audits. Nothing prevents either engineer from
undertaking maintenance tasks providing that the ‗maintenance engineer‘ issues the
certificate of release to service.
The ‗quality audit engineer‘ should have similar qualifications and status to the
‗maintenance engineer‘ for reasons of credibility, unless he/she has a proven track-record
in aircraft quality assurance, in which case some reduction in the extent of maintenance
qualifications may be permitted.
In cases where the Competent Authority agrees that it is not practical for the organisation
to nominate a post holder for the quality monitoring function, this function may be
contracted in accordance to paragraph 3.1.1.
145.A.15 Application
An application for the issue or change of an approval shall be made to the Competent Authority in
a form and manner established by such Authority.
The following table identifies the ATA Specification 2200 chapter for the category C component
rating. If the maintenance manual (or equivalent document) does not follow the ATA Chapters,
the corresponding subjects still apply to the applicable C rating.
(a) Facilities are provided appropriate for all planned work, ensuring in particular, protection
from the weather elements. Specialised workshops and bays are segregated as appropriate, to
ensure that environmental and work area contamination is unlikely to occur.
1. For base maintenance of aircraft, aircraft hangars are both available and large enough to
accommodate aircraft on planned base maintenance;
2. For component maintenance, component workshops are large enough to accommodate the
components on planned maintenance.
(b) Office accommodation is provided for the management of the planned work referred to in
paragraph (a), and certifying staff so that they can carry out their designated tasks in a manner
that contributes to good aircraft maintenance standards.
(c) The working environment including aircraft hangars, component workshops and office
accommodation is appropriate for the task carried out and in particular special requirements
observed. Unless otherwise dictated by the particular task environment, the working
environment must be such that the effectiveness of personnel is not impaired:
1. Temperatures must be maintained such that personnel can carry out required tasks
without undue discomfort.
2. dust and any other airborne contamination are kept to a minimum and not be permitted to
reach a level in the work task area where visible aircraft/component surface
contamination is evident. Where dust/other airborne contamination results in visible
surface contamination, all susceptible systems are sealed until acceptable conditions are
re-established.
3. lighting is such as to ensure each inspection and maintenance task can be carried out in
an effective manner.
4. noise shall not distract personnel from carrying out inspection tasks. Where it is
impractical to control the noise source, such personnel are provided with the necessary
personal equipment to stop excessive noise causing distraction during inspection tasks.
6. the working environment for line maintenance is such that the particular maintenance or
inspection task can be carried out without undue distraction. Therefore where the
working environment deteriorates to an unacceptable level in respect of temperature,
moisture, hail, ice, snow, wind, light, dust/other airborne contamination, the particular
maintenance or inspection tasks must be suspended until satisfactory conditions are re-
established.
(d) Secure storage facilities are provided for components, equipment, tools and material. Storage
conditions ensure segregation of serviceable components and material from unserviceable
aircraft components, material, equipment and tools. The conditions of storage are in
accordance with the manufacturer's instructions to prevent deterioration and damage of stored
items. Access to storage facilities is restricted to authorised personnel.
2. Protection from the weather elements relates to the normal prevailing local weather elements
that are expected throughout any twelve-month period. Aircraft hangar and component
workshop structures should prevent the ingress of rain, hail, ice, snow, wind and dust etc.
Aircraft hangar and component workshop floors should be sealed to minimise dust
generation.
3. For line maintenance of aircraft, hangars are not essential but it is recommended that access
to hangar accommodation be demonstrated for usage during inclement weather for minor
scheduled work and lengthy defect rectification.
4. Aircraft maintenance staff should be provided with an area where they may study
maintenance instructions and complete maintenance records in a proper manner.
In addition, as part of the office accommodation, aircraft maintenance staff should be provided
with an area where they may study maintenance instructions and complete maintenance records in
a proper manner.
2. Storage racks should be strong enough to hold aircraft components and provide sufficient
support for large aircraft components such that the component is not distorted during storage.
3. All aircraft components, wherever practicable, should remain packaged in protective material
to minimise damage and corrosion during storage.
2. establish and promote the safety and quality policy specified in 145.A.65(a).
(b) The organisation shall nominate a person or group of persons, whose responsibilities include
ensuring that the organisation complies with this Part. Such person(s) shall ultimately be
responsible to the accountable manager.
1. The person or persons nominated shall represent the maintenance management structure
of the organisation and be responsible for all functions specified in this Part.
2. The person or persons nominated shall be identified and their credentials submitted in a
form and manner established by the Competent Authority.
4. Procedures shall make clear who deputises for any particular person in the case of
lengthy absence of the said person.
(c) The accountable manager under paragraph (a) shall appoint a person with responsibility for
monitoring the quality system, including the associated feedback system as required by
145.A.65(c). The appointed person shall have direct access to the accountable manager to
ensure that the accountable manager is kept properly informed on quality and compliance
matters.
(d) The organisation shall have a maintenance man-hour plan showing that the organisation has
sufficient staff to plan, perform, supervise, inspect and quality monitor the organisation in
accordance with the approval. In addition the organisation shall have a procedure to reassess
work intended to be carried out when actual staff availability is less than the planned staffing
level for any particular work shift or period.
(e) The organisation shall establish and control the competence of personnel involved in any
maintenance, management and/or quality audits in accordance with a procedure and to a
standard agreed by the Competent Authority. In addition to the necessary expertise related to
the job function, competence must include an understanding of the application of human
factors and human performance issues appropriate to that person's function in the
organisation.
"Human factors" means principles which apply to aeronautical design, certification, training,
operations and maintenance and which seek safe interface between the human and other
system components by proper consideration of human performance.
"Human performance" means human capabilities and limitations which have an impact on the
safety and efficiency of aeronautical operations.
(f) The organisation shall ensure that personnel who carry out and/or control a continued
airworthiness non-destructive test of aircraft structures and/or components are appropriately
qualified for the particular non-destructive test in accordance with the European or equivalent
Issue-2 March, 2017 Civil Aviation Authority, Bangladesh 1-9
ANO (AW) Part-145 Approved Maintenance Organization
Chapter 1: Regulations & Acceptable Means of Compliance (Section A)
Standard recognised by the Competent Authority. Personnel who carry out any other
specialised task shall be appropriately qualified in accordance with officially recognised
Standards. By derogation to this paragraph those personnel specified in paragraphs (g) and
(h)(1) and (h)(2), qualified in category B1 or B3 in accordance with Part-66 may carry out
and/or control colour contrast dye penetrant tests.
(g) Any organisation maintaining aircraft, except where stated otherwise in point (j), shall in the
case of aircraft line maintenance, have appropriate aircraft rated certifying staff qualified as
category B1, B2, B3, as appropriate, in accordance with Part-66 and point 145.A.35.
In addition such organisations may also use appropriately task trained certifying staff holding
the privileges described in points 66.A.20(a)(1) and 66.A.20(a)(3)(ii) and qualified in
accordance with Part-66 and part 145.A.35 to carry out minor scheduled line maintenance
and simple defect rectification. The availability of such certifying staff shall not replace the
need for category B1, B2, B3 certifying staff, as appropriate.
(h) Any organisation maintaining aircraft, except where stated otherwise in paragraph (j) shall:
1. In the case of base maintenance of large aircraft, have appropriate aircraft type rated
certifying staff qualified as category C in accordance with Part-66 and 145.A.35. In
addition the organisation shall have sufficient aircraft type rated staff qualified as
category B1, B2 as appropriate in accordance with Part-66 and 145.A.35 to support the
category C certifying staff.
(i) B1 and B2 support staff shall ensure that all relevant tasks or inspections have been
carried out to the required standard before the category C certifying staff issues the
certificate of release to service.
(ii) The organisation shall maintain a register of any such B1 and B2 support staff.
(iii) The category C certifying staff shall ensure that compliance with paragraph (i) has
been met and that all work required by the customer has been accomplished during
the particular base maintenance check or work package, and shall also assess the
impact of any work not carried out with a view to either requiring its
accomplishment or agreeing with the operator to defer such work to another
specified check or time limit.
2. in the case of base maintenance of aircraft other than large aircraft have either:
(i) appropriate aircraft rated certifying staff qualified as category B1, B2, B3, as
appropriate, in accordance with Part-66 and point 145.A.35 or,
(ii) appropriate aircraft rated certifying staff qualified in category C assisted by support
staff as specified in point 145.A.35(a)(i).
(i) Component certifying staff shall comply with Part-66.
(j) By derogation to paragraphs (g) and (h), in relation to the obligation to comply with Part-66,
the organisation may use certifying staff qualified in accordance with the following
provisions:
1. For organisation facilities located outside the Competent Authority territory certifying
staff may be qualified in accordance with the national aviation regulations of the State in
2. For line maintenance carried out at a line station of an organisation which is located
outside Competent Authority territory, the certifying staff may be qualified in
accordance with the national aviation regulations of the State in which the line station is
based, subject to the conditions specified in Appendix IV of to this Part.
3. For a repetitive pre-flight airworthiness directive which specifically states that the flight
crew may carry out such airworthiness directive, the organisation may issue a limited
certification authorisation to the aircraft commander and/or the flight engineer on the
basis of the flight crew licence held. However, the organisation shall ensure that
sufficient practical training has been carried out to ensure that such aircraft commander
or flight engineer can accomplish the airworthiness directive to the required standard.
4. In the case of aircraft operating away from a supported location the organisation may
issue a limited certification authorisation to the commander and/or the flight engineer on
the basis of the flight crew licence held subject to being satisfied that sufficient practical
training has been carried out to ensure that the commander or flight engineer can
accomplish the specified task to the required standard. The provisions of this paragraph
shall be detailed in an exposition procedure.
5. In the following unforeseen cases, where an aircraft is grounded at a location other than
the main base where no appropriate certifying staff is available, the organisation
contracted to provide maintenance support may issue a one-off certification
authorisation:
(i) to one of its employees holding equivalent type authorisations on aircraft of similar
technology, construction and systems; or
(ii) to any person with not less than five years maintenance experience and holding a
valid ICAO aircraft maintenance licence rated for the aircraft type requiring
certification provided there is no organisation appropriately approved under this
Part at that location and the contracted organisation obtains and holds on file
evidence of the experience and the licence of that person.
All such cases as specified in this subparagraph shall be reported to the Competent
Authority within seven days of the issuance of such certification authorisation. The
organisation issuing the one-off authorisation shall ensure that any such maintenance that
could affect flight safety is re-checked by an appropriately approved organisation.
2. The organisation should have, dependent upon the extent of approval, a base maintenance
manager, a line maintenance manager, a workshop manager and a quality manager, all of
whom should report to the accountable manager except in small Part-145 organisation where
any one manager may also be the accountable manager, as determined by the Competent
Authority he/she may also be the line maintenance manager or the workshop manager.
3. The base maintenance manager is responsible for ensuring that all maintenance required to be
carried out in the hangar, plus any defect rectification carried out during base maintenance, is
carried out to the design and quality standards specified in 145.A.65 (b). The base
maintenance manager is also responsible for any corrective action resulting from the quality
compliance monitoring of 145.A.65(c).
4. The line maintenance manager is responsible for ensuring that all maintenance required to be
carried out on the line including line defect rectification is carried out to the standards
specified in 145.A.65(b) and also responsible for any corrective action resulting from the
quality compliance monitoring of 145.A.65(c).
5. The workshop manager is responsible for ensuring that all work on aircraft components is
carried out to the standards specified in 145.A.65(b) and also responsible for any corrective
action resulting from the quality compliance monitoring of 145.A.65(c).
7. Notwithstanding the example sub-paragraphs 2 - 6 titles, the organisation may adopt any title
for the foregoing managerial positions but should identify to the Competent Authority the
titles and persons chosen to carry out these functions.
8. Where an organisation chooses to appoint managers for all or any combination of the
identified Part-145 functions because of the size of the undertaking, it is necessary that these
managers report ultimately through either the base maintenance manager or line maintenance
manager or workshop manager or quality manager, as appropriate, to the accountable
manager.
NOTE: Certifying staff may report to any of the managers specified depending upon which
type of control the approved maintenance organisation uses (for example licensed
engineers/independent inspection/dual function supervisors etc.) so long as the quality
compliance monitoring staff specified in 145.A.65(c)(1) remain independent.
AMC 1 145.A.30(e)
Competence should be defined as a measurable skill or standard of performance, knowledge and
understanding, taking into consideration attitude and behaviour.
The referenced procedure requires amongst others that planners, mechanics, specialised services
staff, supervisors, certifying staff and support staff, whether employed or contracted, are assessed
for competence before unsupervised work commences and competence is controlled on a
continuous basis.
Issue-2 March, 2017 Civil Aviation Authority, Bangladesh 1-13
ANO (AW) Part-145 Approved Maintenance Organization
Chapter 1: Regulations & Acceptable Means of Compliance (Section A)
Validation of the above could include a confirmation check with the organisation(s) that issued
such document(s). For that purpose, experience/training may be recorded in a document such as a
log book or based on the suggested template in GM 3 to 145.A.30(e).
This should include copies of all documents that attest to qualification, such as the licence and/or
any authorisation held, as applicable.
For a proper competence assessment of its personnel, the organisation should consider that:
1. In accordance with the job function, adequate initial and recurrent training should be
provided and recorded to ensure continued competence so that it is maintained throughout the
duration of employment/contract.
2. All staff should be able to demonstrate knowledge of and compliance with the maintenance
organisation procedures, as applicable to their duties.
3. All staff should be able to demonstrate an understanding of human factors and human
performance issues in relation with their job function and be trained as per AMC 2 145.A.30
(e).
4. To assist in the assessment of competence and to establish the training needs analysis, job
descriptions are recommended for each job function in the organisation. Job descriptions
should contain sufficient criteria to enable the required competence assessment.
5. Criteria should allow the assessment to establish that, among others (titles might be different
in each organisation):
— Managers are able to properly manage the work output, processes, resources and
priorities described in their assigned duties and responsibilities in a safe compliant
manner in accordance with regulations and organisation procedures.
— Planners are able to interpret maintenance requirements into maintenance tasks, and
have an understanding that they have no authority to deviate from the maintenance data.
— Supervisors are able to ensure that all required maintenance tasks are carried out and,
where not completed or where it is evident that a particular maintenance task cannot be
carried out to the maintenance data, then such problems will be reported to the
145.A.30(c) person for appropriate action. In addition, for those supervisors, who also
— Mechanics are able to carry out maintenance tasks to any standard specified in the
maintenance data and will notify supervisors of defects or mistakes requiring
rectification to re-establish required maintenance standards.
— Specialized services staff are able to carry out specialized maintenance tasks to the
standard specified in the maintenance data. They should be able to communicate with
supervisors and report accurately when necessary.
— Support staff are able to determine that relevant tasks or inspections have been carried
out to the required standard.
— Certifying staff are able to determine when the aircraft or aircraft component is ready to
release to service and when it should not be released to service.
— Quality audit staff are able to monitor compliance with Part-145 identifying
non-compliance in an effective and timely manner so that the organization may remain
in compliance with Part-145.
Competence assessment should be based upon the procedure specified in GM 2 to 145.A.30(e).
AMC 2 145.A.30(e)
In respect to the understanding of the application of human factors and human performance
issues, all maintenance organization personnel should have received an initial and continuation
human factors training. This should concern to a minimum:
— Post-holders, managers, supervisors;
— Certifying staff, support staff and mechanics;
— Technical support personnel such as planners, engineers, technical record staff;
— Quality control/assurance staff;
— Specialised services staff;
— Human factors staff/human factors trainers;
— Store department staff, purchasing department staff;
— Ground equipment operators.
1. Initial human factors training should cover all the topics of the training syllabus specified in
GM 145.A.30(e) either as a dedicated course or else integrated within other training. The
syllabus may be adjusted to reflect the particular nature of the organisation. The syllabus
may also be adjusted to meet the particular nature of work for each function within the
organisation. For example:
o small organisations not working in shifts may cover in less depth subjects related to
teamwork and communication;
o planners may cover in more depth the scheduling and planning objective of the
syllabus and in less depth the objective of developing skills for shift working.
All personnel, including personnel being recruited from any other organisation should
receive initial human factors training compliant with the organisation‘s training standards
prior to commencing actual job function, unless their competence assessment justifies that
there is no need for such training. Newly directly employed personnel working under direct
supervision may receive training within 6 months after joining the maintenance
organisation.
2. The purpose of human factors continuation training is primarily to ensure that staff remain
current in terms of human factors and also to collect feedback on human factors issues.
Consideration should be given to the possibility that such training has the involvement of the
quality department. There should be a procedure to ensure that feedback is formally passed
from the trainers to the quality department to initiate action where necessary.
Human factors continuation training should be of an appropriate duration in each two year
period in relation to relevant quality audit findings and other internal/external sources of
information on human errors in maintenance available to the organisation.
4. The human factors training procedures should be specified in the maintenance organization
exposition.
AMC 3 145.A.30(e)
Additional training in fuel tank safety as well as associated inspection standards and maintenance
procedures should be required for maintenance organisations‘ technical personnel, especially
technical personnel involved in the compliance of CDCCL tasks.
AMC 4 145.A.30(e)
Competence assessment should include the verification for the need of additional EWIS training
when relevant.
In the absence of specific Competent Authority ANO (AW) Part-145 guidance, guidance of
EASA AMC 20-22 may be used for EWIS training programme to maintenance organisation
personnel.
3. Notwithstanding the fact that Level 3 personnel may be qualified via EN 4179 or any
standard recognised by the Competent Authority to establish and authorise methods,
techniques, etc., this does not permit such personnel to deviate from methods and techniques
published by the type certificate holder/manufacturer in the form of continued airworthiness
data, such as in non-destructive test manuals or service bulletins, unless the manual or service
bulletin expressly permits such deviation.
4. All examinations should be conducted by personnel or organisations under the control of an
organisation (NDT board for example) recognised by the Competent Authority.
5. Particular non-destructive test means any one or more of the following; Dye penetrant,
magnetic particle, eddy current, ultrasonic and radiographic methods including X ray and
gamma ray.
6. It should be noted that new methods are and will be developed, such as, but not limited to
thermography and shearography, which are not specifically addressed in the standards
recognised by the Competent Authority. Until the time this agreed standard is established,
such methods should be carried out in accordance with the particular equipment
manufacturer‘s recommendations including any training and examination process to ensure
competence of the personnel in the process.
7. Any maintenance organisation approved under Part-145 that carries out NDT should establish
NDT specialist qualification procedures detailed in the exposition and accepted by the
Competent Authority.
8. Boroscoping and other techniques such as delamination coin tapping are non-destructive
inspections rather than non-destructive testing. Notwithstanding such differentiation, the
maintenance organisation should establish an exposition procedure accepted by the
Competent Authority to ensure that personnel who carry out and interpret such inspections
are properly trained and assessed for their competence in the process. Non-destructive
inspections, not being considered as NDT by Part-145 are not listed in Appendix II under
class rating D1.
9. The referenced standards, methods, training and procedures should be specified in the
maintenance organisation exposition.
10. Any such personnel who intend to carry out and/or control a non-destructive test for which
they were not qualified prior to the effective date of Part-145 should qualify for such non-
destructive test in accordance with EN 4179 or a standard recognised as equivalent or
acceptable to the Competent Authority.
11. In this context officially recognised standard means those standards established or published
by an official body whether having legal personality or not, which are widely recognised by
the air transport sector as constituting good practice.
2. Typical tasks permitted after appropriate task training to be carried out by the 66.A.20(a)(1)
and the 66.A.20(a)(3)(ii) personnel for the purpose of these personnel issuing an aircraft
certificate of release to service as specified in 145.A.50 as part of minor scheduled line
maintenance or simple defect rectification are contained in the following list:
(a) Replacement of wheel assemblies.
(e) Replacement of internal and external lights, filaments and flash tubes.
(g) Replacement of passenger and cabin crew seats, seat belts and harnesses.
(j) Simple repairs and replacement of internal compartment doors and placards but
excluding doors forming part of a pressure structure.
(k) Simple repairs and replacement of overhead storage compartment doors and cabin
furnishing items.
(n) Replacement of in-flight entertainment system components other than public address.
(o) Routine lubrication and replenishment of all system fluids and gases.
(p) The de-activation only of sub-systems and aircraft components as permitted by the
operator's minimum equipment list where such de-activation is agreed by the Competent
Authority as a simple task.
(r) Any other task agreed by the Competent Authority as a simple task for a particular
aircraft type. This may include defect deferment when all the following conditions are
met:
In the particular case of helicopters, and in addition to the items above, the following:
(s) removal and installation of Helicopter Emergency Medical Service (HEMS) simple
internal medical equipment.
(t) removal and installation of external cargo provisions (i.e., external hook, mirrors) other
than the hoist.
(u) removal and installation of quick release external cameras and search lights.
(v) removal and installation of emergency float bags, not including the bottles.
(w) removal and installation of external doors fitted with quick release attachments.
(x) removal and installation of snow pads/skid wear shoes/slump protection pads.
3. The requirement of having appropriate aircraft rated certifying staff qualified as category B1,
B2, B3, as appropriate, in the case of aircraft line maintenance does not imply that the
organization must have B1, B2 and B3 personnel at every line station. The MOE should have
a procedure on how to deal with defects requiring B1, B2 or B3 certifying staff.
4. Competent Authority may accept that in the case of aircraft line maintenance an organization
has only B1, B2 or B3 certifying staff, as appropriate, provided that the Competent Authority
is satisfied that the scope of work, as defined in the Maintenance Organization Exposition,
does not need the availability of all B1, B2 and B3 certifying staff. Special attention should
be taken to clearly limit the scope of scheduled and non-scheduled line maintenance (defect
rectification) to only those tasks that can be certified by the available certifying staff
category.
Nevertheless, the organisation may use as support staff (for base maintenance) persons who
already hold certification privileges for line maintenance.
(b) Completion of adequate task training for the specific task on the aircraft. The task
training should be of sufficient duration to ensure that the individual has a thorough
understanding of the task to be completed and will involve training in the use of
associated maintenance data.
The above procedures should be specified in the maintenance organisation exposition and be
accepted by the Competent Authority.
2.(i) Typical tasks that may be certified and/or carried out by the commander holding an ATPL or
CPL are minor maintenance or simple checks included in the following list:
(c) Role changes e.g. stretcher fit, dual controls, FLIR, doors, photographic equipment etc.
(e) Any check / replacement involving simple techniques consistent with this AMC and as
agreed by the Competent Authority.
2.(ii) Holders of a valid Flight engineers licence meeting the Competent Authority Flight Crew
Licensing System on the aircraft type may only exercise this limited certification
authorisation privilege when performing the duties of a flight engineer.
In addition to paragraph 2(i)(a) to (e) other typical minor maintenance or simple defect
rectification tasks that may be carried out are included in the following list:
(e) Replacement of passenger and cabin crew seats, seat belts and harnesses.
(f) Simple replacement of overhead storage compartment doors and cabin furnishing items.
(i) Replacement of in-flight entertainment system components other than public address.
(j) The de-activation only of sub-systems and aircraft components as permitted by the
operator's minimum equipment list where such de-activation is agreed by the Competent
Authority as a simple task.
(k) Re-setting of tripped circuit breakers under the guidance of maintenance control.
(l) Any other task agreed by the Competent Authority as a simple task for a particular
aircraft type.
3. The authorisation should have a finite life of twelve months subject to satisfactory re-current
training on the applicable aircraft type.
2. A one-off authorisation should only be considered for issue by the quality department of the
contracted organisation after it has made a reasoned judgement that such a requirement is
appropriate under the circumstances and at the same time maintaining the required
airworthiness standards. The organisation‘s quality department will need to assess each
situation individually prior to the issuance of a one-off authorisation.
3. A one-off authorisation should not be issued where the level of certification required could
exceed the knowledge and experience level of the person it is issued to. In all cases, due
consideration should be given to the complexity of the work involved and the availability of
required tooling and/or test equipment needed to complete the work.
1. Flight crew should communicate full details of the defect to the operator‘s supporting
maintenance organisation. If necessary, the supporting maintenance organisation will then
request the use of a one-off authorisation from the quality department.
2. When issuing a one-off authorisation, the quality department of the organisation should verify
that:
(a) Full technical details relating to the work required to be carried out have been established
and passed on to the certifying staff.
(b) The organisation has an approved procedure in place for coordinating and controlling the
total maintenance activity undertaken at the location under the authority of the one-off
authorisation.

ANO (AW) Part-145 Approved Maintenance Organization
Chapter 1: Regulations & Acceptable Means of Compliance (Section A)
(c) The person to whom a one-off authorisation is issued has been provided with all the
necessary information and guidance relating to maintenance data and any special
technical instructions associated with the specific task undertaken. A detailed step by
step worksheet has been defined by the organisation, communicated to the one-off
authorisation holder.
(d) The person holds authorisations of equivalent level and scope on other aircraft type of
similar technology, construction and systems.
3. The one-off authorisation holder should sign off the detailed step by step worksheet when
completing the work steps. The completed tasks should be verified by visual examination
and/or normal system operation upon return to an appropriately approved Part-145
maintenance facility.
The maintenance organisation may combine, divide, change the order of any subject of the
syllabus to suit its own needs, as long as all subjects are covered to a level of detail appropriate to
the organisation and its personnel.
Some of the topics may be covered in separate training (health and safety, management,
supervisory skills, etc.) in which case duplication of training is not necessary.
Where possible, practical illustrations and examples should be used, especially accident and
incident reports.
Topics should be related to existing legislation, where relevant. Topics should be related to
existing guidance/advisory material, where relevant (e.g. ICAO HF Digests and Training
Manual).
Topics should be related to maintenance engineering where possible; too much unrelated theory
should be avoided.

Advisory note: A copy of the present credential will be kept for at least 3 years from its issuance by
the maintenance organisation.
(i) ‗Support staff‘ means those staff holding a Part-66 aircraft maintenance licence in
category B1, B2 and/or B3 with the appropriate aircraft ratings, working in a base
maintenance environment while not necessarily holding certification privileges.
(ii) ‗Relevant aircraft and/or components‘, means those aircraft or components specified in
the particular certification authorisation.
(iii) ‗Certification authorisation‘ means the authorisation issued to certifying staff by the
organisation and which specifies the fact that they may sign certificates of release to
service within the limitations stated in such authorisation on behalf of the approved
organisation.
(b) Excepting those cases listed in 145.A.30(j) and 66.A.20(a)3(ii) the organisation may only
issue a certification authorisation to certifying staff in relation to the basic categories or
subcategories and any type rating listed on the aircraft maintenance licence as required by
Part-66, subject to the licence remaining valid throughout the validity period of the
authorisation and the certifying staff remaining in compliance with Part-66.
(c) The organisation shall ensure that all certifying staff and support staff are involved in at least
six months of actual relevant aircraft or component maintenance experience in any
consecutive two year period.
For the purpose of this paragraph "involved in actual relevant aircraft or component
maintenance" means that the person has worked in an aircraft or component maintenance
environment and has either exercised the privileges of the certification authorisation and/or
has actually carried out maintenance on at least some of the aircraft type or aircraft group
systems specified in the particular certification authorisation.
(d) The organisation shall ensure that all certifying staff and support staff receive sufficient
continuation training in each two year period to ensure that such staff have up-to-date
knowledge of relevant technology, organisation procedures and human factor issues.
(e) The organisation shall establish a programme for continuation training for certifying staff and
support staff, including a procedure to ensure compliance with the relevant paragraphs of
145.A.35 as the basis for issuing certification authorisations under this Part to certifying staff,
and a procedure to ensure compliance with Part 66.
(f) Except where any of the unforeseen cases of 145.A.30(j)(5) apply, the organisation shall
assess all prospective certifying staff for their competence, qualification and capability to
carry out their intended certifying duties in accordance with a procedure as specified in the
exposition prior to the issue or re-issue of a certification authorisation under this Part.
(g) When the conditions of paragraphs (a), (b), (d), (f) and, where applicable, paragraph (c) have
been fulfilled by the certifying staff, the organisation shall issue a certification authorisation
that clearly specifies the scope and limits of such authorisation. Continued validity of the
certification authorisation is dependent upon continued compliance with paragraphs (a), (b),
(d), and where applicable, paragraph (c).
(h) The certification authorisation must be in a style that makes its scope clear to the certifying
staff and any official of the Competent Authority who has the responsibility for oversight of
maintained aircraft or component, who may require to examine the authorisation.
(i) The person responsible for the quality system shall also remain responsible on behalf of the
organisation for issuing certification authorisations to certifying staff. Such person may
nominate other persons to actually issue or revoke the certification authorisations in
accordance with a procedure as specified in the exposition.
(j) The organisation shall maintain a record of all certifying staff and support staff, which shall
contain:
1. the details of any aircraft maintenance licence held under Part-66; and
2. all relevant training completed; and
3. the scope of the certification authorisations issued, where relevant; and
4. particulars of staff with limited or one-off certification authorisations.
The organisation shall retain the record for at least three years after the staff referred to in this
paragraph have ceased employment with the organisation or as soon as the authorisation has
been withdrawn. In addition, upon request, the maintenance organisation shall furnish the
staff referred to in this paragraph with a copy of their personal record on leaving the
organisation.
The staff referred to in this paragraph shall be given access on request to their personal
records as detailed above.
(k) The organisation shall provide certifying staff with a copy of their certification authorisation
in either a documented or electronic format.
(l) Certifying staff shall produce their certification authorisation to any authorised person within
24 hours.
(m) The minimum age for certifying staff and support staff is 21 years.
(n) The holder of a category A aircraft maintenance licence may only exercise certification
privileges on a specific aircraft type following the satisfactory completion of the relevant
category A aircraft task training carried out by an organisation appropriately approved in
accordance with Part-145 or Part-147. This training shall include practical hands on training
and theoretical training as appropriate for each task authorised. Satisfactory completion of
training shall be demonstrated by an examination or by workplace assessment carried out by
the organisation.
Issue-2 March, 2017 Civil Aviation Authority, Bangladesh 1-30
ANO (AW) Part-145 Approved Maintenance Organization
Chapter 1: Regulations & Acceptable Means of Compliance (Section A)
(o) The holder of a category B2 aircraft maintenance licence may only exercise the certification
privileges described in point 66.A.20(a)(3)(ii) of Part-66 following the satisfactory
completion of (i) the relevant category A aircraft task training and (ii) six months of
documented practical experience covering the scope of the authorisation that will be issued.
The task training shall include practical hands on training and theoretical training as
appropriate for each task authorised. Satisfactory completion of training shall be
demonstrated by an examination or by workplace assessment. Task training and
examination/assessment shall be carried out by the maintenance organisation issuing the
certifying staff authorisation. The practical experience shall be also obtained within such
maintenance organisation.
2. The sentence ― the organisation shall ensure that certifying staff and support staff have an
adequate understanding of the relevant aircraft and/or components to be maintained together
with the associated organisation procedures‖ means that the person has received training and
has been successfully assessed on:
the type of aircraft or component;
the differences on:
o the particular model/variant;
o the particular configuration.
The organisation should specifically ensure that the individual competencies have been
established with regard to:
relevant knowledge, skills and experience in the product type and configuration to be
maintained, taking into account the differences between the generic aircraft type rating
training that the person received and the specific configuration of the aircraft to be
maintained.
appropriate attitude towards safety and observance of procedures.
knowledge of the associated organisation and operator procedures (i.e. handling and
identification of components, MEL use, Technical Log use, independent checks, etc.).
3. Some special maintenance tasks may require additional specific training and experience,
including but not limited to:
in-depth troubleshooting;
very specific adjustment or test procedures;
rigging;
engine run-up, starting and operating the engines, checking engine performance
characteristics, normal and emergency engine operation, associated safety precautions and
procedures;
extensive structural/system inspection and repair;

Chapter 1: Regulations & Acceptable Means of Compliance (Section A)
3. Continuation training should be of sufficient duration in each 2 year period to meet the intent
of 145.A.35(d) and may be split into a number of separate elements. 145.A.35(d) requires
such training to keep certifying staff updated in terms of relevant technology, procedures and
human factors issues which means it is one part of ensuring quality. Therefore sufficient
duration should be related to relevant quality audit findings and other internal / external
sources of information available to the organisation on human errors in maintenance. This
means that in the case of an organisation that maintains aircraft with few relevant quality
Issue-2 March, 2017 Civil Aviation Authority, Bangladesh 1-32
ANO (AW) Part-145 Approved Maintenance Organization
Chapter 1: Regulations & Acceptable Means of Compliance (Section A)
audit findings, continuation training could be limited to days rather than weeks, whereas a
similar organisation with a number of relevant quality audit findings, such training may take
several weeks. For an organisation that maintains aircraft components, the duration of
continuation training would follow the same philosophy but should be scaled down to reflect
the more limited nature of the activity. For example certifying staff who release hydraulic
pumps may only require a few hours of continuation training whereas those who release
turbine engine may only require a few days of such training. The content of continuation
training should be related to relevant quality audit findings and it is recommended that such
training is reviewed at least once in every 24 month period.
4. The method of training is intended to be a flexible process and could, for example, include a
Part-147 continuation training course, aeronautical college courses, internal short duration
courses, seminars, etc. The elements, general content and length of such training should be
specified in the maintenance organisation exposition unless such training is undertaken by an
organisation approved under Part 147 when such details may be specified under the approval
and cross referenced in the maintenance organisation exposition.
2. The record may be kept in any format but should be controlled by the organisation's quality
department. This does not mean that the quality department should run the record system.
3. Persons authorised to access the system should be maintained at a minimum to ensure that
records cannot be altered in an unauthorised manner or that such confidential records become
accessible to unauthorised persons.
4. The Competent Authority is an authorised person when investigating the records system for
initial and continued approval or when the Competent Authority has cause to doubt the
competence of a particular person.
2. When a B2 licence holder already holds a certifying staff authorisation containing minor
scheduled line maintenance and simple defect rectification for a particular aircraft type, new
tasks relevant to category A can be added to that type without requiring another 6 months of
experience. However, task training (theoretical plus practical hands-on) and
examination/assessment for these additional tasks is still required.
3. When the certifying staff authorisation intends to cover several aircraft types, the experience
may be combined within a single 6-month period.
For the addition of new types to the certifying staff authorisation, another 6 months should
be required unless the aircraft is considered similar per AMC 66.A.20(b)2 to the one already
held.
1. Where the manufacturer specifies a particular tool or equipment, the organisation shall
use that tool or equipment, unless the use of alternative tooling or equipment is agreed by
the Competent Authority via procedures specified in the exposition.
2. Equipment and tools must be permanently available, except in the case of any tool or
equipment that is so infrequently used that its permanent availability is not necessary.
Such cases shall be detailed in an exposition procedure.
3. An organisation approved for base maintenance shall have sufficient aircraft access
equipment and inspection platforms/docking such that the aircraft can be properly
inspected.
(b) The organisation shall ensure that all tools, equipment and particularly test equipment, as
appropriate, are controlled and calibrated according to an officially recognised standard at a
frequency to ensure serviceability and accuracy. Records of such calibrations and traceability
to the standard used shall be kept by the organisation.
3. In this context officially recognised standard means those standards established or published
by an official body whether having legal personality or not, which are widely recognised by
the air transport sector as constituting good practice and by the Competent Authority.
Issue-2 March, 2017 Civil Aviation Authority, Bangladesh 1-35
ANO (AW) Part-145 Approved Maintenance Organization
Chapter 1: Regulations & Acceptable Means of Compliance (Section A)
4. Standard parts used on an aircraft, engine, propeller or other aircraft component when
specified in the manufacturer's illustrated parts catalogue and/or the maintenance data.
5. Material both raw and consumable used in the course of maintenance when the
organisation is satisfied that the material meets the required specification and has
appropriate traceability. All material must be accompanied by documentation clearly
relating to the particular material and containing a conformity to specification statement
plus both the manufacturing and supplier source.
(b) Prior to installation of a component, the organisation shall ensure that the particular
component is eligible to be fitted when different modification and/or airworthiness directive
standards may be applicable.
(c) The organisation may fabricate a restricted range of parts to be used in the course of
undergoing work within its own facilities provided procedures are identified in the
exposition.
(d) Components which have reached their certified life limit or contain a non-repairable defect
shall be classified as unsalvageable and shall not be permitted to re-enter the component
supply system unless certified life limits have been extended or a repair solution has been
approved according to a standard acceptable to the Competent Authority.
(b) a release document issued by an organisation approved under the terms bilateral
agreement signed by the Competent Authority;
2. For acceptance of standard parts, raw material and consumable material, refer to AMC
M.A.501(c) and AMC M.A.501 (d).
The receiving organisation should be satisfied that the component in question is in satisfactory
condition and has been appropriately released to service. In addition, the organisation should
ensure that the component meets the approved data/standard, such as the required design and
modification standard. This may be accomplished by reference to the manufacturer‘s parts
catalogue or other approved data (i.e. Service Bulletin). Care should also be taken in ensuring
compliance with applicable airworthiness directives, the status of any life-limited parts fitted to
the aircraft component as well as Critical Design Configuration Control Limitations.
2. Fabrication, inspection assembly and test should be clearly within the technical and
procedural capability of the organisation.
3. All necessary data to fabricate the part should be approved either by the Competent Authority
or the type certificate (TC) holder or design organisation acceptable to the Competent
Authority or supplemental type certificate (STC) holder.
4. Items fabricated by an organisation approved under Part-145 may only be used by that
organisation in the course of overhaul, maintenance, modifications, or repair of aircraft or
components undergoing work within its own facility. The permission to fabricate does not
constitute approval for manufacture, or to supply externally and the parts do not qualify for
certification on CAAB Form 1. This prohibition also applies to the bulk transfer of surplus
inventory, in that locally fabricated parts are physically segregated and excluded from any
delivery certification.
5. Fabrication of parts, modification kits etc. for onward supply and/or sale may not be
conducted by an organisation approved under Part-145.
6. The data specified in paragraph 3 may include repair procedures involving the fabrication of
parts. Where the data on such parts is sufficient to facilitate fabrication, the parts may be
fabricated by an organisation approved under Part-145. Care should be taken to ensure that
the data include details of part numbering, dimensions, materials, processes, and any special
manufacturing techniques, special raw material specification or/and incoming inspection
requirement and that the approved organisation has the necessary capability. That capability
should be defined by way of exposition content. Where special processes or inspection
procedures are defined in the approved data which are not available at the organisation the
organisation cannot fabricate the part unless the TC/STC-holder gives an approved
alternative.

ANO (AW) Part-145 Approved Maintenance Organization
Chapter 1: Regulations & Acceptable Means of Compliance (Section A)
7. Examples of fabrication under the scope of a Part-145 approval can include but are not
limited to the following:
(a) Fabrication of bushes, sleeves and shims.
(b) Fabrication of secondary structural elements and skin panels.
(c) Fabrication of control cables.
(d) Fabrication of flexible and rigid pipes.
(e) Fabrication of electrical cable looms and assemblies.
(f) Formed or machined sheet metal panels for repairs.
All the above fabricated parts should be in accordance with data provided in overhaul or
repair manuals, modification schemes and service bulletins, drawings or otherwise approved
by the Competent Authority.
Note: It is not acceptable to fabricate any item to pattern unless an engineering drawing of the
item is produced which includes any necessary fabrication processes and which is acceptable
to the Competent Authority.
(a) Components with non-repairable defects, whether visible or not to the naked eye;
(b) Components that do not meet design specifications, and cannot be brought into
conformity with such specifications;
(d) Certified life-limited parts that have reached or exceeded their certified life limits, or
have missing or incomplete records;
(e) Components that cannot be returned to airworthy condition due to exposure to extreme
forces, heat or adverse environment;
(f) Components for which conformity with an applicable airworthiness directive cannot be
accomplished;
(g) Components for which maintenance records and/or traceability to the manufacturer can
not be retrieved.
3. The acceptable standards for the Competent Authority are standards approved either by the
type certificate (TC) holder or design organisations acceptable to the Competent Authority,
or supplemental type certificate (STC) holders as applicable.
In the case of maintenance data provided by an operator or customer, the organisation shall
hold such data when the work is in progress, with the exception of the need to comply with
145.A.55(c).
(b) For the purposes of this Part, applicable maintenance data shall be any of the following:
(c) The organisation shall establish procedures to ensure that if found, any inaccurate, incomplete
or ambiguous procedure, practice, information or maintenance instruction contained in the
maintenance data used by maintenance personnel is recorded and notified to the author of the
maintenance data.
(d) The organisation may only modify maintenance instructions in accordance with a procedure
specified in the maintenance organisation's exposition. With respect to those changes, the
organisation shall demonstrate that they result in equivalent or improved maintenance
standards and shall inform the type-certificate holder of such changes. Maintenance
instructions for the purposes of this paragraph means instructions on how to carry out the
particular maintenance task: they exclude the engineering design of repairs and
modifications.
(e) The organisation shall provide a common work card or worksheet system to be used
throughout relevant parts of the organisation. In addition, the organisation shall either
transcribe accurately the maintenance data contained in paragraphs (b) and (d) onto such
work cards or worksheets or make precise reference to the particular maintenance task or
tasks contained in such maintenance data. Work cards and worksheets may be computer
generated and held on an electronic database subject to both adequate safeguards against
unauthorised alteration and a back-up electronic database which shall be updated within 24
hours of any entry made to the main electronic database. Complex maintenance tasks shall be
transcribed onto the work cards or worksheets and subdivided into clear stages to ensure a
record of the accomplishment of the complete maintenance task.
Where the organisation provides a maintenance service to an aircraft operator who requires
their work card or worksheet system to be used then such work card or worksheet system
may be used. In this case, the organisation shall establish a procedure to ensure correct
completion of the aircraft operators' work cards or worksheets.
(f) The organisation shall ensure that all applicable maintenance data is readily available for use
when required by maintenance personnel.
(g) The organisation shall establish a procedure to ensure that maintenance data it controls is kept
up to date. In the case of operator/customer controlled and provided maintenance data, the
organisation shall be able to show that either it has written confirmation from the
operator/customer that all such maintenance data is up to date or it has work orders specifying
the amendment status of the maintenance data to be used or it can show that it is on the
operator/customer maintenance data amendment list.
6. An organisation only approved in class rating category D – Specialised services, should hold
and use all applicable specialised service(s) process specifications.
Important Note: Critical Design Configuration Control Limitations (CDCCL) are airworthiness
limitations. Any modification of the maintenance instructions linked to CDCCL constitutes an
aircraft modification that should be approved in accordance with a standard acceptable to the
Competent Authority.
2. Relevant parts of the organisation means with regard to aircraft base maintenance, aircraft
line maintenance, engine workshops, mechanical workshops and avionic workshops.
Therefore, engine workshops for example should have a common system throughout such
engine workshops that may be different to that in the aircraft base maintenance.
3. The work cards should differentiate and specify, when relevant, disassembly,
accomplishment of task, reassembly and testing. In the case of a lengthy maintenance task
involving a succession of personnel to complete such a task, it may be necessary to use
supplementary work cards or worksheets to indicate what was actually accomplished by each
individual person.
2. Where computer systems are used, the number of computer terminals should be sufficient in
relation to the size of the work programme to enable easy access, unless the computer system
can produce paper copies. Where microfilm or microfiche readers/printers are used, a similar
requirement is applicable.
(b) The planning of maintenance tasks, and the organising of shifts, shall take into account
human performance limitations.
(c) When it is required to hand over the continuation or completion of maintenance tasks for
reasons of a shift or personnel changeover, relevant information shall be adequately
communicated between outgoing and incoming personnel.
2. For the purpose of Part-145, the production planning function includes two complementary
elements:
scheduling the maintenance work ahead, to ensure that it will not adversely interfere with
other work as regards the availability of all necessary personnel, tools, equipment,
material, maintenance data and facilities.
during maintenance work, organising maintenance teams and shifts and provide all
necessary support to ensure the completion of maintenance without undue time pressure.
3. When establishing the production planning procedure, consideration should be given to the
following:
logistics,
inventory control,
preparation of work,
hangar availability,
environmental conditions (access, lighting standards and cleanliness),
(b) A certificate of release to service shall be issued before flight at the completion of any
maintenance.
(c) New defects or incomplete maintenance work orders identified during the above maintenance
shall be brought to the attention of the aircraft operator for the specific purpose of obtaining
agreement to rectify such defects or completing the missing elements of the maintenance
work order. In the case where the aircraft operator declines to have such maintenance carried
out under this paragraph, paragraph (e) is applicable.
(d) A certificate of release to service shall be issued at the completion of any maintenance on a
component whilst off the aircraft. The authorised release certificate CAAB Form 1 referred to
in Appendix I of this Part constitutes the component certificate of release to service. When an
organisation maintains a component for its own use, a CAAB Form 1 may not be necessary
depending upon the organisation‘s internal release procedures defined in the exposition.
(e) By derogation to paragraph (a), when the organisation is unable to complete all maintenance
ordered, it may issue a certificate of release to service within the approved aircraft
limitations. The organisation shall enter such fact in the aircraft certificate of release to
service before the issue of such certificate.
(f) By derogation to paragraph (a) and 145.A.42, when an aircraft is grounded at a location other
than the main line station or main maintenance base due to the non-availability of a
component with the appropriate release certificate, it is permissible to temporarily fit a
component without the appropriate release certificate for a maximum of 30 flight hours or
until the aircraft first returns to the main line station or main maintenance base, whichever is
the sooner, subject to the aircraft operator agreement and said component having a suitable
release certificate but otherwise in compliance with all applicable maintenance and
operational requirements. Such components shall be removed by the above prescribed time
limit unless an appropriate release certificate has been obtained in the meantime under
paragraph (a) and 145.A.42.
‗Certifies that the work specified, except as otherwise specified, was carried out in
accordance with Part-145 and in respect to that work the aircraft/aircraft component is
considered ready for release to service‘.
Reference should also be made to the Competent Authority Part-145 approval number.
3. The certificate of release to service should relate to the task specified in the (S)TC holder‘s or
operator‘s instructions or the aircraft maintenance programme which itself may cross-refer to
maintenance data.
4. The date such maintenance was carried out should include when the maintenance took place
relative to any life or overhaul limitation in terms of date/flying hours/cycles/landings etc., as
appropriate.
5. When extensive maintenance has been carried out, it is acceptable for the certificate of
release to service to summarise the maintenance as long as there is a unique cross-reference
to the work package containing full details of maintenance carried out. Dimensional
information should be retained in the work-pack record.
Issue-2 March, 2017 Civil Aviation Authority, Bangladesh 1-45
ANO (AW) Part-145 Approved Maintenance Organization
Chapter 1: Regulations & Acceptable Means of Compliance (Section A)
The certificate is to be used for export/import purposes, as well as for domestic purposes, and
serves as an official certificate for items from the manufacturer/maintenance organisation to users.
It can only be issued by organisations approved by the Competent Authority within the scope of
the approval.
The certificate may be used as a rotable tag by utilising the available space on the reverse side of
the certificate for any additional information and dispatching the item with two copies of the
certificate so that one copy may be eventually returned with the item to the maintenance
organisation. The alternative solution is to use existing rotable tags and also supply a copy of the
certificate.
A certificate should not be issued for any item when it is known that the item is unserviceable
except in the case of an item undergoing a series of maintenance processes at several maintenance
organisations approved under Part-145 and the item needs a certificate for the previous
maintenance process carried out for the next maintenance organisation approved under Part-145
to accept the item for subsequent maintenance processes. In such a case, a clear statement of
limitation should be endorsed in Block 12.
When an organisation maintains a component for use by the same organisation, a CAAB
Form 1 may not be necessary depending upon the organisation‘s internal release procedures
defined in the maintenance organisation exposition.
2. In the case of the issue of a CAAB Form 1 for components in storage before Part-145 and
Part-21 became effective and not released on an CAAB Form 1 or equivalent in accordance
with 145.A.42(a) or removed serviceable from a serviceable aircraft or an aircraft which has
been withdrawn from service the following applies:
2.1. A CAAB Form 1 may be issued for an aircraft component which has been:
Used on an aircraft and removed in a serviceable condition. Examples include leased and
loaned aircraft components.
Removed from aircraft which have been withdrawn from service, or from aircraft which have
been involved in abnormal occurrences such as accidents, incidents, heavy landings or
lightning strikes.
Maintained by an unapproved organisation.
2.2. An appropriately rated maintenance organisation approved under Part-145 may issue a
CAAB Form 1 as detailed in this AMC subparagraph 2.5 to 2.9, as appropriate, in
accordance with procedures detailed in the exposition as approved by the Competent
Authority. The appropriately rated organisation is responsible for ensuring that all
reasonable measures have been taken to ensure that only approved and serviceable
aircraft components are issued a CAAB Form 1 under this paragraph.
2.3. For the purposes of this AMC No 2 only, appropriately rated means an organisation with
an approval class rating for the type of component or for the product in which it may be
installed.
2.4. A CAAB Form 1 issued in accordance with this paragraph 2 should be issued by signing
in block 14b and stating ‗Inspected‘ in block 11. In addition, block 12 should specify:
2.4.1. When the last maintenance was carried out and by whom.
2.4.2. If the component is unused, when the component was manufactured and by whom
with a cross-reference to any original documentation which should be included
with the Form.
2.4.3. A list of all airworthiness directives, repairs and modifications known to have been
incorporated. If no airworthiness directives or repairs or modifications are known
to be incorporated, then this should be so stated.
2.4.4. Detail of life used for service life-limited parts being any combination of fatigue,
overhaul or storage life.
2.4.5. For any aircraft component having its own maintenance history record, reference
to the particular maintenance history record as long as the record contains the
details that would otherwise be required in block 12. The maintenance history
record and acceptance test report or statement, if applicable, should be attached to
the CAAB Form 1.
Note 1: It should be understood that the release of a stored but unused aircraft
component in accordance with this paragraph represents a maintenance release
under Part-145 and not a production release under Part-21. It is not intended to
bypass the production release procedure agreed by the Competent Authority for
parts and subassemblies intended for fitment on the manufacturers‘ own production
line.
Issue-2 March, 2017 Civil Aviation Authority, Bangladesh 1-47
ANO (AW) Part-145 Approved Maintenance Organization
Chapter 1: Regulations & Acceptable Means of Compliance (Section A)
(a) An acceptance test report or statement should be available for all used and
unused aircraft components that are subjected to acceptance testing after
manufacturing or maintenance as appropriate.
(b) The aircraft component should be inspected for compliance with the
manufacturer‘s instructions and limitations for storage and condition including
any requirement for limited storage life, inhibitors, controlled climate and
special storage containers. In addition or in the absence of specific storage
instructions the aircraft component should be inspected for damage, corrosion
and leakage to ensure good condition.
(c) The storage life used of any storage life-limited parts should be established.
(a) The organisation should ensure that the component was removed from the
aircraft by an appropriately qualified person.
(b) The aircraft component may only be deemed serviceable if the last flight
operation with the component fitted revealed no faults on that
component/related system.
(d) The aircraft record should be researched for any unusual events that could
affect the serviceability of the aircraft component such as involvement in
accidents, incidents, heavy landings or lightning strikes. Under no
circumstances may a CAAB Form 1 be issued in accordance with this
paragraph 2.6 if it is suspected that the aircraft component has been subjected
to extremes of stress, temperatures or immersion which could affect its
operation.
(e) A maintenance history record should be available for all used serialised
aircraft components.
2.7. Used aircraft components removed from an aircraft withdrawn from service. Serviceable
aircraft components removed from a Competent Authority registered aircraft withdrawn
from service may be issued with a CAAB Form 1 by a maintenance organisation
approved under Part-145 subject to compliance with this subparagraph.
(a) Aircraft withdrawn from service are sometimes dismantled for spares. This is
considered to be a maintenance activity and should be accomplished under the
control of an organisation approved under Part-145, employing procedures
approved by the Competent Authority.
(b) To be eligible for installation, components removed from such aircraft may be
issued with a CAAB Form 1 by an appropriately rated organisation following a
satisfactory assessment.
(c) As a minimum, the assessment will need to satisfy the standards set out in
paragraphs 2.5 and 2.6 as appropriate. This should, where known, include the
possible need for the alignment of scheduled maintenance that may be necessary to
comply with the maintenance programme applicable to the aircraft on which the
component is to be installed.
(d) Irrespective of whether the aircraft holds a certificate of airworthiness or not, the
organisation responsible for certifying any removed component should ensure that
the manner in which the components were removed and stored are compatible with
the standards required by Part-145.
(e) A structured plan should be formulated to control the aircraft disassembly process.
The disassembly is to be carried out by an appropriately rated organisation under
the supervision of certifying staff who will ensure that the aircraft components are
removed and documented in a structured manner in accordance with the
appropriate maintenance data and disassembly plan.
(f) All recorded aircraft defects should be reviewed and the possible effects these may
have on both normal and standby functions of removed components are to be
considered.
(h) Suitable Part-145 facilities for the removal and storage of removed components are
to be used which include suitable environmental conditions, lighting, access
equipment, aircraft tooling and storage facilities for the work to be undertaken.
While it may be acceptable for components to be removed, given local
environmental conditions, without the benefit of an enclosed facility, subsequent
disassembly (if required) and storage of the components should be in accordance
with the manufacturer‘s recommendations.
2.8. Used aircraft components maintained by organisations not approved in accordance with
Part-145. For used components maintained by a maintenance organisation not approved
under Part-145, due care should be taken before acceptance of such components. In such
cases an appropriately rated maintenance organisation approved under Part-145 should
establish satisfactory conditions by:
(a) dismantling the component for sufficient inspection in accordance with the
appropriate maintenance data;
(b) replacing all service life-limit components when no satisfactory evidence of life
used is available and/or the components are in an unsatisfactory condition;
2.9. Used aircraft components removed from an aircraft involved in an accident or incident.
Such components should only be issued with a CAAB Form 1 when processed in
accordance with paragraph 2.7 and a specific work order including all additional
necessary tests and inspections deemed necessary by the accident or incident. Such a
work order may require input from the TC holder or original manufacturer as
appropriate. This work order should be referenced in block 12.
2. The aircraft operator is responsible for ensuring that all required maintenance has been
carried out before flight and therefore 145.A.50(e) requires such operator to be informed in
the case where full compliance with 145.A.50(a) cannot be achieved within the operator‘s
limitations. If the operator agrees to the deferment of full compliance, then the certificate of
release to service may be issued subject to details of the deferment, including the operator‘s
authority, being endorsed on the certificate.
Note: Whether or not the aircraft operator does have the authority to defer maintenance is an
issue between the aircraft operator and the competent authority of the State of Registry or
State of operator, as appropriate In case of doubt concerning such a decision of the operator,
the approved maintenance organisation should inform Competent Authority on such doubt,
before issuing the certificate of release to service. This will allow the Competent Authority to
investigate the matter as appropriate.
3. The procedure should draw attention to the fact that 145.A.50 (a) does not normally permit
the issue of a certificate of release to service in the case of non-compliance and should state
what action the mechanic, supervisor and certifying staff should take to bring the matter to
the attention of the relevant department or person responsible for technical co-ordination with
the aircraft operator so that the issue may be discussed and resolved with the aircraft operator.
In addition, the appropriate person(s) as specified in 145.A.30(b) should be kept informed in
writing of such possible non-compliance situations and this should be included in the
procedure.
2. Compliance with all other Part-145 and operator requirements means making an appropriate
entry in the aircraft technical log, checking for compliance with type design standards,
modifications, repairs, airworthiness directives, life limitations and condition of the aircraft
component plus information on where, when and why the aircraft was grounded.
(b) The organisation shall provide a copy of each certificate of release to service to the aircraft
operator, together with a copy of any specific repair/modification data used for
repairs/modifications carried out.
(c) The organisation shall retain a copy of all detailed maintenance records and any associated
maintenance data for three years from the date the aircraft or component to which the work
relates was released from the organisation.
1. The records under this paragraph shall be stored in a manner that ensures protection from
damage, alteration and theft.
2. Computer backup discs, tapes etc. shall be stored in a different location from that
containing the working discs, tapes etc., in an environment that ensures they remain in
good condition.
3. Where an organisation approved under this Part terminates its operation, all retained
maintenance records covering the last two years shall be distributed to the last owner or
customer of the respective aircraft or component or shall be stored as specified by the
Competent Authority.
The prime objective is to have secure and easily retrievable records with comprehensive and
legible contents. The aircraft record should contain basic details of all serialised aircraft
components and all other significant aircraft components installed, to ensure traceability to
such installed aircraft component documentation and associated maintenance data as
specified in 145.A.45.
2. Some gas turbine engines are assembled from modules and a true total time in service for a
total engine is not kept. When owners and operators wish to take advantage of the modular
design, then total time in service and maintenance records for each module is to be
maintained. The maintenance records as specified are to be kept with the module and should
show compliance with any mandatory requirements pertaining to that module.
3. Reconstruction of lost or destroyed records can be done by reference to other records which
reflect the time in service, research of records maintained by repair facilities and reference to
records maintained by individual mechanics etc. When these things have been done and the
record is still incomplete, the owner/operator may make a statement in the new record
describing the loss and establishing the time in service based on the research and the best
estimate of time in service. The reconstructed records should be submitted to the Competent
Authority for acceptance.
4. The maintenance record can be either a paper or computer system or any combination of
both.
5. Paper systems should use robust material which can withstand normal handling and filing.
The record should remain legible throughout the required retention period.
6 Computer systems may be used to control maintenance and/or record details of maintenance
work carried out. Computer systems used for maintenance should have at least one backup
system which should be updated at least within 24 hours of any maintenance. Each terminal
is required to contain programme safeguards against the ability of unauthorised personnel to
alter the database.
(b) The organisation shall establish an internal occurrence reporting system as detailed in the
exposition to enable the collection and evaluation of such reports, including the assessment
and extraction of those occurrences to be reported under paragraph (a). This procedure shall
identify adverse trends, corrective actions taken or to be taken by the organisation to address
deficiencies and include evaluation of all known relevant information relating to such
occurrences and a method to circulate the information as necessary.
(c) The organisation shall make such reports in a form and manner established by the Competent
Authority and ensure that they contain all pertinent information about the condition and
evaluation results known to the organisation.
(d) Where the organisation is contracted by a commercial operator to carry out maintenance, the
organisation shall also report to the operator any such condition affecting the operator's
aircraft or component.
(e) The organisation shall produce and submit such reports as soon as practicable but in any case
within 72 hours of the organisation identifying the condition to which the report relates.
2. An occurrence reporting system should enable and encourage free and frank reporting of any
(potentially) safety related occurrence. This will be facilitated by the establishment of a just
culture. An organisation should ensure that personnel are not inappropriately punished for
reporting or co-operating with occurrence investigations.
3. The internal reporting process should be closed-loop, ensuring that actions are taken
internally to address safety hazards.
4. Feedback to reportees, both on an individual and more general basis, is important to ensure
their continued support for the scheme.
- During routine inspection: Damage found to number 4 engine inlet cowl acoustic lining
- During routine inspection: Rivets found loose on vertical stabiliser
- Found during after flight inspection: Excessive play in tail rotor blade pitch link bearing
at the attachment to the tail rotor blade horn due to bearing migration.
(iii) Date and time relative to any life or overhaul limitation in terms of flying
hours/cycles/landings etc. as appropriate.
(v) Any other relevant information found during the evaluation or rectification of the condition.
145.A.65 Safety and quality policy, maintenance procedures and quality system
(a) The organisation shall establish a safety and quality policy for the organisation to be included
in the exposition under 145.A.70.
(b) The organisation shall establish procedures agreed by the Competent Authority taking into
account human factors and human performance to ensure good maintenance practices and
compliance with this Part which shall include a clear work order or contract such that aircraft
and components may be released to service in accordance with point 145.A.50.
1. The maintenance procedures under this paragraph apply to points 145.A.25 to 145.A.95.
3. With regard to aircraft line and base maintenance, the organisation shall establish
procedures to minimise the risk of multiple errors and capture errors on critical systems,
and to ensure that no person is required to carry out and inspect in relation to a
maintenance task involving some element of disassembly/ reassembly of several
components of the same type fitted to more than one system on the same aircraft during a
particular maintenance check. However, when only one person is available to carry out
these tasks then the organisation‘s work card or worksheet shall include an additional
stage for re-inspection of the work by this person after completion of all the same tasks.
(c) The organisation shall establish a quality system that includes the following:
(d) The organization shall establish a Safety Management System (SMS) that:
(ii) Assesses the impact of these safety hazards and mitigates risks;
(iii) Ensures that remedial action necessary to maintain an acceptable level of safety is
implemented;
(iv) Provides for continuous monitoring and regular assessment of the safety level
achieved; and
(2) Shall meet the requirements contained in Appendix V to this Part; and
AMC 145.A.65(a) Safety and quality policy, maintenance procedures and quality system
The safety and quality policy should as a minimum include a statement committing the
organisation to:
Recognise that compliance with procedures, quality standards, safety standards and
regulations is the duty of all personnel.
Recognise the need for all personnel to cooperate with the quality auditors.
AMC 145.A.65(b) Safety and quality policy, maintenance procedures and quality system
1. Maintenance procedures should be held current such that they reflect best practice within the
organisation. It is the responsibility of all organisation‘s employees to report any differences
via their organisation‘s internal occurrence reporting mechanisms.
2. All procedures, and changes to those procedures, should be verified and validated before use
where practicable.
3. All technical procedures should be designed and presented in accordance with good human
factors principles.
AMC 145.A.65(b)(2) Safety and quality policy, maintenance procedures and quality system
Specialised services include any specialised activity, such as, but not limited to non-destructive
testing requiring particular skills and/or qualification. 145.A.30 (f) covers the qualification of
personnel but, in addition, there is a need to establish maintenance procedures that cover the
control of any specialised process.
AMC 145.A.65(b)(3) Safety and quality policy, maintenance procedures and quality system
1. The purpose of this procedure is to minimise the rare possibility of an error being repeated
whereby the identical aircraft components are not reassembled thereby compromising more
than one system. One example is the remote possibility of failure to reinstall engine gearbox
access covers or oil filler caps on all engines of a multi-engined aircraft resulting in major oil
loss from all engines.
Another example is the case of removal and refitment of oil filler caps, which should require
a re-inspection of all oil filler caps after the last oil filler cap has supposedly been refitted.
2. Procedures should be established to detect and rectify maintenance errors that could, as
minimum, result in a failure, malfunction, or defect endangering the safe operation of the
aircraft if not performed properly. The procedure should identify the method for capturing
errors, and the maintenance tasks or processes concerned.
In order to determine the work items to be considered, the following maintenance tasks
should primarily be reviewed to assess their impact on safety:
3. In order to prevent omissions, every maintenance task or group of tasks should be signed-off.
To ensure the task or group of tasks is completed it should only be signed-off after
completion. Work by unauthorised personnel (i.e. temporary staff, trainee,..) should be
checked by authorised personnel before they sign-off. The grouping of tasks for the purpose
of signing-off should allow critical steps to be clearly identified.
4. The maintenance organisation should ensure that when carrying out a modification, repair or
maintenance, Critical Design Configuration Control Limitations are not compromised; this
will require the development of appropriate procedures where necessary by the maintenance
organisation. The maintenance organisation should pay particular attention to possible
adverse effects of any wiring change to the aircraft, even a change not specifically associated
with the fuel tank system. For example, it should be common practice to identify segregation
of fuel gauging system wiring as a Critical Design Configuration Control Limitation.
Maintenance organisations can prevent adverse effects associated with wiring changes by
standardising maintenance practices through training, rather than by periodic inspection.
Training should be provided to end indiscriminate routing and splicing of wire and to provide
comprehensive knowledge of critical design features of fuel tank systems that would be
controlled by a Critical Design Configuration Control Limitation.
The maintenance of ignition prevention features is necessary for the inherent safety and
reliability of an aircraft‘s fuel tank system. The aircraft cannot be operated indefinitely with
the failure of an ignition prevention feature. The failure will have a direct adverse effect on
Issue-2 March, 2017 Civil Aviation Authority, Bangladesh 1-58
ANO (AW) Part-145 Approved Maintenance Organization
Chapter 1: Regulations & Acceptable Means of Compliance (Section A)
operational safety. It could prevent the continued safe flight and landing of the aircraft or
cause serious or fatal injury to the occupants. The fuel system review required will identify
ignition prevention features of the design. The failure of any of these features may not
immediately result in an unsafe condition, but it may warrant certain maintenance to support
continued airworthiness.
AMC 145.A.65(c)(1) Safety and quality policy, maintenance procedures and quality system
1. The primary objectives of the quality system are to enable the organisation to ensure that it
can deliver a safe product and that organisation remains in compliance with the requirements.
3. The independent audit is an objective process of routine sample checks of all aspects of the
organisation‘s ability to carry out all maintenance to the required standards and includes some
product sampling as this is the end result of the maintenance process. It represents an
objective overview of the complete maintenance related activities and is intended to
complement the 145.A.50 (a) requirement for certifying staff to be satisfied that all required
maintenance has been properly carried out before issue of the certificate of release to service.
Independent audits should include a percentage of random audits carried out on a sample
basis when maintenance is being carried out. This means some audits during the night for
those organisations that work at night.
4. Except as specified in sub-paragraphs 7 and 9, the independent audit should ensure that all
aspects of Part-145 compliance are checked every 12 months and may be carried out as a
complete single exercise or subdivided over the 12-month period in accordance with a
scheduled plan. The independent audit does not require each procedure to be checked against
each product line when it can be shown that the particular procedure is common to more than
one product line and the procedure has been checked every 12 months without resultant
findings. Where findings have been identified, the particular procedure should be rechecked
against other product lines until the findings have been rectified after which the independent
audit procedure may revert back to 12 monthly for the particular procedure.
5. Except as specified otherwise in subparagraphs 7, the independent audit should sample check
one product on each product line every 12 months as a demonstration of the effectiveness of
maintenance procedures compliance. It is recommended that procedures and product audits
be combined by selecting a specific product example, such as an aircraft or engine or
instrument and sample checking all the procedures and requirements associated with the
specific product example to ensure that the end result should be an airworthy product.
For the purpose of the independent audit, a product line includes any product under an
Appendix II approval class rating as specified in the approval schedule issued to the
particular organisation.
It therefore follows for example that a maintenance organisation approved under Part-145
with a capability to maintain aircraft, repair engines, brakes and autopilots would need to
carry out four complete audit sample checks each year except as specified otherwise in
subparagraphs 5, 7 or 9.
Issue-2 March, 2017 Civil Aviation Authority, Bangladesh 1-59
ANO (AW) Part-145 Approved Maintenance Organization
Chapter 1: Regulations & Acceptable Means of Compliance (Section A)
6. The sample check of a product means to witness any relevant testing and visually inspect the
product and associated documentation. The sample check should not involve repeat
disassembly or testing unless the sample check identifies findings requiring such action.
8. Except as specified otherwise in sub-paragraph 9, where the organisation has line stations
listed as per 145.A.75 (d) the quality system should describe how these are integrated into the
system and include a plan to audit each listed line station at a frequency consistent with the
extent of flight activity at the particular line station. Except as specified otherwise in sub-
paragraph 9 the maximum period between audits of a particular line station should not exceed
24 months.
10. A report should be raised each time an audit is carried out describing what was checked and
the resulting findings against applicable requirements, procedures and products.
11. The independence of the audit should be established by always ensuring that audits are
carried out by personnel not responsible for the function, procedure or products being
checked. It therefore follows that a large maintenance organisation approved under Part-145,
being an organisation with more than about 500 maintenance staff should have a dedicated
quality audit group whose sole function is to conduct audits, raise finding reports and follow
up to check that findings are being rectified. For the medium sized maintenance organisation
approved under Part-145, being an organisation with less than about 500 maintenance staff, it
is acceptable to use competent personnel from one section/department not responsible for the
production function, procedure or product to audit the section/department that is responsible
subject to the overall planning and implementation being under the control of the quality
manager. Organisations with a maximum of 10 maintenance staff actively engaged in
carrying out maintenance may contract the independent audit element of the quality system to
another organisation or a qualified and competent person approved by the Competent
Authority.
AMC 145.A.65(c)(2) Safety and quality policy, maintenance procedures and quality system
1. An essential element of the quality system is the quality feedback system.
2. The quality feedback system may not be contracted to outside persons. The principle function
of the quality feedback system is to ensure that all findings resulting from the independent
quality audits of the organisation are properly investigated and corrected in a timely manner
and to enable the accountable manager to be kept informed of any safety issues and the extent
of compliance with Part-145.
Issue-2 March, 2017 Civil Aviation Authority, Bangladesh 1-60
ANO (AW) Part-145 Approved Maintenance Organization
Chapter 1: Regulations & Acceptable Means of Compliance (Section A)
3. The independent quality audit reports referenced in AMC 145.A.65(c) (1) sub-paragraph 10
should be sent to the relevant department(s) for rectification action giving target rectification
dates. Rectification dates should be discussed with such department(s) before the quality
department or nominated quality auditor confirms such dates in the report. The relevant
department(s) are required by 145.A.65(c) (2) to rectify findings and inform the quality
department or nominated quality auditor of such rectification.
4. The accountable manager should hold regular meetings with staff to check progress on
rectification except that in the large organisations such meetings may be delegated on a day to
day basis to the quality manager subject to the accountable manager meeting at least twice
per year with the senior staff involved to review the overall performance and receiving at
least a half yearly summary report on findings of non-compliance.
5. All records pertaining to the independent quality audit and the quality feedback system
should be retained for at least 2 years after the date of clearance of the finding to which they
refer or for such periods as to support changes to the AMC 145.A.65(c)(1) sub-paragraph 9
audit time periods, whichever is the longer.
GM 145.A.65(c)(1) Safety and quality policy, maintenance procedures and quality system
1. The purpose of this GM is to give guidance on just one acceptable working audit plan to meet
part of the needs of 145.A.65 (c) 1. There is any number of other acceptable working audit
plans.
2. The proposed plan lists the subject matter that should be covered by the audit and attempts to
indicate applicability in the various types of workshops and aircraft facilities. The list should
therefore be tailored for the particular situation and more than one list may be necessary.
Each list should be shown against a timetable to indicate when the particular item is
scheduled for audit and when the audit was completed.
Note 2: In the line station case all line stations should be audited at the frequency agreed
with the Competent Authority within the limits of AMC 145.A.65(c) (1).

(b) The exposition shall be amended as necessary to remain an up-to-date description of the
organisation. The exposition and any subsequent amendment shall be approved by the
Competent Authority.
(c) Notwithstanding paragraph (b) minor amendments to the exposition may be approved
through an exposition procedure (hereinafter called indirect approval).
(d) The exposition shall refer to the Safety Management System Manual (SMSM).
The information specified in 145.A.70 (a) subparagraphs (6) and (12) to (16) inclusive, whilst a
part of the maintenance organisation exposition, may be kept as separate documents or on
separate electronic data files subject to the management part of said exposition containing a clear
cross-reference to such documents or electronic data files.
The exposition should contain the information, as applicable, specified in this AMC. The
information may be presented in any subject order as long as all applicable subjects are covered.
Where an organisation uses a different format, for example, to allow the exposition to serve for
more than one approval, then the exposition should contain a cross-reference Annex using this list
as an index with an explanation as to where the subject matter can be found in the exposition.
The exposition should contain information, as applicable, on how the maintenance organisation
complies with Critical Design Configuration Control Limitations‘ (CDCCL) instructions.
Small maintenance organisations may combine the various items to form a simple exposition
more relevant to their needs.
The operator may use electronic data processing (EDP) for publication of the maintenance
organisation exposition. The maintenance organisation exposition should be made available to the
Competent Authority in a form acceptable to the Competent Authority. Attention should be paid
to the compatibility of EDP publication systems with the necessary dissemination of the
maintenance organisation exposition, both internally and externally.

ANO (AW) Part-145 Approved Maintenance Organization
Chapter 1: Regulations & Acceptable Means of Compliance (Section A)
2. Compliance with its contents will assure compliance with the requirements of Part-145,
which is a prerequisite to obtaining and retaining a maintenance organisation approval
certificate.
3. 145.A.70 (a)(1) to (a)(11) constitutes the ‗management‘ part of the MOE and therefore could
be produced as one document and made available to the person(s) specified under 145.A.30
(b) who should be reasonably familiar with its contents. 145.A.70(a) (6) list of certifying staff
and B1 and B2 support staff may be produced as a separate document.
4. 145.A.70(a) (12) constitutes the working procedures of the organisation and therefore as
stated in the requirement may be produced as any number of separate procedures manuals. It
should be remembered that these documents should be cross-referenced from the
management MOE.
5. Personnel are expected to be familiar with those parts of the manuals that are relevant to the
maintenance work they carry out.
6. The organisation should specify in the MOE who should amend the manual particularly in the
case where there are several parts.
7. The quality manager should be responsible for monitoring the amendment of the MOE,
unless otherwise agreed by the Competent Authority, including associated procedures
manuals and submission of the proposed amendments to the Competent Authority. However
the Competent Authority may agree via a procedure stated in the amendment section of the
MOE that some defined class of amendments may be incorporated without prior approval by
the Competent Authority.
9. The accountable manager‘s exposition statement as specified under 145.A.70 (a)(1) should
embrace the intent of the following paragraph and in fact this statement may be used without
amendment. Any modification to the statement should not alter the intent.
This exposition and any associated referenced manuals define the organisation and
procedures upon which the Competent Authority ANO (AW) Part-145 approval is based as
required by 145.A.70. These procedures are approved by the undersigned and should be
complied with, as applicable, when work orders are being progressed under the terms of the
Part-145 approval.
Issue-2 March, 2017 Civil Aviation Authority, Bangladesh 1-68
ANO (AW) Part-145 Approved Maintenance Organization
Chapter 1: Regulations & Acceptable Means of Compliance (Section A)
It is accepted that these procedures do not override the necessity of complying with any new
or amended regulation published by the Competent Authority from time to time where these
new or amended regulations are in conflict with these procedures.
It is understood that the Competent Authority will approve this organisation whilst the
Competent Authority is satisfied that the procedures are being followed and work standards
maintained. It is further understood that the Competent Authority reserves the right to
suspend, limit or revoke the approval of the organisation if the Competent Authority has
evidence that procedures are not followed or standards not upheld.
Signed ........................................
Dated ..........................................
Whenever the accountable manager changes, it is important to ensure that the new
accountable manager signs the paragraph 9 statement at the earliest opportunity. Failure to
carry out this action could invalidate the Part-145 approval.
10. When an organisation is approved against any other Part containing a requirement for an
exposition, a supplement covering the differences will suffice to meet the requirements
except that the supplement should have an index showing where those parts missing from the
supplement are covered.
(a) Maintain any aircraft and/or component for which it is approved at the locations identified in
the approval certificate and in the exposition;
(b) Arrange for maintenance of any aircraft or component for which it is approved at another
organisation that is working under the quality system of the organisation. This refers to work
being carried out by an organisation not itself appropriately approved to carry out such
maintenance under this Part and is limited to the work scope permitted under 145.A.65 (b)
procedures. This work scope shall not include a base maintenance check of an aircraft or a
complete workshop maintenance check or overhaul of an engine or engine module;
(c) Maintain any aircraft or any component for which it is approved at any location subject to the
need for such maintenance arising either from the unserviceability of the aircraft or from the
(d) Maintain any aircraft and/or component for which it is approved at a location identified as a
line maintenance location capable of supporting minor maintenance and only if the
organisation exposition both permits such activity and lists such locations;
3.1 The fundamental reasons for allowing an organisation approved under Part-145 to sub-
contract certain maintenance tasks are:
(a) To permit the acceptance of specialised maintenance services, such as, but not
limited to, plating, heat treatment, plasma spray, fabrication of specified parts for
minor repairs / modifications, etc., without the need for direct approval by the
Competent Authority in such cases.
(b) To permit the acceptance of aircraft maintenance up to but not including a base
maintenance check as specified in 145.A.75(b) by organisations not appropriately
approved under Part-145 when it is unrealistic to expect direct approval by the
Competent Authority. The Competent Authority will determine when it is
unrealistic but in general it is considered unrealistic if only one or two
organisations intend to use the sub-contract organisation.
3.2 When maintenance is carried out under the sub-contract control system it means that for
the duration of such maintenance, the Part-145 approval has been temporarily extended
to include the sub-contractor. It therefore follows that those parts of the sub-contractor`s
facilities personnel and procedures involved with the maintenance organisation‘s
products undergoing maintenance should meet Part-145 requirements for the duration of
that maintenance and it remains the organisation‘s responsibility to ensure such
requirements are satisfied.
3.3 For the criteria specified in sub-paragraph 3.1 the organisation is not required to have
complete facilities for maintenance that it needs to sub-contract but it should have its
own expertise to determine that the sub-contractor meets the necessary standards.
However an organisation cannot be approved unless it has the in-house facilities,
procedures and expertise to carry out the majority of maintenance for which it wishes to
be approved in terms of the number of class ratings.
3.4 The organisation may find it necessary to include several specialist sub-contractors to
enable it to be approved to completely certify the release to service of a particular
product. Examples could be specialist welding, electro-plating, painting etc. To authorise
the use of such subcontractors, the Competent Authority will need to be satisfied that the
organisation has the necessary expertise and procedures to control such sub-contractors.
3.5 An organisation working outside the scope of its approval schedule is deemed to be not
approved. Such an organisation may in this circumstance operate only under the sub-
contract control of another organisation approved under Part-145.
4.2 The organisation approved under Part-145 needs to assess to what extent it will use the
sub-contractor`s facilities. As a general rule the organisation should require its own
paperwork, approved data and material/spare parts to be used, but it could permit the use
of tools, equipment and personnel from the sub-contractor as long as such tools,
equipment and personnel meet the requirement of Part-145. In the case of sub-contractors
who provide specialised services it may for practical reasons be necessary to use their
specialised services personnel, approved data and material subject to acceptance by the
organisation approved under Part-145.
4.3 Unless the sub-contracted maintenance work can be fully inspected on receipt by the
organisation approved under Part-145 it will be necessary for such organisation to
supervise the inspection and release from the sub-contractor. Such activities should be
fully described in the organisation procedure. The organisation will need to consider
whether to use its own staff or authorise the sub-contractor's staff.
4.4 The certificate of release to service may be issued either at the sub-contractor or at the
organisation facility by staff issued a certification authorisation in accordance with Part
145.A.30 as appropriate, by the organisation approved under Part-145. Such staff would
normally come from the organisation approved under Part-145 but may otherwise be a
person from the sub-contractor who meets the approved maintenance organisation
certifying staff standard which itself is approved by the Competent Authority via the
maintenance organisation exposition. The certificate of release to service and the CAAB
Form 1 will always be issued under the maintenance organisation approval reference.
4.5 The sub-contract control procedure will need to record audits of the sub-contractor, to
have a corrective action follow up plan and to know when sub-contractors are being
used. The procedure should include a clear revocation process for sub-contractors who
do not meet the Part-145 approved maintenance organisation‘s requirements.
4.6 The Part-145 quality audit staff will need to audit the sub-contract control section and
sample audit sub-contractors unless this task is already carried out by the quality audit
staff as stated in sub-paragraph 4.1.
4.7 The contract between the Part-145 approved maintenance organisation and the sub-
contractor should contain a provision for the Competent Authority to have right of access
to the sub-contractor.
6. the facilities, equipment, tools, material, procedures, work scope or certifying staff that could
affect the approval.
2. the Competent Authority being granted access to the organisation to determine continued
compliance with this Part; and
(b) Upon surrender or revocation, the approval shall be returned to the Competent Authority.
145.A.95 Findings
(a) A level 1 finding is any significant non-compliance with Part-145 requirements which lowers
the safety standard and hazards seriously the flight safety.
(b) A level 2 finding is any non-compliance with the Part-145 requirements which could lower
the safety standard and possibly hazard the flight safety.
(c) After receipt of notification of findings according to 145.B.50, the holder of the maintenance
organisation approval shall define a corrective action plan and demonstrate corrective action
to the satisfaction of the Competent Authority within a period agreed with this Competent
Authority.
Section B
Procedure for CAA
145.B.01 Scope
This section establishes the administrative procedures which the Civil Aviation Authority of
Bangladesh (CAAB) shall follow when exercising its tasks and responsibilities regarding
issuance, continuation, change, suspension or revocation of Part-145 maintenance organisation
approvals.
For the purpose of this Part, the Competent Authority shall be for organisations having their
principle place of business in Bangladesh shall be Chairman, CAAB.
Civil Aviation Authority of Bangladesh (CAAB) shall establish documented procedures and an
organisational structure.
2. Resources

section.
(a) be appropriately qualified and have all necessary knowledge, experience and training to
perform their allocated tasks.
(b) have received training/continuation training on Part-145 where relevant, including its
intended meaning and standard.
4. Procedures
Competent Authority shall establish procedures detailing how compliance with this Section B
is accomplished.
2. The Competent Authority should retain effective control of important surveillance functions
and not delegate them in such a way that Part-145 organisations, in effect, regulate
themselves in airworthiness matters.
3. The set-up of the organisational structure should ensure that the various tasks and obligations
of the Competent Authority are not relying on individuals. That means that a continuing and
undisturbed fulfilment of these tasks and obligations of the Competent Authority should also
be guaranteed in case of illness, accident or leave of individual employees.
1.1 practical experience and expertise in the application of aviation safety standards and safe
operating practices;
d. quality systems;
1.4 five years relevant work experience to be allowed to work as a inspector independently.
This may include experience gained during training to obtain the 1.5 qualification.

145.B.15
Reserved
2. The Competent Authority shall verify that the procedures specified in the maintenance
organisation exposition comply with Part-145 and verify that the accountable manager signs
the commitment statement.
3. The Competent Authority shall verify that the organisation is in compliance with the
requirements of Part-145.
4. A meeting with the accountable manager shall be convened at least once during the
investigation for approval to ensure that he/she fully understands the significance of the
approval and the reason for signing the exposition commitment of the organisation to
compliance with the procedures specified in the exposition.
6. The competent authority shall record all findings, closure actions (actions required to close a
finding) and recommendations.
7. For initial approval all findings must be corrected before the approval can be issued.
Issue-2 March, 2017 Civil Aviation Authority, Bangladesh 2-4
ANO (AW) Part-145 Approved Maintenance Organization
Chapter 2: Procedures for CAA & Acceptable Means of Compliance (Section B)
2. Formal indication of acceptance should be by use of the CAAB Form 4 or in the case of the
Accountable Manager via approval of the Maintenance Organisation Exposition containing
the Accountable Managers commitment statement.
3. The competent authority may reject an accountable manager where there is clear evidence
that he/she previously held a senior position in a Competent Authority approved Organisation
and abused that position by not complying with the particular Competent Authority
requirements.
2. It is recommended that the audit is carried out on a product line type basis in that, for
example, in the case of an organisation with Airbus A310 and A320 ratings, the audit be
concentrated on one type only for a full compliance check and dependent upon the result, the
second type may only require a sample check against those activities seen to be weak on
compliance for the first type.
3. The Competent Authority auditing inspector should always ensure that he/she is accompanied
throughout the audit by a senior technical member of the organisation. Normally this is the
quality manager. The reason for being accompanied is to ensure the organisation is fully
aware of any findings during the audit.
4. The auditing inspector should inform the senior technical member of the organisation at the
end of the audit visit on all findings made during the audit.
2. A quality review of the CAAB Form 6 audit report form should be carried out by a competent
independent person nominated by the Competent Authority. The review should take into
account the relevant paragraphs of Part-145, the categorisation of finding levels and the
closure action taken. Satisfactory review of the audit form should be indicated by a signature
on the audit form.
2. There may be occasions when the Competent Authority inspector may find situations in the
applicant's organisation on which he/she is unsure about compliance. In this case, the
organisation should be informed about possible non-compliance at the time and the fact that
the situation will be reviewed within the Competent Authority before a decision is made. If
the decision is a finding of being in compliance then a verbal confirmation to the organisation
will suffice.
3. Findings should be recorded on the audit report form with a provisional categorisation as a
level 1 or 2. Subsequent to the audit visit that identified the particular findings, the Competent
Authority should review the provisional finding levels, adjusting them if necessary and
change the categorisation from provisional to confirmed.
4. All findings should be confirmed in writing to the applicant organisation within 2 weeks of
the audit visit.
2. The Competent Authority shall indicate the conditions of the approval on the CAAB Form 3
approval certificate.
3. The reference number shall be included on the CAAB Form 3 approval certificate in a
manner specified by the Competent Authority.
For example, if the organisation is capable of maintaining within the limitation of Part-145
the Boeing 737-200 series aircraft the approval schedule should state A1 Boeing 737-200
series and not Boeing 737-2H6 which is a particular airline designator for one of many -200
series.
1. The Competent Authority shall keep and update a programme listing the approved
maintenance organisations under its supervision, the dates when audit visits are due and when
such visits were carried out.
2. Each organisation must be completely reviewed for compliance with Part-145 at periods not
exceeding 24 months.
3. A meeting with the accountable manager shall be convened at least once every 24 months to
ensure he/she remains informed of significant issues arising during audits.
the specific item audit should be the same as that required by Part-145 latest amendment,
and
there should be satisfactory evidence on record that such specific item audits were
carried out and that all corrective actions have been taken, and
the Competent Authority inspector(s) should be satisfied that there is no reason to believe
standards have deteriorated in respect of those specific item audits being granted a back
credit, and
the specific item audit being granted a back credit should be audited not later than 24
months after the last audit of the item.
145.B.35 Changes
1. The Competent Authority shall receive notification from the organisation of any proposed
change as listed in 145.A.85.
The Competent Authority shall comply with the applicable elements of the initial process
paragraphs for any change to the organisation.
2. The Competent Authority may prescribe the conditions under which organisation may
operate during such changes unless it determines that the approval should be suspended.
2. In the case an indirect approval procedure is used for the approval of the changes in
accordance with point 145.A.70(c), the Competent Authority shall ensure (i) that the changes
remain minor and (ii) that it has an adequate control over the approval of the changes to
ensure they remain in compliance with the requirements of Part-145.
2. The Competent Authority may define some class of amendments to the exposition which may
be incorporated without prior authority approval. In this case a procedure should be stated in
the amendment section of the MOE. The exposition chapter dealing with scope of
work/approval should not be subject to this procedure.
3. The organisation should submit each exposition amendment to the Competent Authority
whether it is an amendment for approval or a delegated approval amendment. Where the
amendment requires approval by the Competent Authority, the Competent Authority when
satisfied, should indicate its approval in writing. Where the amendment has been submitted
under the delegated approval procedure Competent Authority should acknowledge receipt in
writing.
(a) suspend an approval on reasonable grounds in the case of potential safety threat; or
145.B.50 Findings
(a) When during audits or by other means evidence is found showing non-compliance with the
requirements of Part-145, the Competent Authority shall take the following actions:
1. For level 1 findings, immediate action shall be taken by the Competent Authority to
revoke, limit or suspend in whole or in part, depending upon the extent of the level 1
finding, the maintenance organisation approval, until successful corrective action has
been taken by the organisation.
2. For level 2 findings, the corrective action period granted by the Competent Authority
must be appropriate to the nature of the finding but in any case initially must not be more
than three months. In certain circumstances and subject to the nature of the finding the
Competent Authority may extend the three month period subject to a satisfactory
corrective action plan agreed by the Competent Authority.
(b) Action shall be taken by the Competent Authority to suspend in whole or part the approval in
case of failure to comply within the timescale granted by the Competent Authority.
Failure to gain access to the organisation during normal operating hours of the
organisation in accordance with 145.A.90(2) after two written requests.
Note: A complete product line is defined as all the aircraft, engine or component of a
particular type.
For a level 1 finding it may be necessary for the Competent Authority to ensure that further
maintenance and re-certification of all affected products is accomplished, dependent upon the
nature of the finding.
In practical terms where a Competent Authority inspector finds a non-compliance with Part-145
against one product, it is deemed to be a level 2 finding.
145.B.55 Record-keeping
1. The Competent Authority shall establish a system of record-keeping with minimum retention
criteria that allows adequate traceability of the process to issue, continue, change, suspend or
revoke each individual organisation approval.
2. The records shall include as a minimum:
(a) the application for an organisation approval, including the continuation thereof.
(b) the Competent Authority continued oversight program including all audit records.
(c) the organisation approval certificate including any change thereto.
(d) a copy of the audit program listing the dates when audits are due and when audits were
carried out.
(e) copies of all formal correspondence including Form 4 or equivalent.
(f) details of any exemption and enforcement action(s).
(g) any other competent authority audit report forms.
(h) maintenance organisation expositions.
3. The minimum retention period for the above records shall be four years.
4. The Competent Authority may elect to use either a paper or computer system or any
combination of both subject to appropriate controls.
2. All records containing sensitive data regarding applicants or organisations should be stored in
a secure manner with controlled access to ensure confidentiality of this kind of data.
3. All computer hardware used to ensure data backup should be stored in a different location
from that containing the working data in an environment that ensures they remain in good
condition. When hardware or software changes take place special care should be taken to
ensure that all necessary data continues to be accessible at least through the full period
specified in 145.B.55.
145.B.60 Exemptions
All exemptions granted by the Competent Authority shall be recorded and retained by the
Competent Authority.

limited to the entry made in block 11.
Appendix II
- Class and Ratings System used for the Approval of Maintenance
Organizations referred to Part-145
1. Except as stated otherwise for the smallest organisations in paragraph 12, the table referred to
in point 13 provides the standard system for the approval of maintenance organisation under
Subpart F Part-M and Part-145. An organisation must be granted an approval ranging from a
single class and rating with limitations to all classes and ratings with limitations.
2. In addition to the table referred to in point 13, the approved maintenance organisation is
required to indicate its scope of work in its maintenance organisation manual/exposition. See
also paragraph 11.
3. Within the approval class(es) and rating(s) granted by the Competent Authority the scope of
work specified in the maintenance organisation exposition defines the exact limits of approval.
It is therefore essential that the approval class(es) and rating(s) and the organisations scope of
work are matching.
4. A category A class rating means that the approved maintenance organisation may carry out
maintenance on the aircraft and any component (including engines and/or Auxiliary Power
Units (APUs), in accordance with aircraft maintenance data or, if agreed by the Competent
Authority, in accordance with component maintenance data, only whilst such components are
fitted to the aircraft. Nevertheless, such A-rated approved maintenance organisation may
temporarily remove a component for maintenance, in order to improve access to that
component, except when such removal generates the need for additional maintenance not
eligible for the provisions of this paragraph. This will be subject to a control procedure in the
maintenance organisation exposition to be approved by the Competent Authority. The
limitation section will specify the scope of such maintenance thereby indicating the extent of
approval.
5. A category B class rating means that the approved maintenance organisation may carry out
maintenance on the uninstalled engine and/or APU and engine and/or APU components, in
accordance with engine and/or APU maintenance data or, if agreed by the Competent
Authority, in accordance with component maintenance data, only whilst such components are
fitted to the engine and/or APU. Nevertheless, such B-rated approved maintenance
organisation may temporarily remove a component for maintenance, in order to improve
access to that component, except when such removal generates the need for additional
maintenance not eligible for the provisions of this paragraph. The limitation section will
specify the scope of such maintenance thereby indicating the extent of approval. A
maintenance organisation approved with a category B class rating may also carry out
maintenance on an installed engine during „base‟ and „line‟ maintenance subject to a control
procedure in the maintenance organisation exposition to be approved by the competent
authority. The maintenance organisation exposition scope of work shall reflect such activity
where permitted by the Competent Authority.
6. A category A Class rating means that the approved maintenance organisation may carry out
maintenance on uninstalled components (excluding engines and APUs) intended for fitment to
the aircraft or engine/APU. The limitation section will specify the scope of such maintenance
thereby indicating the extent of approval. A maintenance organisation approved with a
category C class rating may also carry out maintenance on an installed component during base
and line maintenance or at an engine/APU maintenance facility subject to a control procedure
in the maintenance organisation exposition to be approved by the competent authority. The
maintenance organisation exposition scope of work shall reflect such activity where permitted
by the Competent Authority.
7. A category D class rating is a self-contained class rating not necessarily related to a specific
aircraft, engine or other component. The D1 - Non Destructive Testing (NDT) rating is only
necessary for an approved maintenance organisation that carries out NDT as a particular task
for another organisation. A maintenance organisation approved with a class rating in A or B or
C category may carry out NDT on products it is maintaining subject to the maintenance
organisation exposition containing NDT procedures, without the need for a D1 class rating.
10.When reference is made to series, type and group in the limitation section of class A and B,
series means a specific type series such as Airbus 300 or 310 or 319 or Boeing 737-300 series
or RB211-524 series or Cessna 150 or Cessna 172 or Beech 55 series or continental O-200
series etc; type means a specific type or model such as Airbus 310-240 type or RB 211-524 B4
type or Cessna 172RG type; any number of series or types may be quoted; group means for
example Cessna single piston engine aircraft or Lycoming non-supercharged piston engines
etc.
11. When a lengthy capability list is used which could be subject to frequent amendment, then
such amendment shall be in accordance with a procedure acceptable to Competent Authority
and included in the maintenance organisation exposition. The procedure shall address the
issues of who is responsible for capability list amendment control and the actions that need to
be taken for amendment. Such actions include ensuring compliance with Part-145 for products
or services added to the list.
12. A maintenance organisation which employs only one person to both plan and carry out all
maintenance can only hold a limited scope of approval rating. The maximum permissible limits
are:
It should be noted that such an organisation may be further limited by the Competent Authority in
the scope of approval dependent upon the capability of the particular organisation.
