Maintenance Program History
The aircraft manufacturer became the source of maintenance program development. Time
limitations were established for maintenance and the entire aircraft was periodically
disassembled, overhauled, and reassembled in an effort to maintain the highest level of safety.
This was the origin of the first primary maintenance process referred to as Hard-Time (HT).
In 1960 representatives from both the FAA and the airlines formed a task force to investigate
the capabilities of preventive maintenance. The findings of the task force led to the
development of a second primary maintenance process
defined as On-Condition (OC). On-Condition requires that an appliance or part be
periodically inspected or checked against some appropriate physical standard to determine
whether it can continue in service. The purpose of the standard is to remove the unit from
service before failure during normal operation occurs.
