FAA Military Competency Practice Exam

What information must a maintenance record for an aircraft engine rebuilt by the manufacturer include?

1. Standard operating procedures

2. Previous changes required by Airworthiness Directives

3. Environmental controls

4. Roles and responsibilities of personnel

The correct answer is: Previous changes required by Airworthiness Directives

The maintenance record for an aircraft engine rebuilt by the manufacturer must include previous changes required by Airworthiness Directives. This information is crucial because Airworthiness Directives are issued by aviation authorities to address safety issues affecting an aircraft or its components. They mandate specific actions to be taken to ensure continued airworthiness. By documenting previous changes required by these directives, the maintenance record ensures that all necessary compliance actions have been addressed and the engine meets safety and regulatory standards. This record serves as a vital reference for future maintenance and inspections, helping to ensure the aircraft's safe operation. The other options, while relevant in other contexts, do not specifically address the mandatory compliance documentation required for an engine rebuild. Standard operating procedures, environmental controls, and roles and responsibilities of personnel may be part of operational manuals or internal documentation but are not critical elements required in maintenance records for tracking compliance with Airworthiness Directives.
