What maintenance record is required following a major repair of an aircraft engine?

Following a major repair of an aircraft engine, it is essential to maintain specific documentation that ensures compliance with regulatory requirements. The correct option emphasizes the necessity of both the FAA Form 337 and the GACA Form 8320-1.

The FAA Form 337 is crucial because it documents any major repairs or alterations made to the aircraft, ensuring that the work performed is officially recorded and recognized by the regulatory body. This form provides essential information about the specifics of the repair, including a description of the work done, the date of completion, and the signatures of the involved parties.

Similarly, the GACA Form 8320-1 serves a parallel purpose but is tailored to meet the standards and regulations set forth by the General Authority of Civil Aviation in the relevant jurisdiction. This ensures that the repair adheres to local aviation safety standards and regulations.

Together, these two forms create a comprehensive record of the major repair made, providing both regulatory compliance and essential information for future maintenance and inspection activities. This rigorous documentation process is vital for ensuring the continued safety and airworthiness of the aircraft, making it important to follow these practices diligently.
