What records are required following a major repair of an aircraft engine?

Following a major repair of an aircraft engine, it is essential to maintain comprehensive documentation to ensure compliance with regulatory requirements and to provide accurate history for the engine's maintenance. The correct answer includes the requirement for entries in the engine maintenance record and the completion of FAA Form 337.

The engine maintenance record serves as an official log that details the history of all maintenance actions performed on the engine, including repairs, overhauls, and modifications. This record is crucial for tracking the maintenance status and ensuring that the engine adheres to its service requirements.

FAA Form 337, which documents major repairs and alterations, is also vital as it provides the FAA with information about the repair performed, including details regarding the nature of the repair, parts used, and the signature of the approving mechanic or repair station. This form is a regulatory requirement and must be submitted to the FAA as a record of the work done. Keeping thorough records on both the maintenance record and the FAA Form 337 supports ongoing safety and regulatory compliance.

Other documents, such as repair logs, manufacturer warranty documents, or service bulletins, may be valuable for maintenance practices but do not fulfill the specific regulatory requirements mandated for major repairs. The focus on both the engine maintenance record and FAA Form 337 leaves
