What document is used to record the performance of major repairs according to FAA regulations?

The correct answer is the FAA Form 337, which is specifically designated for documenting Major Repairs and Major Alterations to aircraft. This form is crucial because it provides a formal record of the repair or alteration work that has been performed, ensuring compliance with FAA regulations.

When a major repair or alteration is completed, Part 43 of the Federal Aviation Regulations mandates that the findings and details of the work must be documented using FAA Form 337. This form includes essential information such as technical data regarding the repair or alteration, the approved data reference used, and the certifications of the individuals who performed and supervised the work.

Proper use of FAA Form 337 is vital for maintaining accurate maintenance records and is especially important during inspections and for tracking the airworthiness history of the aircraft.

While the other document types are relevant to aviation maintenance, they do not fulfill the specific requirement for recording major repairs and alterations. Maintenance manuals provide guidance on performing repairs but do not serve as a recording tool. Repair station maintenance releases pertain to the overall release of an aircraft after maintenance, rather than documenting individual major repairs. Service bulletins are informative rather than regulatory documents, offering manufacturer recommendations for maintenance but not serving as official record-keeping for major repairs or alterations.
