Which document is used to describe a major repair when approving for return to service?

• A. FAA Form 337.
• B. FAA Form 7810-3.
• C. Maintenance Manual.
• D. Maintenance log.

Answer: (A)

When approving an aircraft for return to service after a major repair, you use FAA Form 337, Report of Major Repair or Major Alteration. This form provides a detailed description of the repair or alteration performed, identifies what was affected, and captures the signatures of the person who performed the work and the person approving it for return to service. It serves as the formal FAA-approved record that the work was completed to required standards and that the aircraft is airworthy again; the document becomes part of the aircraft’s maintenance records for the life of the aircraft. A maintenance manual is the source of procedures and standards for performing repairs, but it does not document FAA approval or authorize return to service. The maintenance log records maintenance events, but it does not replace the formal approval and description required for major repairs. FAA Form 7810-3 is an airworthiness approval tag used for individual parts, not the overall description and FAA approval for a major repair on an entire aircraft.
