Who is authorized to approve an aircraft return to service after a major repair?

• A. An aircraft mechanic holding an Inspection Authorization.
• B. The pilot in command.
• C. An FAA inspector.
• D. A maintenance supervisor.

Answer: (A)

The ability to approve an aircraft for return to service after a major repair rests with the person authorized to certify airworthiness after significant maintenance. An aircraft mechanic who holds an Inspection Authorization (IA) is that authority. The IA has demonstrated the required knowledge and experience to inspect the work, verify that it was performed according to approved data and regulations, and sign off on the maintenance records and the release to service. The pilot in command can operate the aircraft but does not certify airworthiness. An FAA inspector may evaluate airworthiness, but the routine release after major work is typically signed by the IA who performed or supervised the inspection, not by the pilot or a non-IA supervisor. Therefore, the IA is the best answer for who can approve the return to service after a major repair.
