Which statement about minor alterations and return to service is true?

• A. They may be approved for return to service by the aircraft owner
• B. They require FAA authorization even if minor
• C. They may be approved for return to service by certificated mechanics who performed them and hold appropriate ratings
• D. They cannot be approved for return to service

Answer: (C)

After maintenance or a minor alteration, the person who is qualified and actually performed the work is the one who can approve the aircraft for return to service. If a certificated mechanic with the appropriate rating did the work, they may sign off and document that the aircraft is airworthy again. This ensures the decision is made by someone with the proper qualifications and firsthand knowledge of the work done. The other statements don’t fit because the owner cannot automatically sign off unless they are a certificated mechanic with the right rating, minor work doesn’t require a separate FAA authorization beyond the mechanic’s return-to-service sign-off, and the idea that nothing can be approved is incorrect.
