Which statement best describes a major airframe repair or major alteration by a certificated mechanic with appropriate rating?

• A. It may be performed and the work may be approved for return to service
• B. It may be performed but cannot be approved for return to service
• C. It may be performed only with FAA approval for return to service
• D. It may not be performed by a certificated mechanic

Answer: (B)

Major airframe repairs or major alterations are significant actions that must be done according to approved data and then approved for return to service by someone with proper authority. A certificated mechanic with the appropriate rating can perform the repair or alteration, but the confirmation that the aircraft is airworthy again after the work cannot be given by that mechanic alone unless they also hold the authority to certify airworthiness (such as an IA or an FAA inspector). In short, the job itself can be done by the right-rated mechanic, but the return-to-service approval comes from someone with the proper certification to certify airworthiness.
