Advisory Circulars, in the context of major repairs, are considered approved data for major repairs?

• A. Yes
• B. No
• C. Only when used with STC
• D. Only for minor repairs

Answer: (B)

For major repairs, you must base the work on data that the FAA has approved for that specific repair. Advisory Circulars provide guidance and describe acceptable means of compliance, but they are not themselves FAA-approved data that authorize a repair. You cannot rely on an AC as the sole basis for a major repair; you need data such as manufacturer repair data that’s approved under an STC, PMA, field approval, or other FAA-approved data packages. An AC could help explain how to comply or illustrate a method, but it does not by itself approve the repair. The only time an AC would be involved in the approval is if its guidance has been incorporated into an FAA-approved data package. So, advisory circulars are not considered approved data for major repairs.
