Which data could be used as approved data for a major repair?

• A. Data developed by an A&P and approved by the holder of an inspection authorization.
• B. Data developed for and incorporated in a supplemental type certificate.
• C. Data developed by a repair station and approved by the operator.
• D. Data from the manufacturer’s external memo.

Answer: (B)

Major repairs must be performed in accordance with approved data. Approved data means information that has been reviewed and authorized by the FAA or by an FAA-approved design authority, such as an STC, PMA, or the design data tied to a type certificate. Data developed for and incorporated in a supplemental type certificate is FAA-approved design data that specifies exactly what needs to be done for the repair or alteration, making it valid for use in a major repair. The other sources don’t provide FAA-approved design data. Approval by an IA alone doesn’t create approved data for the repair. Data approved by the operator isn’t FAA-approved data and isn’t acceptable for major repairs. A manufacturer’s external memo by itself isn’t automatically FAA-approved design data unless it has been incorporated into an FAA-approved program (like an STC, PMA, or AD). So the STC-based data is the valid source for an approved major repair.
