In 14 CFR Part 43 Appendix A, which document, if the alteration is listed in it, would cause the operation to be considered a minor alteration?

• A. Aircraft Specifications issued by the FAA
• B. Supplemental Type Certificates
• C. Manufacturer's Maintenance Manual
• D. Airworthiness Directives

Answer: (A)

In Appendix A to 14 CFR Part 43, minor alterations are those that are already listed in the aircraft’s FAA-approved data, specifically the Aircraft Specifications (the type certificate data sheet). If an alteration is included there, it’s considered part of the approved design and does not require the more extensive major-alteration process. Modifications listed in Supplemental Type Certificates are separate design changes and are not automatically treated as minor. Airworthiness Directives address safety issues and mandate actions, but they don’t establish a minor alteration classification. The manufacturer’s maintenance manual provides guidance for maintenance procedures, not a basis for classifying alterations. Therefore, the alteration listed in the Aircraft Specifications issued by the FAA is the one that would cause the operation to be considered a minor alteration.
