Under 14 CFR Part 43 Appendix A, an operation is considered a major alteration unless listed in which document?

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

Answer: (A)

In Part 43 Appendix A, whether an operation is considered a major alteration hinges on an official listing. If the proposed change is included in the FAA-issued Aircraft Specifications for that aircraft, it is not treated as a major alteration. If it isn’t on that list, the change is considered major because it could affect weight, balance, structural integrity, or aerodynamic characteristics and thus requires the higher level of FAA approval. Other documents like Supplemental Type Certificates, the manufacturer's maintenance manual, or service bulletins don’t provide that official listing used to classify major versus minor alterations.
