Where are the requirements for recording Major Repairs or Alterations found?

The requirements for recording Major Repairs or Alterations are outlined in FAR Part 43, specifically in Appendix B. This section of the Federal Aviation Regulations provides comprehensive guidelines for the proper documentation required after performing major repairs or alterations on aircraft. It emphasizes the importance of maintaining clear records that include details about the nature of the work performed, ensuring safety and compliance with regulations.

This documentation is crucial not only for maintaining the aircraft's airworthiness but also for compliance with regulatory requirements during inspections and audits. FAR Part 43 establishes the standards for the maintenance, preventive maintenance, and alteration of aircraft, making it the appropriate regulatory framework for this type of record-keeping.

The other options do not pertain to the correct regulatory framework for documenting major repairs or alterations, as they focus on different aspects of airworthiness or certification that do not specifically address the recording requirements.
