Records of AD compliance must contain which of the following?

Records of AD compliance must include the method of compliance because it provides detailed information on how the directive was addressed. This is critical for demonstrating that the required actions were taken to ensure safety and adhere to regulatory standards. The method of compliance outlines the specific procedures followed or alterations made to the aircraft, thereby ensuring a clear record for future reference and accountability.

Having a detailed method of compliance allows for consistency in maintenance practices and enables other technicians or inspectors to understand what actions were taken, fostering a culture of safety and reliability in aviation operations. The inclusion of this information is essential for compliance audits and inspections, as it directly addresses how the compliance was achieved.
