Where must approval for a Minimum Equipment List (MEL) be obtained from?

The Minimum Equipment List (MEL) is a critical document that outlines the equipment that may be inoperative for an aircraft to be deemed airworthy. To ensure compliance with safety regulations and operational efficacy, the approval for an MEL must be obtained from the Federal Aviation Administration (FAA) district office. This office plays a significant role in regulating aviation standards and ensuring that aircraft operations meet safety requirements.

The process involves submitting a detailed list of equipment and the conditions under which the aircraft can still be operated safely without that equipment. The FAA evaluates this list to ensure that the operational risks are adequately mitigated, thus maintaining overall safety in aviation operations.

While other options may relate to the operational or maintenance aspects of an aircraft, they do not have the regulatory authority to approve an MEL. The Flight Standards District Office also does not hold the same direct approval responsibility as the FAA district office. Therefore, obtaining approval from the FAA district office is essential for the legitimate use of an MEL in compliance with federal regulations.
