Which document assists with managing inoperative items while maintaining safety?

The Maintenance Minimum Equipment List, or MMEL, is an essential document that provides guidelines for managing inoperative items on an aircraft while ensuring safety remains a priority. It outlines which systems or components may be inoperative for a flight to occur legally and safely, detailing specific conditions under which the aircraft can operate despite certain items being inoperative. This list is very important because it helps operators and maintenance personnel make informed decisions about aircraft dispatch and safety compliance under defined criteria.

Incorporating MMEL into operational procedures enables flight crews to assess the impact of inoperative equipment on the aircraft's operational capabilities effectively while adhering to regulatory safety standards. The MMEL serves as a foundational reference point during flight planning and maintenance checks to ensure that any inoperative item does not compromise the overall safety of the operation.

Other documents like CODDE 1, Fault Guide, and CODDE 3 may provide support in their respective areas—such as operational data or troubleshooting—but they do not specifically focus on the safe management of inoperative items in the same comprehensive manner as the MMEL.
