Getting to Grips with MMEL and MEL

Cathay.pacific.a340-600.b-hqb.arpThe MMEL is an Airbus document, developed by the Flight Operations Support and Services Department. Operators use the Airbus MMEL as a reference for creating their own MEL, which is provided to their flight crews, line maintenance personnel, and/or flight operations personnel. It is important to note that an Operator’s MEL cannot be less restrictive than the Airbus MMEL.

The MMEL and the MEL are both designed to ensure that an acceptable level of safety is respected, when an aircraft is dispatched with inoperative equipment. The MEL enables Operators to rapidly dispatch an aircraft, and avoid unnecessary delays or flight cancellations, without sacrificing safety. Both the MMEL and the MEL are legal documents that are either approved or accepted by Airworthiness Authorities. The MMEL and the MEL consist of component and system lists that are attributed a ”GO”, ”GO IF”, or ”NO GO” status, depending on their impact on the safety of a flight.
