ED Decision 2025/021/R
(a) The generic MMEL includes all the items that are permitted to be inoperative.
The MMEL item list is generated by the applicant directly from the generic MMEL by selecting the items from the list in Appendix IV in accordance with their applicability to the aircraft type.
For an aircraft type with different configurations, the applicant can select all the items that are applicable to the various configurations and add under each affected item ‘(if installed)’.
For the selected items, the applicant verifies that they do not deviate from the Aircraft Flight Manual (AFM) Limitations and Airworthiness Directives.
The applicant also verifies that relief is not given for items that are involved in emergency procedures unless the applicant justifies that the emergency procedure can be fulfilled without the failed item (e.g. VHF Communication Systems).
Consistency of terminology and of means of identification should be maintained, as far as possible, with the existing aircraft documentation.
(b) For aeroplanes that meet the definition of ELA 1 or ELA 2, when the applicant elects to comply with this CS-GEN-MMEL, the MMEL item list may be generated, alternatively to the methodology in paragraph (a), using the list of required equipment included in the TCDS and/or AFM as a baseline. This list, in combination with the equipment required for the flight, establishes the list of equipment that must be operative for all flights. The list of any additional installed equipment that may be inoperative will constitute the MMEL to be approved.
CS GEN.MMEL.145 requires the applicant to generate the MMEL item list from the generic MMEL, verifying no deviation from AFM Limitations and Airworthiness Directives, with an alternative baseline for ELA 1 or ELA 2 aerop
