@Larscho, @Airborne again, vi tolkar samma. Men det känns definitivt som kompendiet tolkar det strängare än så. Problemet var vad jag förstår är att det verkar krävas en MMEL för att göra en MEL. Dock finns en GM som kanske vagt, skulle tillåta referens till CS om en MMEL inte finns, fast det är så otydligt så jag vet inte. GM1 NCO.GEN.155 Minimum equipment list GENERAL (a) The Minimum Equipment List (MEL) is a document that lists the equipment that may be temporarily inoperative, subject to certain conditions, at the commencement of flight. This document is prepared by the operator for their own particular aircraft, taking account of their aircraft configuration and all those individual variables that cannot be addressed at MMEL level, such as operating environment, route structure, geographic location, aerodromes where spare parts and maintenance capabilities are available, etc. (b) The MMEL, as defined in the mandatory part of the operational suitability data established in accordance with Regulation (EU) No 748/2012, is developed in compliance with CS-MMEL or CSGEN- MMEL. These Certification Specifications contain, among other, guidance intended to standardise the level of relief granted in MMELs, in particular for items that are subject to operational requirements. If an MMEL established as part of the operational suitability data is not available and items subject to operational requirements are listed in the available MMEL without specific relief or dispatch conditions but only with a reference to the operational requirements, the operator may refer to CS-MMEL or CS-GEN-MMEL guidance material, as applicable, to develop the relevant MEL content for such items.
