Master Minimum Equipment Lists (MMELS)

The transition of MMEL/OEB Reports to Operational Suitability Data (OSD) has been implemented.
Accordingly, some MMEL/OEB Reports have been withdrawn from the EASA webpages and the associated OSD documents are held by the manufacturer (TC/STC holder).
TCHs that have provided OSD contact information to EASA are listed in the OSD Contact List page.
Operational Evaluation Guidance Material (OE GM) is published, if developed, where no OSD FC documents exist to assist Competent Authorities, operators, training organisations, instructors and any other personnel involved in flight crew training and air operations. OE GM documents do not establish any regulatory requirements and do not constitute Operational Suitability Data (neither mandatory nor non-mandatory elements).
