EASA ED Decision 2026/001/R, New air mobility | Continuing airworthiness rules for electric- and hybrid-propulsion aircraft and other non-conventional aircraft

The objective of this Decision is to issue amendments to CS-MCSD to support the implementation of Commission Implementing Regulation (EU) 2025/111 as regards the continuing airworthiness for electric- and hybrid-propulsion aircraft and other non-conventional aircraft.

The amendments adapt CS-MCSD so that they can be considered by type-certificate applicants when identifying in the operational suitability data (OSD) of certain aircraft, namely new air mobility aircraft, the training requirements for maintenance certifying staff, since such training is not defined in Annex III (Part-66) to Commission Regulation (EU) No 1321/2014 for such aircraft.

The update of CS-MCSD, together with the requirements of Appendix III ‘Aircraft type training and examination standard’ to Annex III (Part-66), shall form the basis for the development and approval of Part-66 type-rating training courses for new air mobility aircraft.

Overall, this Decision is intended to facilitate new air mobility aircraft applicants’ compliance with the OSD requirements by using the specifications contained in CS-MCSD Issue 2
