EUROPEAN UNION AVIATION SAFETY AGENCY (EASA) HAS ISSUED A NEW COMMISSION IMPLEMENTING REGULATION (EU) 2025/111

European Union Aviation Safety Agency (EASA) has issued a new Commission Implementing Regulation (EU) 2025/111 of January 23, 2025, revising Regulation (EU) No 1321/2014 regarding the continued airworthiness of electric and hybrid-propelled aircraft, as well as other non-conventional aircraft. Commission Regulation (EU) No 1321/2014 establishes the requirements for aircraft’s continued airworthiness, including the qualifications and licenses of personnel responsible for returning products to service after maintenance, but previous versions of the regulation did not fully cover all eVTOL aircraft types.

According to the new rule:

“By considering all tilt-rotors as complex motor-powered aircraft, Regulation (EU) No 1321/2014 was not commensurate for the simplest ones as stringent requirements applicable to any complex motor-powered aircraft was also applicable to the simplest tilt-rotors, for which less stringent requirements should apply by comparison with simple aircraft of other categories, namely aeroplanes and helicopters. Therefore the definition of complex motor-powered aircraft should therefore be amended.”

The new rule broadly brings eVTOLs within the umbrella of EU rules covering maintenance and support of all EU-registered aircraft. For example, eVTOL operators will need to ensure their maintenance programs have been approved by the competent authority in accordance with point M.A.302 of Annex I (Part-M), due maintenance has been performed and certified in accordance with point 145.A.48 and 145.A.50 of Annex II (Part-145), and an airworthiness review has

In this context, a new category has been added to aircraft maintenance licenses: B1.E - (MTOM < 5,700 kg).
