In the opinion of the European Aviation Safety Agency there should be a light Part-M (Part-ML) with requirements that would be “proportional to the much lower complexity and associated risks of the lighter end of the general aviation community, and as clear and simple as possible in order to facilitate implementation.”



Specifically, Part-ML proposes alleviations for aircraft maintenance programs and airworthiness reviews, and covers aircraft not listed in the air operator certificate of an air carrier and not classified as a complex motor-powered aircraft. As such, Part-ML would apply to airplanes of 2,720 kg (6,019 pounds) mtow or less and rotorcraft with mtows of 1,200 kg (2,645 pounds) or less and certified for a maximum of four occupants.



This opinion would not apply to jets or multi-engine turboprops because these airplanes are classified as complex motor-powered. However, single-engine turboprops with mtows of 6,019 pounds or less would fall into the proposed Part-ML. These airplanes would include the Piper Meridian/M500 and in-development M600, as well as the Extra EA-500.
