The EAA (Experimental Aircraft Association) recently filed a petition with the US Federal Aviation Administration (FAA) to request regulatory exemptions that would allow the use of electric motors in ultralight and light-sport aircraft.
EAA’s petition to the FAA specifically proposes specifications for battery-pack weight limits on ultralight aircraft and the development and adoption of electric-motor ASTM standards for light-sport aircraft.
The request for those specifications, combined with suggested language changes to remove exclusive references to reciprocating engines, would make electric motors legal for these aircraft.—Earl Lawrence, EAA’s vice president of industry and regulatory affairs
The request for exemption highlights developments already made in the automotive, radio-controlled aircraft, and light-aircraft industries.
