Key Takeaways:

ASTM's Weight-Shift Control Sub Committee successfully passed the Design and Performance Standard for "trikes."
This approval allows trikes to be manufactured and sold as Special Light-Sport Aircraft (S-LSAs) once the FAA issues a Notice of Availability.
Trikes will join fixed-wing airplanes and powered parachutes in the S-LSA category, with Australia also planning to adopt the U.S. Sport Pilot/Light-Sport Aircraft regulation.

After a detailed review, ASTM’s Weight-Shift Control Sub Committee got their Design and Performance Standard through final ballot. This was reported at the mid-May ’05 ASTM Committee meeting for Light-Sport Aircraft. Once FAA issues their Notice of Availability trikes can be manufactured and sold as S-LSAs, joining fixed wing airplanes and powered parachutes. AirBorne trikes (photo) have Australian certification plus now that country plans to adopt the entire U.S. Sport Pilot/Light-Sport Aircraft regulation. To keep up with the growing list of aircraft that have received their certificates, one good source is EAA’s Sport Pilot website.
