Accepted Consensus Standards for Light-Sport Category Aircraft: Airplane, Glider, Powered Lift, and Gyroplane
FAA accepts updated ASTM consensus standards for Light-Sport Category Aircraft, affecting compliance methods for special airworthiness certificates.
Aforeworn detected this change in the Aviation Maintenance & Airworthiness (FAA) space on July 16, 2026 and published this briefing so affected operators are forewarned rather than caught off guard. It is rated Medium urgency. Part 145 repair stations, Part 135/121 operators, flight schools, corporate flight departments, and LSA manufacturers/owners should confirm how it applies to their specific situation before acting. There is a time constraint attached: Ongoing; compliance expected upon next maintenance event or certification action.. Acting after that point can mean penalties, a lapsed licence, or lost eligibility — exactly the kind of surprise Aforeworn exists to prevent. Aforeworn monitors Aviation Maintenance & Airworthiness (FAA) continuously and turns every detected change into a plain-English briefing like this one, so you always know first. Forewarned is forearmed.
