MOSAIC is done. After more than a decade of work by EAA, the FAA, and numerous others, MOSAIC (Modernization of Special Airworthiness Certification) is now a final rule. The rule was announced by U.S. Secretary of Transportation Sean Duffy on Tuesday afternoon at EAA AirVenture Oshkosh 2025. A generation after the creation of the original sport pilot and light-sport aircraft (LSA) rules, today we celebrate Sport Pilot 2.0 and LSA 2.0. Ninety days from now, about three-quarters of the general aviation fleet will be accessible to sport pilots and those exercising sport pilot privileges. One year from now, new and modern aircraft will begin entering the fleet with minimal certification costs. //
With MOSAIC, the weight limitation is removed. GONE! In its place is a new set of limitations; the primary limitation will now be a “clean” stall speed (VS1) of 59 knots calibrated airspeed. Aircraft with up to four seats are now allowed, although sport pilots will still be limited to one passenger. Sport pilots are also now allowed to fly aircraft with controllable-pitch propellers and retractable landing gear, with the appropriate training and endorsements.
Equally exciting to the future of aviation is the aircraft certification reform included in the rule. New aircraft are on the way! The original LSA rule proved that safe, modern aircraft could be certified with a minimum of FAA oversight by using industry consensus standards and simple forms of validation. Now, LSA 2.0 is set to deliver far more capability.
