FAA’s MOSAIC Rules Set to Revolutionize General Aviation from July 24
A landmark moment for general aviation is just around the corner: on July 24, 2026, the final provisions of the FAA’s MOSAIC (Modernization of Special Airworthiness Certification) rules take full effect. This completes the most sweeping overhaul of Light Sport Aircraft (LSA) regulations since 2004, promising transformative changes for pilots, aircraft owners, and mechanics alike.
The new rules remove the long-standing 1,320-pound maximum takeoff weight limit for light-sport category aircraft. In its place, a performance-based stall speed criterion of 59 knots calibrated airspeed has been introduced. This significant change allows manufacturers to design larger, faster, and more capable aircraft. These can include those with retractable landing gear, constant-speed propellers, up to four seats, and even electric propulsion systems, all while still qualifying for the light-sport category.
Sport pilots stand to gain access to roughly three-quarters of the general aviation fleet. Additionally, LSA aircraft can now legally be used for compensation or hire in specified aerial work operations.
Perhaps most notably for the maintenance community, MOSAIC also expands privileges for Light-Sport Repairmen. It allows them to perform annual condition inspections on Experimental/Amateur-Built aircraft through a streamlined 16- to 120-hour certification course. This provides a fast and affordable pathway into aviation careers at a time when A&P mechanic shortages are hitting the industry hard.
As the FAA describes it, the rule aims to “increase the availability of safe, modern, and affordable aircraft for recreational aviation, flight training, and certain aerial work operations.”
