Countdown to FAA’s MOSAIC Phase 2: A Major Shift in General Aviation Regulations
General aviation stands on the brink of its most significant regulatory transformation in over two decades. Phase 2 of the FAA’s MOSAIC rule (Modernization of Special Airworthiness Certification) is set to take effect on July 24, 2026 — a mere six weeks away.
The groundbreaking rule, finalized in July 2025 and first unveiled at EAA AirVenture Oshkosh 2025, supersedes the outdated 1,320-pound maximum takeoff weight limit for light-sport aircraft. It introduces performance-based stall-speed criteria, paving the way for a wider and more capable range of aircraft. On July 24, the term “Light Sport Aircraft” will officially be replaced in FAA regulations with the new designation “Light-Sport Category Aircraft.”
Under the new regulations, sport pilots — given the appropriate endorsements — will have the ability to fly aircraft with up to four seats and superior performance characteristics. This includes select models such as the Cessna 182 and Piper Archer that meet the new stall-speed criteria, although they are still restricted to carrying one passenger. The rule also provides new certification avenues for manufacturers, permitting advanced avionics, electric propulsion, turbine engines, gyroplanes, and powered-lift aircraft to join the light-sport category.
Aviation organizations such as AOPA, EAA, and the FAA are encouraging pilots and owners to thoroughly review the changes before the July deadline. Comprehensive details and FAQs are accessible at FAA.gov/aircraft/MOSAIC.
