Key Takeaways:

The FAA's new MOSAIC rulemaking proposal aims to revolutionize the light sport aircraft (LSA) market by removing current weight limits and introducing performance-based criteria, significantly increasing LSA usefulness and opportunities for sport pilots.
Key proposed changes define fixed-wing LSA by a clean stall speed of 54 knots, a maximum flight level speed of 250 knots, and up to four seats, though sport pilots remain limited to one passenger.
The proposal has garnered widespread support from major general aviation groups (EAA, AOPA, SAFE) and manufacturers (Zenith, Pipistrel), who anticipate enhanced affordability, capability, and new design choices, including electric propulsion.
