FAA Expands LSA Rules With MOSAIC Overhaul

The FAA has finalized the Modernization of Special Airworthiness Certification (MOSAIC) rule, announced by U.S. Transportation Secretary Sean Duffy at the EAA AirVenture airshow. The rule transitions from weight-based to performance-based standards, expanding the Light Sport Aircraft (LSA) category to include fixed-wing, rotary-wing, and future vertical lift aircraft. It permits advanced technologies and allows simplified vehicle operations (SVO), reducing pilot training requirements by up to 50% for eligible aircraft. LSA certificate holders can now repair and instruct on helicopters equipped with SVO, lowering entry barriers for maintenance professionals and pilots. The rule also expands operational privileges and is seen by industry leaders as a transformative modernization that supports safety, innovation, and accessibility. Implementation will be phased in over the coming year.
