FAA Unveils Significant MOSAIC Rule Update for Light Sport Aircraft
The Federal Aviation Administration (FAA) has recently introduced its much-anticipated MOSAIC (Modernization of Special Airworthiness Certification) rule. This marks a significant shift in light sport aircraft regulations, the most substantial since 2004. The announcement was made at the EAA AirVenture on July 22. The final rule effectively eliminates the existing weight restrictions for Light Sport Aircraft (LSAs), replacing them with performance-based criteria. This allows for the creation of faster, heavier, and more capable aircraft designs.
Under these new regulations, aircraft featuring up to four seats, retractable landing gear, constant-speed propellers, and alternative propulsion systems (including electric power) will now be eligible for LSA certification. “This landmark rule aims to increase the availability of safe, modern, and affordable aircraft for recreational aviation, flight training, and certain aerial work,” stated FAA Administrator Bryan Bedford.
The MOSAIC rule is strategically designed to encourage wider adoption of factory-built LSAs. It offers enhanced capability while maintaining safety standards. The final rule reflects changes made in response to over 1,300 public comments submitted after the proposal was issued in July 2023.
