The FAA has officially finalized the long-awaited Modernization of Special Airworthiness Certification (MOSAIC) rule, ushering in a new era for recreational and light sport aviation. Announced at EAA AirVenture Oshkosh 2025 by U.S. Transportation Secretary Sean P. Duffy, the MOSAIC rule removes outdated restrictions and expands the Light Sport Aircraft (LSA) category, making it easier than ever for pilots and manufacturers to innovate and grow.
If you’ve been following FAA MOSAIC updates and wondering when will FAA MOSAIC take effect, here’s what you need to know.
What Is MOSAIC?
MOSAIC (Modernization of Special Airworthiness Certification) is a sweeping FAA rule designed to modernize the Light Sport Aircraft category and Sport Pilot privileges. First proposed in July 2023, MOSAIC has been in development for years and received over 1,300 public comments before being finalized.

If you’ve been asking when will FAA MOSAIC be approved or when will MOSAIC go into effect, the wait is over.

Key Changes Under FAA MOSAIC
No More Weight Limit for LSAs
The old 1,320 lb weight limit is gone. Aircraft are now certified based on performance standards, opening the door for safer, more capable designs.
💡 Tecnam’s P2008 leverages these updates with advanced avionics and safety features, making it an excellent option for pilots seeking modern design under MOSAIC.
Four-Seat Aircraft Allowed
LSAs can now have up to four seats, making family flying a possibility for Sport Pilots.
Retractable Gear and Constant-Speed Props
Aircraft with retractable landing gear and constant-speed propellers are now included.
Alternative Propulsion Systems Approved
Electric and hybrid propulsion systems are eligible for LSA certification.
Expanded Sport Pilot Privileges
Sport Pilots can now operate more complex aircraft, fly at night with proper training, and engage in limited commercial operations such as aerial photography, agricultural observation, and infrastructure inspection.
Modern Avionics Permitted
Advanced glass panels and autopilot systems are now part of the LSA framework.

Why This Matters
For pilots, MOSAIC means more options, safer aircraft, and new opportunities to enjoy aviation. For manufacturers, it removes roadblocks to innovation.
As FAA Administrator Bryan Bedford said:
“This landmark rule enables industry to meet the growing demand for more versatile aircraft with higher performance capabilities while maintaining high standards of safety.”
FAA MOSAIC Medical Requirements
Wondering if FAA MOSAIC changes Sport Pilot medicals? The good news: Sport Pilots can still fly with a valid U.S. driver’s license in place of an FAA medical certificate for most operations.
