Key Takeaways:

The FAA's new Modernization of Special Airworthiness Certification (MOSAIC) rule significantly updates the light sport aircraft (LSA) category and sport pilot privileges.
The rule removes the existing weight limit for LSAs, allowing for faster, heavier, and more capable designs, including aircraft with up to four seats, retractable landing gear, constant-speed propellers, and alternative propulsion systems.
Sport pilot privileges are expanded to include night flying, operating more complex aircraft (such as helicopters and powered-lift), and performing limited commercial activities like aerial photography or agricultural observation.
