Key Takeaways:

The FAA introduced the Modernization of Special Airworthiness Certification (MOSAIC) rule, significantly expanding the Light Sport Aircraft (LSA) category to include more diverse aircraft like two-seat VTOLs and electric models, replacing rigid weight limits with performance-based criteria, and enhancing sport pilot privileges.
The FAA also published an Advisory Circular (AC) outlining a clear certification blueprint for larger, commercial electric Vertical Takeoff and Landing (eVTOL) aircraft, categorized as "powered-lift," streamlining their path to type, production, and airworthiness approval.
These new regulations provide crucial clarity and a more predictable pathway for the certification and operation of advanced air mobility (AAM) aircraft, fostering innovation and accelerating the industry's progression towards commercial services.

The introduction of electric, vertical takeoff and landing (VTOL), and other advanced air mobility (AAM) aircraft into U.S. national airspace has raised plenty of questions, not least of which is how they will be certified and operated. The FAA is finally beginning to answer them.

The publication of a final Modernization of Special Airworthiness Certification (MOSAIC) was a highlight of this year’s EAA AirVenture in Oshkosh, Wisconsin. Sport pilots will likely be familiar with the rule’s major changes—namely, the replacement of rigid weight and seating limits with performance-based criteria, and expanded privileges, such as flying at night.
