There is a high chance that the long-waited Modernization of Special Airworthiness Certification (MOSAIC) rule of FAA may come out during the Airventure of EAA in Oshkosh MI this week.

This groundbreaking rule will significant expand the scope of the current light sport airplane (LSA) category and will likely redefine the light aircraft market landscape. According to the draft of MOSAIC released last year the new rule may include eVTOL, helicopter, gyrocopter, and heaiver and faster conventional airplanes and may grant more priviledge to sport planes and sport pilots.

MOSAIC shifts from prescriptive limits (like the 1,320 lb weight cap) to performance-based criteria. A maximum clean stall speed (around 54 knots, possibly up to 58 knots) will be the defining factor of the maximum weight. Under MOSAIC, LSA features previously prohibited will be allowed, such as:

• Higher speeds (up to ~250 knots)
• Adjustable-pitch propellers
• Retractable landing gear
• Up to four seats (sport pilots remain limited to one passenger)

Sport pilots may also gain additional privileges through instructor endorsements, including operations in controlled airspace (requiring at least a medical certificate) and night flying.

Stay tuned for the more update of MOSAIC news. There may be a breaking news very soon!
