kg) or 1,430 lbs for seaplanes (650 kg) Max. stall speed: CAS Max. speed in level flight (at sea level In the U.S. Standard Atmosphere): CAS Max. seats: two Max. engines / motors: one (if powered) Propeller: fixed-pitch or ground adjustable Cabin: unpressurized Fixed-pitch, semi-rigid, teetering, two-blade rotor system, if a gyroplane. Landing gear: fixed (except for seaplanes and gliders) Aircraft licensing Can be manufactured and sold ready-to-fly under a new special light sport aircraft certification category. Aircraft must meet industry consensus standards. Aircraft under this certification may be used for sport and recreation, flight training, and aircraft rental. Can be licensed experimental light sport aircraft (E-LSA) if kit- or plans-built. Aircraft under this certification may be used only for sport and recreation and flight instruction for the owner of the aircraft. Can be licensed experimental light sport aircraft (E-LSA) if the aircraft has previously been operated as an ultralight but does not meet the FAR Part 103 definition of an ultralight vehicle. These aircraft must have been transitioned to E-LSA category no later than January 31, 2008. Will have a standard FAA registration - N-number. Category and class includes: airplane (land/sea), gyroplane, airship, balloon, weight-shift-control ("trike", land/sea), glider, and powered parachute. U.S. or foreign manufacture of light sport aircraft is authorized. Aircraft with a standard airworthiness certificate that meet above specifications may be flown by sport pilots. However, the aircraft must remain in standard category and cannot be changed to light sport aircraft category. May be operated at night if the aircraft is equipped per FAR 91.205, if such operations are allowed by the aircraft's operating limitations and the pilot holds at least a private pilot certificate and a minimum of a third-class medical. FAA certification Several different kinds of aircraft may be certificated as LSA. Airplanes (both powered and gliders), rotorcraft (gyroplanes only, not helicopters), powered parachutes, weight-shift control aeroplanes (commonly known as trikes), and lighter-than-air craft (free balloons and airships) may all be certificated as LSA if they fall within the weight and other guidelines established by the local governing authority. The US definition of an LSA is similar to some other countries' definition of "microlight" or "ultralight" aircraft. Except for the LSA's relatively generous MTOW of 1320 pounds, the other countries' microlight definitions are typically less restrictive, not limiting airspeed or the use of variable-pitch propellers. By contrast, the US FAA has a separate definition of
