The Ultrasport 496 is a two-seat trainer development of the Ultrasport 254 and, like that model, is named for its empty weight in pounds. The aircraft was designed to comply with the US Experimental - Amateur-built aircraft rules. It could also have been registered as a FAR 103 Ultralight Vehicles rules exemption trainer. It features a single main rotor, a two-seats in side-by-side configuration enclosed cockpit with optional doors, skid-type landing gear and a four-cylinder, horizontally opposed, air-cooled, two-stroke, dual-ignition 950NaN0 Hirth F-30 engine.
The aircraft fuselage is made from composites. Its 231NaN1 diameter two-bladed rotor employs an ATI 012 (VR-7 mod) airfoil at the blade root, transitioning to an ATI 008 (VR-7 mod) airfoil at the tip. The dual controls include cyclic controls mounted from the cockpit ceiling, but are otherwise conventional. The tail rotor is ring-mounted and the horizontal tailplane mounts end-fins for directional stability. A ballistic parachute was a factory option.[2]
The aircraft has an empty weight of 4950NaN0 and a gross weight of 10850NaN0, giving a useful load of 5900NaN0. With full fuel of the payload for crew and baggage is 4940NaN0.
The manufacturer estimated the construction time from the supplied kit as 60 hours.
In June 2014 one example was registered in the United States with the Federal Aviation Administration, although a total of seven had been registered at one time.[3]
