Design and development

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 95 hp (71 kW) Hirth F-30 engine.[1]

The aircraft fuselage is made from composites. Its 23.00 ft (7.0 m) 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.[1][2]

The aircraft has an empty weight of 495 lb (225 kg) and a gross weight of 1,085 lb (492 kg), giving a useful load of 590 lb (268 kg). With full fuel of 16 U.S. gallons (61 L; 13 imp gal) the payload for crew and baggage is 494 lb (224 kg).[1]

The manufacturer estimated the construction time from the supplied kit as 60 hours.[1]

Operational history

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]
