The OneAircraft One is a Slovenian light-sport aircraft (LSA) and certified light aircraft designed by Iztok Šalamon and produced by OneAircraft (One Pro, d.o.o.) of Celje. The aircraft is supplied complete and ready-to-fly.[1][2]

OneAircraft was founded in 2014 as a joint venture between C2P d.o.o. and Kops pro d.o.o.[2]

Design and development[edit]

The One was designed to comply with the US LSA rules as a two-seater and the European rules as a certified 3-4 seat EASA CS-VLA category aircraft. It features a cantilever low-wing, an enclosed cabin with two-seats-in-side-by-side configuration or four seats, all accessed by doors, fixed tricycle landing gear and a single engine in tractor configuration.[1]

The aircraft is made from carbon fibre and uses the wings and tail surfaces derived from the Shark.Aero Shark. Its 9.67 m (31.7 ft) span wing mounts flaps. The horizontal stabilizer is low-mounted. The standard engine used is the 100 hp (75 kW) Rotax 912ULS, four-stroke powerplant.[1]

The company has indicated that they expect LSA acceptance in 2017, but as of March 2017, the design does not yet appear on the Federal Aviation Administration's list of approved special light-sport aircraft.[3][4]
