Avio Design Swan

The Avio Design Swan is a family of Bulgarian ultralight trikes, designed and produced by Avio Design of Kazanlak. The aircraft are all supplied as a complete ready-to-fly-aircraft.

Design and development
The aircraft family was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg. All models feature a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit, tricycle landing gear with wheel pants and a single engine in pusher configuration.

The aircraft is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth. Typical wings used have a 9.5 to 10.2 m span wing, are supported by a single tube-type kingpost and use an "A" frame weight-shift control bar. The standard powerplant is the twin cylinder, air-cooled, two-stroke, dual-ignition 64 hp Rotax 582 engine. Options do not include the 80 hp Rotax 912 engine.
