The Fly-Fan Shark is a Slovak light aircraft designed by Frantisek Sustek and initially developed by Fly-Fan of Trenčín. Development continues under the new owner of the design, AENEA Services. The design was introduced at the AERO Friedrichshafen show in 2007 as a mock up and in 2011 as a flying aircraft. The aircraft first flew on 29 June 2011 and is intended to be supplied as a complete ready-to-fly-aircraft.^[1]^[2]^[3]^[4]

Design and development

The Shark was designed with the goal of providing similar performance to other twin-engined light aircraft, but on 30% less power. It features a cantilever low-wing, a five-seat enclosed cabin, retractable tricycle landing gear and twin wing-mounted engines in tractor configuration.^[1]^[3]

The aircraft is made from Kevlar and carbon fibre. Its 11.4 m (37.4 ft) span wing employs a Jd 16 (40) 162 airfoil at the wing root, transitioning to a Jd 17 (40) 157 at mid-span and a Jd 15 (35) 136 at the wing tip. The wing has an area of 16.2 m² (174 sq ft) and mounts split flaps that can be extended 50°. The standard engines fitted are a pair of 160 hp (119 kW) Lycoming O-320-D1A four-stroke powerplants.^[1]^[3]^[5]

The aircraft has an empty weight of 1,221 kg (2,692 lb) and a gross weight of 1,500 kg (3,300 lb), giving a useful load of 279 kg (615 lb).^[1]
