The VNS-41 is the first amphibious microlight aircraft made in Vietnam. The A41 Factory (officially Aircraft Repair Company A-41) under the Air Force and Air Defence Department (Ministry of Defence) manufactured the aircraft based on the Russian Che-22 Korvet design by Boris Chernov and E. Yungerov.[1] A Che-22 was acquired by Vietnam in the late 1990s and from the Philippines.[2] Technicians began developing the VNS-41 in June[3] or July 2003.[1] On 12 September 2004, the prototype performed its maiden flight with test pilot Nguyễn Duy Lê at the controls.[4]

Fitted with two 65 hp Rotax 582 engines, the VNS-41 used the A92 fuel type, and each of its engines consumed about 19–22 litres per hour (5.0–5.8 gal/h; 19,000–22,000 cm3/h). The VNS-41's hull, tail, and middle wing are made from high-quality composite material. On land, the aeroplane can take off after a 50–70 metres (160–230 ft) run. Meanwhile, the VNS-41 can take off on water after a 200–300 metres (660–980 ft) run. The cost of the aircraft is under two billion Vietnamese đồng.[5]

The VNS-41 will initially be used in forestry patrol and agriculture but will also be marketed for sport, travel and commercial applications.[3][5]
