A41 Factory VNS-41

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. A Che-22 was acquired by Vietnam in the late 1990s and from the Philippines. Technicians began developing the VNS-41 in June or July 2003. On 12 September 2004, the prototype performed its maiden flight with test pilot Nguyễn Duy Lê at the controls.

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 l/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 m run. Meanwhile, the VNS-41 can take off on water after a 200–300 m run. The cost of the aircraft is under two billion Vietnamese đồng.

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