Sukhoi Su-80

The Sukhoi Su-80, formerly the Sukhoi S-80, is a Russian twin-turboprop, twin-boom STOL transport aircraft, meant to replace the An-24/26, An-28 and Yak-40 and to compete with the Antonov An-38. Lack of funds delayed the programme from the late 1990s, and the prototype first flew on 4 September 2001 with Igor Wotinzew at the controls. In early 2006 the type entered production at the KnAAPO factory in Komsomolsk-on-Amur. The layout, with three lift-generating surfaces, resembles the Scaled Composites ATTT and the Rockwell OV-10, and the fuselage has space for 30 passengers and a beaver-tail cargo ramp at the rear. Several airlines and air forces signed preliminary agreements or expressed interest, but no aircraft performed active service.
