Antonov An-10

The Antonov An-10 Ukraina, NATO reporting name Cat, is a four-engined turboprop passenger transport aircraft designed in the Soviet Union for routes of 500 to 2,000 kilometres. Antonov derived it from the passenger version of the An-8, giving it a larger circular-section pressurised fuselage, and chose Ivchenko AI-20 engines partly because the Communist Party of Ukraine wanted as much production as possible in Ukraine. The first prototype flew on 7 March 1957, a taller fin and auxiliary tailplane fins cured poor directional stability, and Aeroflot began services on 22 July 1959 on the Moscow to Simferopol route. A total of 104 aircraft were built, and the later An-10A raised seating from 85 to as many as 132, but Aeroflot retired the type after an accident, which effectively ended its career.
