The Antonov An-24 is a 50-seat twin turboprop regional airliner designed in 1957 in the Soviet Union by the Antonov Design Bureau. Later variants saw other uses, such as military transport and aerial cartography. The aircraft was manufactured by the Kyiv, Irkutsk and Ulan-Ude Aviation Factories. It is still license-produced in China as the Xi'an Y-7.
