[2] On 11 December 1953, the Soviet Council of Ministers issued directive No.2922-1251 to the Antonov OKB, requiring them to build a twin-turboprop transport aircraft derived from the DT-5/8.
[4] The Antonov OKB set about rectifying these faults with increased-area vertical and horizontal tail surfaces, anti-spin strakes on the upper rear fuselage sides, deleting the wing leading-edge slats, adding local structural reinforcements and replacing the TV-2 engines with Ivchenko AI-20D turboprop engines, which had the added benefit of reducing the empty weight by 3 tonnes (6,600 lb).
[4] Given the service designation An-8, the new transport was built in the GAZ-34 factory in Tashkent from 1957 to 1961, as a larger-capacity replacement for the earlier Lisunov Li-2 (DC-3), with a large unpressurized hold, a manned tail gun position, chin radome for navigation/mapping radar and a glazed nose for the navigator.
[4] The first production aircraft was rolled out in December 1958 incorporating de-rated AI-20D engines, (the initial production AI-20D was found to be incapable of delivering the specified power), modified undercarriage control systems, fuel vents, pressurization and de-icing systems, as well as thicker gauge skin in the propeller plane of rotation and increased rudder range of movement.
This did not mean the end of the An-8, however as a number were sold overseas with a few aircraft observed flying in the Middle East and in Africa, particularly Liberia, DR Congo and Angola until around 2010, (especially airlines associated with the Russian businessman and convicted arms dealer Viktor Bout),[5][7] despite Antonov having withdrawn the airworthiness certificate and support for the type in 2004, ending legal use of the aircraft.
