The An-12 operated on a cargo flight with a 10,475 kg of grapes from Tashkent to Yuzhno-Sakhalinsk. En route stops were planned in Fergana, Novosibirsk, Krasnoyarsk and Irkutsk. During the leg from Krasnoyarsk to Irkutsk, the airport at Irkutsk was reported closed due to poor weather.
The crew decided to divert to Ulan-Ude although that airport was not prepared to handle An-12s. The crew did not set QNH for Ulan-Ude on approach, causing false altitude readings. The aircraft crashed at a height of some 1,200 metres into a wooded mountain slope 32 km north-west of Ulan-Ude.
