The four engine aircraft departed Yuzhno-Sakhalinsk Airport on a cargo flight to Ermolino with two intermediate stops in Ust-Ilimsk and Omsk, carrying 14 passengers, 9 crew members, 8,6 tons of fish, 2 cars and 2 minibuses. The approach to Ust-Ilimsk Airport was completed by night and poor weather conditions (icing conditions) with a visibility below minima due to low clouds. On short final, the aircraft nosed down and crashed on the top of a hill located 2,1 km short of runway. The aircraft was destroyed and all 23 occupants were killed.
