The aircraft was completing a cargo flight from St Petersburg to Nalcik with an intermediate stop in Volgograd, carrying seven passengers, six crew members and a load of 12,5 tons of coins minted in St Petersburg. On final approach, at a distance of 8 km from the airport, at a speed of 260 km/h, flaps were selected down to an angle of 35°. Thirty seconds later, the aircraft started to pitch up and down then nosed up to an angle of 15°. It entered an uncontrolled descent and crashed at a speed of 414 km/h in a nose down angle of 55° in an open field located 4,5 km short of runway threshold. The aircraft disintegrated on impact and all 13 occupants were killed.
Probable cause:
It was determined that the loss of control was the consequence of an excessive accumulation of ice on stabilizers. Information transmitted to the crew regarding weather conditions at destination did not reflect the actual situation and did not mention any icing conditions.

Circumstances:
Following an uneventful flight from Nalcik, the crew started the descent to Leninabad Airport when he encountered limited visibility due to low clouds. At an altitude of 3,300 meters and following several navigational errors, the aircraft deviated from the prescribed flight path by 29 km. On his side, the ATC controller was unable to determine the exact position of the aircraft and cleared the crew to descent to 900 meters. While descending at an altitude of 2,523 meters at a speed of 330 km/h, the three engine airplane struck the slope of Mt Shishtepe (2,836 meters high) located about 40 km from Leninabad Airport. The aircraft disintegrated on impact and all 21 occupants were killed.
Probable cause:
The airplane deviated from the prescribed flight path following several navigational errors on part of the flying crew. Poor ATC assistance was considered as a contributing factors as he cleared the crew to descent to the altitude of 900 meters despite he was unaware of the exact position of the aircraft. Poor flight preparation, poor approach planning and lack of crew coordination were also considered as contributing factors.
