Circumstances:
On the leg from Kirov to Shurma (without passengers or cargo) of a flight from Kirov to Plotbishche, the crew encountered below minima weather conditions (snowfall and poor visibility) between Urzhum and Shurma and suffered from severe icing. The decision to divert to Kilmez was taken too late so the aircraft went out of control due to icing and crashed in a snow covered field between Shevnino and Sanatorny, some 10 km east of Urzhum Airfield. The aircraft caught fire and burnt out, killing both pilots. The wreckage was found two days later, on December 21.
Probable cause:
Loss of control in flight due to severe icing conditions.

Circumstances:
The crew was cleared to descent to 5,700 meters when a technical issue occurred on the elevator trim system. The airplane entered a dive and during the descent, the captain was able to regain control at an altitude of 2,000 meters. While flying by night, the gyro failed and the pilot suffered a spatial disorientation. So he lost again control of the airplane that dove into the ground and crashed in a near vertical attitude at a speed of 900 km/h in an open field located about 480 meters from Karacharovo. The aircraft disintegrated on impact and all 51 occupants were killed.
Probable cause:
An electrical short-circuit occurred in the elevator trim system, causing the elevator to be jammed in a down position. In such conditions, the airplane entered a dive and became uncontrollable after the gyro failed as well.

Circumstances:
The descent to Domodedovo Airport was initiated by night and marginal weather conditions with limited visibility due to snow falls. On final, the airplane was unstable and not properly aligned on the glide so the captain decided to make a turn to the left when the airplane banked left to 35-40°, causing the left wing to struck the ground 135 meters short of runway threshold and 25 meters to the right of its extended centerline. Out of control, the airplane crashed in flames and came to rest 340 meters past the threshold and 220 meters to the left of the runway. Five crew members and seven passengers were killed while 63 other occupants were injured. The aircraft was destroyed by a post crash fire. Within 10 days after the accident, four other passengers died from their injuries.
Probable cause:
It was determined that the crew adopted a wrong approach configuration in marginal weather conditions and failed to initiate a go-around maneuver while the aircraft was not properly aligned on the glide and was unstable. The sharp turn completed by the captain caused the airplane to become uncontrollable and to crash.

Circumstances:
Following an uneventful flight from Kutaisi, the crew started the descent to Moscow-Domodedovo by night and good weather conditions. On approach at an altitude of 1,300 feet, the airplane banked left to an angle of 75° then nosed down and crashed in a huge explosion in a potatoes field located 16,3 km from the runway threshold. The aircraft disintegrated on impact and all 122 occupants were killed.
Probable cause:
It was determined that the loss of control on approach was the consequence of the failure of artificial horizons as a result of a malfunction of the on-board electrical system. The combination of night, lack of visibility and flight instruments failure caused the pilot to suffer a spatial disorientation and the eventual loss of control.

Circumstances:
The airplane was completing a cargo flight from Yakutsk to Magadan, carrying two passengers, eight crew members and a load of 12 tons of vegetables. The approach to Magadan-Sokol Airport was started by night and marginal weather conditions (rain falls). While descending to an altitude of 570 meters, the captain decided to initiate a go-around when the airplane struck the slope of a snow covered mountain and crashed 13,7 km short of runway. The aircraft disintegrated on impact and all 10 occupants were killed.
Probable cause:
The accident which resulted in a controlled flight into terrain was the consequence of several navigational errors on part of the crew of failed to follow the published procedures. This caused the aircraft to be off course by 5,6 km on approach. The poor visibility due to night and rain falls and the lack of ATC assistance was considered as contributing factors.
