Circumstances:
On final approach to Novosibirsk-Tolmachevo Airport, the crew encountered poor weather conditions and the captain decided to go around. A second attempt to land was made few minutes later. As the visibility seems to improve a bit, the captain decided to land. After touchdown on a waterlogged runway, the airplane was unable to stop within the remaining distance and overran. While contacting soft ground, the undercarriage were sheared off and the airplane came to rest. There were no casualties.
Probable cause:
The assumption that the accident was caused by an aquaplaning effect or an excessive speed upon landing was not ruled out.

Circumstances:
The crew was on a positioning flight from Cheremshan to Kazan after he completed crop spraying operations in the region of Cheremshan. After takeoff, while climbing to a height of 25 meters, the airplane banked 50° then stalled and crashed in flames in a field located 160 metres outside of the airfield's perimeter. A pilot and the passenger were killed while three other occupants were injured. The aircraft was destroyed.
Probable cause:
It was determined that the intoxicated crew flew unauthorized manoeuvre at low height shortly after lift-off. Control was lost.

Circumstances:
Due to technical issues with the on board heating system, the departure from Dhzigda was postponed after sunset. Despite the poor visibility, the pilot decided to takeoff around 2030LT and after liftoff, the airplane continued at low height and turn slightly to the right when control was lost. The airplane banked right to an angle of 25° then stalled and crashed at a speed of 220 km/h in a wooded area located 3,5 km from the airfield. The wreckage was found two days later and all three occupants were killed.
Probable cause:
It was determined that the pilot lost control of the aircraft after he suffered a spatial disorientation. It was also noted that he took the decision to takeoff by night with an aircraft which was not equipped for night flight. Both departure and destination airport were not suitable for night operations as well. It is possible that the pilot's capabilities were reduced due to the low temperature on board as the heating system was inoperative. Thus, the assumption that the artificial horizon was unserviceable due to low temperature was not ruled out.

Circumstances:
The crew was engaged in a local night training mission at Batagay Airport. Following three uneventful circuits, the crew started a fourth approach in a visibility reduced to 4 km due to snow showers. On final, the aircraft struck the slope of a snow hill located 2,200 meters short of runway and 205 meters to the right of its extended centerline. The aircraft was destroyed and both pilots were killed. Shortly before the accident, the visibility dropped from 7 to 4 km.
Probable cause:
Poor flight preparation on part of the flying crew who conducted the training mission without the appropriate flying charts. Lack of assistance on part of the ATC at Batagay Airport Tower who failed to transmit information about the deterioration of the weather conditions.

All four occupants were uninjured and there were no victims on the ground.

Circumstances:
The crew was returning to Irkutsk following a cargo flight to Mirnyy. After takeoff from Kirensk Airport, while climbing to a height of some 500 meters, the airplane banked left, dove into the ground and crashed onto a wooden hut located 750 meters south of the airfield. The airplane was totally destroyed and all six crew members were killed.
Probable cause:
It was determined that both left engine lost power shortly after takeoff and progressively failed during climb. The crew elected to feather the propeller but without success. The airplane then banked to the left and crashed at an angle of 70°. Investigations were unable to determine the exact cause of the engine failure but the assumption of an electrical short-circuit or an excessive accumulation of ice in the fuel filter was not ruled out.

Circumstances:
During the takeoff roll, at a speed of 130 km/h, the pilot-in-command started the rotation. The airplane climbed few meters but was unable to gain sufficient height and banked right to an angle of 20°. The crew tried to regain control but the airplane was totally unstable. The pilot decided to reduce the power on left engine then on right engine when the airplane crash landed past the runway end. All six crew members were uninjured while the aircraft was damaged beyond repair.
Probable cause:
Poor flight preparation on part of the crew. Prior to departure, the airplane was refuelled but the fuel quantity was too high and the total weight of the aircraft at takeoff was 12,140 kilos, about 640 kilos above the MTOW. Also, it was determined that the cargo shifted in the cabin at liftoff and struck the lateral door, modifying the CofG by 22% and causing the aircraft to be uncontrollable.

Circumstances:
The airplane departed Baku Airport at 1408LT on a cargo flight to Dnipropetrovsk, Ukraine, carrying two engineers from the motorist Zaporozhie, four crew members and a load consisting of five gear boxes for a total weight of 1,366 kilos. After takeoff from Baku, the airplane climbed to an altitude of 2,100 meters and the crew obtained the permission to modify his route to make an intermediate stop at Rostov-on-Don before continuing to Dnipropetrovsk. Doing so, the crew failed to request information about weather conditions en route. Later into the flight, weather conditions worsened and the captain requested the permission to descend to 1,500 meters but this was not possible and ATC instructed the crew to maintain the assigned altitude of 2,100 meters. While cruising in a thunderstorm, the airplane went out of control, partially disintegrated in the air and eventually crashed in a field located 10 km north of Izobilnoye. The aircraft was totally destroyed and all six occupants were killed. It was reported that the left stabiliser was the first part to be sheared off during the descent and was found 850 meters from the main wreckage.
Probable cause:
Loss of control caused by severe downdrafts and turbulences while cruising in a thunderstorm activity. It was reported that the crew has not been informed about the deterioration of the weather conditions.

Circumstances:
The airplane departed Nagurskoye Airport, in the Franz-Josef Archipelago, at 0820LT with a crew of five and two hydrologists on board to perform an ice reconnaissance to allow the launch of the icebreaker 'Indigirka'. While flying at an altitude of 150 meters in a visibility less than one km, the aircraft struck the southwest slope of the Graham Bell Glacier, flew for 750 meters before crashing in flames. The aircraft was destroyed and all seven occupants were killed. At the time of the accident, the visibility was below minima.
Probable cause:
Failure of the crew to follow the published procedure while cruising at an insufficient altitude in limited visibility (below minima). Due to a conception issue, the on-board weather radar failed to detect the mountain.

Circumstances:
The aircraft departed Kostroma Airport at 0730LT with one passenger and seven crew on board. They were in charge to make aerial photography of the railroad from Neya to Svesha via Manturovo and Sharya. After two hours and ten minutes of flight, the left engine failed. The captain decided to divert to Sharya when the right engine overheated shortly later. In such conditions, he decided to attempt an emergency landing when the airplane lost height, struck trees and crashed in a dense wooded area located on km 711, some 600 meters from the railroad. The passenger was unhurt while all seven crew members were injured. Eighteen hours later, the captain died from his injuries. The airplane was destroyed.
Probable cause:
Failure of the left engine in flight due to the dysfunction of the carburetor. The high outside temperature was considered as a contributing factor as the crew was unable to maintain a safe altitude on one engine in such conditions.
