Circumstances:
The crew departed Ulan-Ude-Mukhino Airport on a local training flight. Following several circuits, it was decided to shut down an engine to simulate a failure. After the propeller was feathered, the flight engineer mistakenly shut down the second engine. The crew completed a belly landing on the Bodorodski Island located about 8 km short of runway 26. The aircraft was partially consumed by a post crash fire and all crew members were slightly injured.
Probable cause:
Engine mistakenly shot down by the flight engineer during a single engine exercise.

Circumstances:
On an unauthorized pleasure flight before sunrise during crop-spraying operations for the sovkhoz (state farm) at Tuma (Spas-Klepiki district of the Ryazan region), the intoxicated crew (the alcohol content of the captain's blood was 3.3 ‰) performed unauthorized manoeuvre at low height and lost control of the aircraft that crashed in a wooded area located 3 km southeast of Malakhovo. The aircraft caught fire and burnt out. Both pilots and the sole passenger were killed.
Probable cause:
Intoxicated crew.

Circumstances:
The airplane was completing a cargo flight from Yakutsk to Batagay, carrying a crew of six, two passengers and a load of pipes for a total weight of 11,350 kilos. Following an uneventful flight and approach, the crew completed the landing in good conditions. According to the crew and eyewitnesses, the touchdown was smooth about 74 meters past the runway threshold at a speed of 250 km/h. After a course of 105 meters, a loud sound was heard on the right side of the aircraft. While decelerating, the aircraft deviated to the right when, at a speed of 210 km/h, the engine n°4 struck the ground. The airplane veered off runway to the right, struck an earth mound then trees, pivoted on itself before coming to rest in flames 710 meters after the initial impact and 30 meters to the right of the runway. All eight occupants evacuated safely while the aircraft was damaged beyond repair.
Probable cause:
The right main landing gear leg broke shortly after touchdown, probably due to fatigue fracture. Investigations were unable to accurately define the landing parameters because the aircraft was not equipped with the latest generation of FDR systems. The failure of the right main gear could be explained by a prolonged operation of the aircraft under very low temperatures with a large number of landings completed with a total weight at the limit of tolerances. Also, the fact that the flaps were deployed at 25° upon landing resulted in a speed increase of approximately 20 km/h compared to a landing configuration with flaps extended at 35°, which could also be considered as a contributing factor.

Circumstances:
Following seven approaches and landings completed successfully, the crew started a eighth approach in good weather conditions. On final, the instructor thought that the admission pressure on the right engine dropped so he decided to shut down the engine and to feather its propeller without communicating with the rest of the crew. To compensate the loss of power, he asked the flight engineer to increase power on the left engine but the flight engineer inadvertently shot down the left engine when the right engine was just shot down as well. In such conditions, the pilot-in-command attempted an emergency landing when the airplane crash landed in a field located near Bykovo Airport. The aircraft was damaged beyond repair and three crew members were injured.
Probable cause:
The accident was the consequence of the combination of the following factors:
- Poor flight preparation,
- Lack of crew coordination,
- Lack of interaction between the instructor and the rest of the crew,
- Irresponsible actions on part of the flight engineer.

Circumstances:
After takeoff from Norilsk Airport on a flight to Vorkuta by night, the crew was informed by ATC that a landing in Vorkuta was not possible due to poor weather conditions and a below-minima visibility. The crew was diverted to the Sovetskiy AFB located east of Vorkuta and also know as Vorkuta-2 Airport. In poor visibility and crosswinds, the airplane landed 15 metres to the left of the snow covered runway, crashed into the snow and came to rest, broken in two. All five crew members were unhurt while the aircraft was written off.
Probable cause:
Approach to a poor equipped airfield below minima weather conditions.

Circumstances:
The airplane was completing a cargo flight from Tyumen to Surgut, carrying one passenger, six crew members and a load of 12 tons of herring from the Pacific. On final approach by night, at an altitude of 400 meters and a speed of 330 km/h, the captain requested 'flaps 15' when the airplane became unstable and rolled left and right. Few seconds later, the airplane entered a nose down attitude, reached the speed of 395 km/h and crashed in a left bank of 90° into an icy lake located 13,6 km from the runway threshold. The aircraft was totally destroyed and all sven occupants were killed.
Probable cause:
Loss of control caused by an excessive accumulation of ice on wing tips. The following factors were considered as contributing:
- Severe icing conditions,
- Misuse of the de-icing systems by the crew, especially with regard to air bleeding of the engines.

The aircraft was completing a cargo flight from Omsk to Surgut, carrying two passengers, a crew of 12 (among them six reserve members) and a load of 12 tons of various construction equipments. While approaching Surgut Airport by night and icing conditions, at an altitude of 400 meters and a speed of 330 km/h, the pilot lost control of the airplane that crashed in flames 15 km short of runway. The aircraft was destroyed and all 14 occupants were killed.
Probable cause:
There were severe icing conditions at the time of the accident and the crew activated all de-icing equipment. Nevertheless, it appears that following the failure of a valve, the de-icing equipment was inoperative. An excessive accumulation of ice on the fuselage, the wings and all four engines caused the loss of control.

The crew managed to land safely at Rostov-on-Don, but the aircraft suffered structural damage during the dive with up to 3.5 g forces, and was damaged beyond repair. There were no casualties. SOC 29sep71 as worn out.
Probable cause:
Loss of control in flight caused by a probable failure of the autopilot system.
