Circumstances:
During the takeoff roll on runway 27 at Keperveyem Airport, the four engine aircraft deviated to the left, went out of control and veered off runway. It lost its undercarriage and slid before coming to rest 120 metres to the left of the runway and after a course of 880 metres. All 8 occupants escaped uninjured while the aircraft was damaged beyond economical repair.
Probable cause:
Loss of control during takeoff following the failure of the nosewheel steering system due to the malfunction of the VG15-2S switch. The captain failed to check the nosewheel steering system prior to takeoff, which was considered as a contributing factor.

Circumstances:
During the takeoff roll, at a speed of 290 km/h, the copilot started the rotation. The aircraft lifted off, reached a height of 7 metres then entered a left bank of 3,5°. Following a course of 665 metres, the aircraft entered a critical angle of attack, nosed up to 35° then landed back on the runway while the undercarriage have just been retracted. The aircraft slid on its belly and came to rest 270 metres further, about 120 metres to the left of the runway centerline. All 25 occupants were rescued, among them two were seriously injured. The aircraft was damaged beyond repair.
Probable cause:
It was determined that the captain decided to seat on the right front seat, letting the command to the copilot seating in the left front seat, which was against the published procedures because the copilot was not authorized and did not have sufficient experience. The copilot forgot to extend the flaps in an appropriate angle for the takeoff procedure, which caused the aircraft to adopt a critical angle of attack after liftoff and to stall. Successives errors and poor crew coordination were considered as contributing factors as well as the fact that the crew failed to follow the pre-takeoff checklist and failed to identify that the aircraft was not properly configured for the takeoff procedure.

Circumstances:
The aircraft departed Cape Schmidt on a special flight to Pevek consisting of a survey mission of the ice drifting in the Chukotka Sea. While approaching the coast at a height of 100 meters, the pilot initiated a turn to the right to 270° when the aircraft struck the rocky face of a mountain (145 meters high) overhanging the sea. The aircraft disintegrated on impact and all 10 occupants were killed.
Probable cause:
For unknown reasons, the crew was approaching the coast at an insufficient altitude. At the time of the accident, the visibility was limited so the crew was unable to see and avoid the mountain. It was determined that the turn to 270° was initiated 1,2 km from the coast while this procedure should be completed 10 km away from the coast. In such conditions, impact with the ground was unavoidable.
