Circumstances:
The crew was completing a local training flight at Vitebsk. On approach, a technical problem occurred on the left flap that retracted. The airplane banked left then dove into the ground and crashed about 12 km from the airport. All seven crew members were killed.
Probable cause:
It was determined that a cog-wheel on the left flap broke on approach, causing an uncommanded retraction of the flap. Due to an asymmetric flaps deployment, control was lost.

Circumstances:
The approach to Vitebsk was initiated in icing conditions when the crew lost control of the airplane that lost height, struck power cables and crashed in flames in an open field. Five passengers survived while 26 other occupants were killed. The airplane was enroute from Pskov to Vitebsk, carrying officers taking part to an exercise.
Probable cause:
It is believed that the accident was the consequence of an excessive accumulation of ice on wings, stabs and all fuselage while completing an approach in severe icing conditions while the different deicing systems had apparently not been switched ON by the crew.

Circumstances:
The crew was performing a flight from Irkutsk-2 to Vitebsk with an intermediate stop at Belaya AFB located 85 km northwest of Irkutsk. Shortly after takeoff, while climbing, the aircraft went out of control and crashed in a huge explosion. All ten occupants, four engineers and six crew members, were killed.
Probable cause:
The exact cause of the accident could not be determined with certainty. However, the assumption that the loss of control was caused by the failure of an aileron or a in-flight fire was not ruled out.

Circumstances:
During the takeoff roll, both right engines number three and four failed. Simultaneously, the rudder went to a full left position when the crew attempted to rotate. The aircraft lifted off and then banked right, causing the right wing to struck the ground. Out of control, the aircraft crashed and eventually came to rest in flames, upside down, some 160 meters farther. Six crew members were killed while the gunner was slightly injured.
Probable cause:
Failure of both right engines number three and four due to a short-circuit in a terminal strip. For unknown reason, the crew failed to feather the propeller on both right engines.
