Circumstances:
The aircraft was completing a cargo flight from Moscow to Yakutsk with intermediate stops in Amderma, Khatanga and Magadan, carrying a load of fruits (grapes, pears and lemons) for a total weight of 10,776 kilos. Following an uneventful flight from Sheremetyevo Airport, the crew started the approach to Amderma and was cleared to descent to 600 meters. At high speed, flaps and undercarriage retracted, the airplane was on a straight-in approach when it banked left in a 40° angle and crashed in a prairie located 15 km short of runway. The aircraft disintegrated on impact and debris were found scattered on 540 meters long and 180 meters wide. All 12 occupants were killed.
Probable cause:
The exact cause of the accident could not be determined with certainty. However, it is believed that the accident may have been caused by an excessive accumulation of ice on wings and stabs. Also, it could be possible that the loss of control was the consequence of a technical problem with the autopilot system.
