Circumstances:
The airplane departed Tyumen Airport at 0805LT on a special flight to Sverdlovsk, carrying three crew members and seven passengers on their way to a political party committee meeting. A little more than an hour into the flight, while cruising at an altitude of 100 metres in good weather conditions, the left engine failed. The pilot lost control of the airplane that rolled to the left then entered a dive and crashed 1,5 km from the village of Chernokorova, bursting into flames. The airplane was totally destroyed and all 10 occupants were killed.
Probable cause:
Loss of control in flight following the failure of the left engine for undetermined reasons.
