Aircraft flight hours:
The crew left Verknyaya Salda in the morning on a cargo flight to Ufa. En route, he encountered poor weather conditions and the visibility was reduced by snow falls. As the crew did not have the appropriate charts for the region, he obtained the assistance of the ATC and was vectored to Tyumen Airport. Few minutes later, while cruising at an assigned altitude of 2,100 meters, the central engine lost power and failed. Shortly later, both other engines (left and right) lost power and produced black smoke. In such conditions, the crew was unable to maintain a safe altitude and the captain decided to make an emergency landing. The aircraft hit tree tops and crashed in a wooded area located 14 km north of Mezenka. Four crew members were injured while the captain was killed.
It was determined that all three engines lost power and eventually failed due to an excessive accumulation of wet snow in the carburetor and the air intake.
