Circumstances:
One hour and 35 minutes after its departure from Kuybyshev Airport, bound for Sverdlovsk, the oil pressure on the left engine dropped and the crew decided to shut it down and to feather the propeller. The captain decided to divert to Ufa for a safe landing but due to low clouds, he was unable to locate the airport. When the aircraft broke through the cloud layer, it was in fact above the city and when the crew increased power on the right engine, it failed because it overheat. In such conditions, the captain made a turn to leave the area and continued to the Belaya River to attempt an emergency landing. Eventually, the aircraft hit tree tops and crashed in flames in a wooded area near the river bank, killing all seven occupants.
Probable cause:
Wrong decision on part of the crew who cut the wrong engine after failure.

Circumstances:
During the last segment, while at a height of 10 meters, the crew reduced power on both engines when a fire erupted on the left wing. The pilot in command completed the landing and after touchdown, made an emergency brake procedure. When the aircraft came to a halt, all 16 occupants were able to evacuate the cabin and were unhurt. The aircraft burnt for about 12-14 minutes and was destroyed by fire.
Probable cause:
It was determined that the person in charge to refuel the aircraft in Ashgabat Airport failed to properly close the left fuel tank cap. This was possible because the fuel filter was not correctly set in the fuel line. This led fuel to leak in flight and on approach, the fuel spilled along the wing root, over the wing and eventually caught fire while in contact with high temperature elements of the left engine.

The aircraft was destroyed and all six occupants were killed.
Probable cause:
It was reported that the left elevator failed on final approach due to the failure of several bolts located on the inner part of the elevator. This was the result of a faulty maintenance on the part of the technicians of the company. Wrong reaction on part of the crew was considered as a contributory factor.
