Circumstances:
Seven passengers embarked at Przhevalsk Airport and after takeoff, the crew climbed to the altitude of 2,700 meters in a visibility of 5 km. After passing the Santash Pass, weather conditions worsened and the visibility dropped below minimums. The captain decided to reduce his altitude and to continue below the clouds. In a visibility reduced to one km due to snow falls and at high speed, the single engine airplane struck a snow covered hill and disintegrated on impact. All nine occupants were killed.
Probable cause:
The decision of the captain to reduce his altitude without ATC clearance and to continue the flight in a visibility that was below minimums until impact with the ground. A poor flight preparation on part of the crew was considered as a contributing factor.

Circumstances:
The single engine aircraft departed Semipalatinsk Airport at 0917LT on a flight to Abay, carrying 10 passengers and two pilots. About fifteen minutes after takeoff, the crew encountered poor weather conditions with a sky broken from 600 to 1,000 meters, snow falls, wind up to 45 km/h and a visibility between 4 and 6 km. In such conditions, ATC instructed the crew to return to Semipalatinsk and the crew confirmed this instruction when the contact was lost at 0936LT. SAR operations were conducted and the burned wreckage was found in a snow covered field located 35 km south of Semipalatinsk. The aircraft was totally destroyed and all 12 occupants were killed.
Probable cause:
Investigations determined that the immediate cause of the accident was a loss of speed resulting in a stall of the aircraft due to a loss of longitudinal controllability when the aircraft's center of gravity moved beyond the range of 40-42% of the envelope. The movement of the CofG occurred when several passengers moved from the rear of the cabin (toilet). Poor flight preparation on part of the flying crew who failed to check the weather conditions properly and the lack of visibility were considered as contributing factors.

At the end of the mission, the crew was returning to the east and while flying face to the sun at a height of 1,046 meters, the single engine aircraft struck tree tops and crashed in flames in a dense wooded area located about 145 km west of Aldan. The captain and the flight engineer were killed instantly. The flight operator and the navigator were injured and walked away to find help. After four km walk, the navigator died from his injuries and his body was found thirteen days later on July 18. The flight operator eventually find help and was evacuated to a local hospital. At the time of the accident, the visibility was reduced to one km due to clouds.
Probable cause:
It was determined that the crew failed to take into consideration the high OAT ( 23°) and its effect on the rate of climb and the airplane's performances. Also, the following factors were considered as contributing:
- The crew failed to make any reconnaissance flight prior to the mission,
- Flying against the sun,
- Poor flight preparation.

Probable cause:
It was determined that the crew failed to secure the load properly prior to takeoff. At rotation, the freight moved to the rear of the cabin, causing the CofG to be out of the enveloppe and the aircraft to be out of control.

Circumstances:
At Pelengachi Airport, the captain was told that weather conditions were poor all along the route and that operations were suspended. Despite the situation, he took the decision to leave Pelengachi bound to Kazhim with three other crew members. After takeoff, the single engine airplane climbed to an altitude of 200-300 meters before it disappeared in the clouds. Twenty-three minutes later, while cruising in low visibility, the airplane struck the slope of a mountain and disintegrated on impact. All four crew members were killed.
Probable cause:
Wrong decision on part of the captain to perform the flight despite poor weather conditions. Lack of operations supervision on part of the authority was also reported. It is believed the captain was tired at the time of the accident due to insufficient rest time. Also, he was apparently intoxicated, which contributed to the accident.
