Circumstances:
The aircraft departed Sibay Airport with 13 passengers and a crew of three including one inspector. Despite marginal weather conditions, the crew initiated the flight under VFR mode. After takeoff, the crew failed to follow the departure route and deviated from the published one. About half an hour into the flight, weather conditions deteriorated with low clouds. After the aircraft entered clouds, the captain decided to return to Sibay but this decision was taken too late. At this time, the aircraft was off course by 45 km to the northeast of the initial route. While making a turn to the left, still in the clouds, the crew failed to realize his altitude was too low when, at an altitude of 980 metres, the aircraft collided with trees and crashed on the slope of Mt Masim (1,040 metres high). All 16 occupants were rescued, among them three passengers were injured.
Probable cause:
The following findings were identified:
- Poor flight planning and preparation,
- The crew decided to continue the flight under VFR mode in IMC conditions,
- The crew deviated from the initial course and then continued over mountainous terrain below the minimum prescribed altitude,
- The flight inspector failed to verify that the crew prepared the flight according to published procedures,
- Lack of ATC assistance,
- Lack of visibility due to low clouds.

The single engine airplane departed Togliatti on a local skydiving mission, carrying 10 skydivers and two pilots. While flying over the region of Lunacharski, all skydivers jumped out but two of them fell in the Volga River and drowned. The crew elected to take part to the SAR operations and wanted to show the location to the rescuers but descended too low over water. The aircraft stuck the water surface and crashed. Both pilots were injured and the aircraft was destroyed.
Probable cause:
The crew misjudged the distance with the water surface and descended too low.

Few minutes after takeoff from Yakutsk-Magan Airport, while cruising at an altitude of 1,150 metres at a speed of 180 km/h, the engine started to vibrate and lost power, Also, the oil pressure dropped and the speed decreased. The captain attempted an emergency landing in a swampy area when the aircraft rolled for about 32 metres and nosed over. A passenger was killed and all other occupants were injured, four seriously.
Probable cause:
Engine failure following the failure of the first cylinder and piston due to fatigue.

Probable cause:
The aircraft stalled during initial climb because snow and ice/frost remained on the wings, tail and fuselage. The following factors were identified:
- The crew failed to inspect the aircraft prior to takeoff,
- The crew failed to prepare the flight according to published procedures,
- The crew failed to proceed to an appropriate pre-takeoff deicing/cleaning.

Circumstances:
The crew was engaged in a spraying mission in Novomusino. After departure, at a height of 50 metres, the crew raised the flaps and continued at a speed of 140 km/h. Approaching the area to be treated, the crew realized his position was incorrect and elected to gain speed and height when the aircraft stalled and crashed. Both pilots escaped uninjured and the aircraft was damaged beyond repair.
Probable cause:
The accident was the consequence of mistakes made by the crew in choosing the route and the engine operating mode which led to the need to increase the vertical speed with a lack of thrust below the safe altitude. The aircraft adopted a high angle of attack, lost speed and struck a hillside.
