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.

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.

Circumstances:
The aircraft was completing a cargo flight from Tyumen to Ufa, carrying seven passengers, six crew members, a car and a container. On approach to Ufa Airport, the crew encountered poor weather conditions (night, sleet and low clouds) and limited visibility. On short final, the aircraft struck trees 1,098 metres short of runway, lost height and crashed in a wooded area, some 179 metres to the right of the extended centerline, bursting into flames. Eight occupants were killed and five others were injured.
Probable cause:
It was determined that the crew continued the approach in a visibility of 1,200 metres that was below minimums at the time of the accident, until the aircraft collided with obstacles and impacted terrain.

Circumstances:
The aircraft departed Sibay on a special flight to Magnitogorsk, carrying five members of the Civil Defense and two pilots. The purpose of the mission was to fly over the Ural River to study and predict flood activity. After takeoff, while in initial climb, the crew initiated a left turn when the aircraft entered an uncontrolled descent and struck the ground in a nose down angle of 40° about 1,280 metres from the runway end. A pilot and two passengers were killed while four other occupants were injured. The aircraft was destroyed.
Probable cause:
It was determined that the crew failed to prepare the flight according to published procedures and failed to follow the pre-takeoff checklist. It was found that the tail assembly was locked with a clamp that was installed by a ground mechanic and not removed prior to departure.

Circumstances:
The crew was engaged in a local test flight before completing a crop spraying mission. Following a running distance of 250-280 meters on takeoff, the pilot-in-command started the rotation. Unable to maintain a positive rate of climb, the airplane struck tree tops, stalled and crashed upside down 78 meters further in a field, about 1,037 meters after the start of the take off run. The aircraft was destroyed and all three occupants were killed.
Probable cause:
It was determined that the total weight of the aircraft at takeoff was 779 kilos above the MTOW. Following a too short takeoff roll, the pilot-in-command rotated prematurely. Due to an insufficient speed, the airplane was unable to maintain a positive rate of climb and a correct climb path.

A fuel tank was punctured and the aircraft caught fire. Out of control, it veered off runway to the right and came to rest in flames. All 89 occupants survived, 10 of them, including two crew members, were injured. The aircraft was destroyed by fire.
Probable cause:
Poor approach planning on part of the flying crew who failed to follow the approach checklist and completed the landing procedure with the wheel brakes locked.

Circumstances:
The crew departed Beloretsk at 0709LT on a prospection mission in the region of Inzer on behalf of a logging program for the Ural Geological Administration, carrying three passengers and three crew members. At 0730LT, the crew informed ATC about his position and that he would start soon the aerial work. While cruising in clouds (400 to 600 meters above the ground), the airplane crashed on the east slope of Mt Yamantau (976 meters high) located 35 km east of Inzer. As the contact was interrupted with the crew and that the airplane failed to return to its base, SAR operations were initiated and the burned wreckage was found two days later about 70 meters below the summit of the mountain. All six occupants have been killed.
Probable cause:
It was determined that the accident was the consequence of a loss of control in altitude after the airplane encountered orographic currents specific to the terrain of Mt Yamantau. Despite a reaction from the crew who increased the engine power, he was unable to maintain a suitable control of the airplane.
