Circumstances:
The single engine aircraft was performing an on-demand flight from Petropavlovka to Toora-Khem with seven fishermen and a pilot who want to go to a remote fish camp located in the natural reserve of Azas. While flying at low altitude, the aircraft went out of control and crashed on the shore of the Choigan-Khole Lake, near the Sorug River. While all seven passengers escaped with minor injuries, the pilot was killed. It appears that the aircraft was not registered and did not have any certificate of airworthiness. Therefore, the flight was considered as illegal and no flight plan was filed.

Circumstances:
The aircraft was chartered by a local hospital in Kyzyl to transfer to Toora-Khem 12 passengers (two patients, four accompanists and a medical team of six crew) and two pilots. After takeoff, the crew was cleared to climb to an altitude of 2,300 meters bound to the north. At 1245LT, the crew reported his position over the mountains and informed ATC about the next point of report. Shortly later, the crew decided to modify his route and to follow a shorter route when weather conditions worsened with poor visibility due to snow falls. While cruising at an altitude of 2,330 meters, the single engine airplane struck a rocky wall of 2,466 meters high. As the airplane failed to arrive at destination, SAR operations were initiated but the wreckage was found five days later, on November 6, about 76 km north of Kyzyl. The aircraft disintegrated on impact and all 14 occupants were killed.
Probable cause:
The decision of the crew to modify his route without permission and to continue in IMC conditions at an insufficient altitude, resulting in a control flight into terrain.

Circumstances:
On a flight Kyzyl to Khovu-Aksy, the crew encountered below-minima weather conditions with low clouds over the mountains. The captain took the decision to continue into the clouds when the airplane struck at a speed of 200 km/h and a height of 1,940 metres the wooded slope of a mountain (2,591 metres) located 13 km south of Khovu-Aksy. The wreckage was found a day later and all 14 occupants have been killed.
Probable cause:
The crew took the decision to continue into clouds without any visual contact with the ground or obstacles. Controlled flight into terrain. Weather conditions were considered as worse than predicted.

Circumstances:
On the leg from Teeli to Mugur-Aksy of a flight from Kyzyl to Mugur-Aksy, the crew entered clouds while approaching Mugur-Aksy Airport and deviated from the approach path in the direction to the mountains. The decision to go around was correct but taken too late as the aircraft crashed at a height of 300 metres above the airport's elevation into the snow-covered slope of a mountain (2,123 metres) located some 7 km west of the airport. The aircraft caught fire and burnt out. While six passengers were killed, all eight other occupants, including both pilots, were seriously injured.
Probable cause:
Wrong approach configuration on part of the flying crew who decided too late to attempt a go-around while descending in poor visibility. As the crew was non compliant with the published procedures, this caused the airplane to follow a wrong approach path. Lack of visibility caused by poor weather conditions was considered as a contributing factor.

Aircraft flight hours:

Circumstances:
The crew was engaged in a geophysical survey flight in the Republic of Tuva on behalf of the Russian Ministry of Geology (Ministerstvo Geologii – MinGeo). While cruising in marginal weather conditions, the single engine aircraft hit with its right main gear the top of Mt Hor-Taiga (2,618 meters high) and crashed into a ravine. The flight engineer was killed while four other occupants were injured. Two of them walked away to find help and came back a day later to evacuate the other survivors. The navigator died from his injuries 16 hours later. The aircraft, brand new, was destroyed.
Probable cause:
It was determined that the accident was caused by a poor flight preparation on part of the crew and the combination of the following factors:
- lack of crew training that failed to guarantee a sufficient flight safety level,
- lack of pilot experience in conducting geophysical survey flights,
- incomplet meteorological informations for mountainous terrain,
- absence of a flight manual and procedures regarding aerial photography missions,
- overconfidence on part of the navigator who had more than five years experience in this type of mission,
- deterioration of weather conditions during flight.
