Circumstances:
On a flight from Ulan-Ude to Nizhneangarsk, while descending to an altitude of 3,050 meters about 30 km from the destination airport, the crew contacted ATC and reported the failure of the left engine. The approach was continued to runway 22 and after touchdown, the crew started the braking procedure when the airplane veered off runway to the right. It rolled in a grassy area and eventually impacted the building of a sewage treatment plant located 380 meters to the right of the runway. The captain and the flight engineer were killed and the copilot was seriously injured. 22 other occupants were injured. The aircraft was destroyed by a post crash fire.

Circumstances:
The airplane departed Severomuysk Airport at 1441LT on a schedule service to Ulan-Ude with an intermediate stop in Nizhneangarsk, carrying 44 passengers and a crew of four. Bound to the west, while cruising to an altitude of 3,600 meters, the crew was informed about poor weather conditions at destination. As the Nizhneangarsk Airport was closed to traffic, the crew was instructed to divert to Ust-Barguzin Airport located on the east shore of Lake Baykal, in the Svyatoi Nos peninsula. While descending to Ust-Barguzin Airport at an altitude of 1,300 meters, the airplane struck the slope of a mountain and crashed 30 km northwest of Ust-Barguzin. The airplane was destroyed upon impact and all 48 occupants were killed.
Probable cause:
It was determined that the crew failed to follow the prescribed procedures and initiated the descent prematurely under VFR mode in IMC conditions. Due to unfavorable wind component (200° at 25 km/h iso 250° at 50 km/h as initially forecasted), the airplane was not on the calculated route and ATC was unaware of the exact position of the airplane due to lack of contact from the crew and due to discrepancies in the radiogoniometer settings. This situation resulted in a controlled flight into terrain.

Circumstances:
The single engine airplane departed Irkutsk Airport at 1530LT on a flight to Nizhneangarsk, Buryatia, with an intermediate stop in Kachug, carrying one passenger, two pilots and a load of 800 kilos of various goods on behalf of a geological expedition. Following a fuel stop in Kachug, the crew departed Kachug Airport at 1710LT in marginal weather conditions. At 1727LT, the crew requested and was cleared to descend from 2,700 meters to 2,300 meters for unknown reasons. Twelve minutes later, while cruising at an altitude of 2,300 meters, the crew informed ATC about his position in the region of the Touloun Lake and gave his ETA for the next point over Cape Sheremshan at 1815LT. As the crew failed to contact ATC and the aircraft did not arrive in Nizhneangarsk, SAR operations were initiated but eventually abandoned 17 days later as no trace of the aircraft nor the three occupants was found. It is believed that the airplane crashed in a mountainous region located northwest of Baïkal Lake, near the border between Irkutsk oblast and the Republic of Buryatia.
Probable cause:
Due to lack of evidences as the wreckage was not found, the exact cause of the accident could not be determined. However, the following three hypothesis were not ruled out:
- Loss of control due to severe icing,
- Engine failure,
- Controlled flight into terrain while cruising in clouds.

The aircraft was destroyed by a post crash fire and while two passengers were seriously injured, all five other occupants were killed.

The accident was the consequence of the crew’s violation of the rules for flight operations in accordance with the published procedures established by ULP. Weather and ATC were not considered as contributing factors.

Circumstances:
The crew departed Nizhneangarsk Airport at 0843LT on a cargo flight to Dovyren and Irkana, carrying a load of six diesel drums. Twelve minutes later, the crew reported he was climbing to an altitude of 1,200 meters in good weather conditions. About ten minutes later, the single engine airplane crashed in a mountainous area located 7-10 km from Dovyren. As the aircraft failed to arrive at Dovyren, SAR oeprations were conducted and the wreckage was found a day later. Both crew members were killed.
Probable cause:
It was determined that one of the propeller blades failed in flight and struck and broke the windshield. In low visibility caused by snow falls, the crew was unable to attempt an emergency landing as he was flying over a mountainous area. The failure of the propeller blade was caused by a faulty manufacture.
