Circumstances:

On a flight from Ulan-Ude to Nizhneangarsk, while descending to an altitude of 3,050 metres 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. After touchdown, the crew started the braking procedure when the airplane deviated to the right then veered off runway. It rolled in a grassy area, cwent through the perimeter fence and eventually impacted the building of a sewage treatment plant located 380 metres to the right of the runway centerline. The captain and the flight engineer were killed and the copilot was seriously injured. 10 other occupants were injured. The aircraft was destroyed by a post crash fire.

Circumstances:

After being cleared, the crew initiated the descent from 3,000 meters to 2,700 meters then continued when, at an altitude of 2,226 meters, the twin engine aircraft struck the slope of a mountain located 74 km from Bagdarin Airport. The aircraft disintegrated on impact and all 17 occupants were killed. At the time of the accident, the visibility was poor due to low clouds and snow falls.

Probable cause:

It was determined that the crew made a wrong flight time calculation and misevaluated the climbing time, causing a discrepancy of 11 minutes. Due to radio communications problems and also unstable radiogoniometric systems, ATC was unable to establish the exact position of the aircraft. The crew started the approach prematurely, causing the aircraft to descent below the minimum safe altitude. Due to lack of visibility, the crew was unable to see and avoid the mountain.

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:

After departure from an airfield located in a mountainous area, the single engine airplane did not reach the required speed for climb and at a distance of about 1,050 meters from the aerodrome, at a height of 15-20 meters, it struck tree tops. The captain shut down the engine and completed an emergency landing in a wooded area. While the aircraft was damaged beyond repair, all 12 occupants escaped uninjured.

Probable cause:

Failure of the crew to release the flaps prior to takeoff that was completed at a too low speed. A lack of crew training in such operations was considered as a contributing factor.
