Circumstances:
Aircraft left Lensk at 0813LT on a flight to Bratsk. While cruising at 4,200 metres, the engine failed. Crew elected to divert to Kirensk but eventually made an emergency landing in a wooded area. All nine occupants were injured as the aircraft was damaged beyond repair.
Probable cause:
Engine failure due to the damage of the bearings of the planetary gear from the first stage, leading to vibration and destruction of the turbine. It is possible the damage to the bearings was caused by the presence of aluminium or silicon oxide. However, it was not possible to determinate the source of this contamination.

Circumstances:
The airplane departed Moscow-Vnukovo Airport on a schedule service to Bratsk with an intermediate stop in Omsk. On approach to Bratsk Airport, the crew encountered limited visibility due to heavy rain falls. One second after touchdown, the reverses were activated on all three engines and the airplane rolled for about 800 meters when it started to veer to the left. The pilot-in-command attempted to counteract the deviated but the airplane rolled another 526 meters when it veered off runway. It rolled few dozen meters on soft ground then came to rest, broken in two. All occupants escaped uninjured.
Probable cause:
The cause of the accident was the uncontrollability of the aircraft on a wet runway due to the complete loss of rudder efficiency at the maximum reverse engine thrust due to the design characteristics of the aircraft.

Circumstances:
The crew was completing a flight from Chita to Bratsk with an intermediate stop in Irkutsk. While descending to Bratsk Airport, the crew was instructed to divert to Zheleznogorsk-Ilimski Airport because weather conditions at Bratsk Airport were below minimums. Few minutes later, for unknown reasons, the crew decided to return to Bratsk when the airplane ran out of fuel. The left engine flamed out so the crew attempted an emergency landing on the iced Tareva Bay located on the north shore of the Bratsk Reservoir, about 40 km southwest of Vidim. All six crew members escaped with minor injuries while the aircraft was damaged beyond repair.
Probable cause:
Engine failure caused by a fuel exhaustion.

En route from Irkutsk to Bratsk, weather conditions worsened with thunderstorms. The crew deviated from the prescribed route when few minutes later, the fuel alarm sounded. The crew attempted an emergency landing when the airplane crash landed in a wooded area. There were no casualties but the aircraft was damaged beyond repair.
Probable cause:
Low fuel conditions forced the crew to attempt an emergency landing. The weather forecast bulletin transmitted to the crew did not reflect the truth and did not mention any thunderstorm activity en route.

While cruising by night, the pilot informed ATC that he lost the artificial horizon. Shortly later, control was lost and the airplane entered a dive. It partially disintegrated during the descent and eventually crashed in a pasture. The aircraft was totally destroyed and all seven occupants were killed.
Probable cause:
Failure of the artificial horizon for unknown reasons. The airplane later disintegrated in the air due to aerodynamic forces that exceeded its design and certification.

Circumstances:
The three engine aircraft departed Irkutsk-Magan Airport at 2229LT bound to the north, cruising at an altitude of 6,000 meters. Weather conditions en route were good. While descending to Bratsk Airport, the crew was informed about the last weather bulletin with no precipitations and a visibility of 50 km. However, during the night approach, weather conditions deteriorated with heavy mixed rain/snow showers and a visibility limited to one km. On short final, the airplane lost height then struck trees and crashed in flames 225 meters further, about 1,250 meters short of runway threshold. The airplane was destroyed by impact forces and a post crash fire and all 18 occupants were killed.
Probable cause:
It was determined that ATC in Bratsk transmitted to the crew a wrong weather bulletin that was referring to weather conditions at 2315LT. Unfortunately, ATC attempted without success to obtain an updated weather briefing and transmitted inaccurate information to the crew. On final, heavy snow/rain showers associated with downdraft and unfavorable winds caused the aircraft to lose height and to crash. The assumption that the crew inadvertently selected the reverse thrust during final approach was not ruled out.
