details

The investigation established that the crew in the calculation of the flight plan allowed the error to 11 minutes to decrease the period of flight, due to neglect of the time climbing 2400 meters on the airfield circuit IUJ resulting take-off, as well as wind speed and direction on the route.

After the crew reported the move to communicate with the dispatcher Bagdarin for 7 minute flight took place without communication because of the limited range of terrestrial radio stations.

In view of the shortcomings in the chart calculation, not complex when piloting a small range of the radio equipment airfield landing and takeoff of aircraft located in 24 km to the right of the track. Error crew calculated the distance to the destination aerodrome was 50 km. As a result, when establishing a connection manager airfield Bagdarin crew handed instead 05: 21 MSK ETA 05: 10 MSK, and this indicates ignorance of the location.

When requesting authorization for a visual approach and reduced crew manager misinformed about flight conditions and location of the aircraft, reported that visually follows.

Not being able to identify where the aircraft is, the controller in poor and unstable radio direction finder testimony given permission to take the train crew 3000 m, then and then visually 2700 1000 m QFE. However, the deviation to the right of the aircraft from the given path is not allowed for visual flight, as a cold front approaching the west to the line of the track.

The plane was in the clouds at times, icing conditions and precipitation. Crew out of sight terrestrial landmarks recklessly started to decrease for employment 1000 m QFE.

1140 plane at ground level (2226 m above sea level) crashed into a mountainside and ended up in disaster.
