Probable Cause:The fact-finding of the commission for investigation, concluded that occurred as a result of a.o, a combination of the following unfavorable factors:
- incorrect calculation by the crew of the necessary quantity of fuel for the execution of flight to Tura taking into account Vanavara being the alternate airport;
- sudden weather deterioration on Tura Airport, about which the crew was not informed in time;
- failure by Tura airport personnel to conduct observations at a time when the weather was worsening, and failure of the flight control officer to keep proper control of the work of the subordinates;
- the deviation, allowed by crew during the first straight-in approach, which was caused, probably, by short-term de-energizing of the Outer Marker beacon and by incorrect determination by the crew of removal to VPP under these conditions;
- failure of the crew to monitor the approach pattern parameters during the second and third approaches into Tura under the weather conditions below the established minimum;
- wrong decision by the crew regarding the shortage of fuel by choosing the alternate Of Vanavara instead of Baykit Airport, located on 110 km closer;
- the error of the crew in the selection flight altitude and the premature descent into Vanavara.
