In deteriorating visibility the helicopter impacted the ground 700m from the helipad coming to rest on its left side after entering VRS at low speed on approach. One occupant, the aircraft commander, died and the other five occupants were injured (one seriously).
Conclusion:
The helicopter collision with the ground occurred due to the crew's failure to control the vertical rate of descent due to distraction of attention to visual search for the landing site in the course of landing approach at night in instrumental weather conditions, which resulted in vigorous descent of the aircraft and, most probably, in entering the vortex ring mode, from which exit was impossible due to low flight altitude.
The accident resulted from the crew's failure to make a timely decision to leave for an alternate airfield when weather conditions at the landing site deteriorated to below the values established for flight at VFR.
Most likely, the following factors contributed to the accident:
- unsatisfactory crew cooperation in controlling the flight regime;
- Landing approach at altitudes and speeds lower than those specified in the helicopter's flight manual;
- Shortcomings in the selection of crew members in terms of their professional skills for working away from base, which prevented them from ensuring effective flight organisation and safety;
- Lack of an effective system for monitoring the work of crews at the operating site;
- Shortcomings of the UTair - Helicopter Services JSC flight safety management system, which did not allow identifying existing hazards and reducing the level of risk when performing aviation operations in the difficult conditions of the Polar region.
