Narrative:The helicopter crashed on the frozen surface of the Angara River. Both occupants died.
Conclusion:
Most likely, the accident with the Eurocopter AS350B3 RA-07277 was due to the loss of control of the helicopter while flying in conditions of limited visibility, out of sight of the horizon and landmarks. It was not possible to unambiguously determine the cause of the loss of control.
Possible reasons could be: loss of spatial orientation by the pilot in flight conditions for which he was not prepared, or partial or complete loss of performance in flight caused by cardiovascular pathologies, or a combination of these reasons.
The contributing factors, most likely, were:
- unfounded decision by the pilot to continue the flight in conditions for which he was not prepared;
- significant psychoemotional load during flight in conditions of limited visibility;
No signs of failure of the helicopter onboard systems and assemblies were identified until the accident.
