The helicopter impacted the waters of Kuril Lake, Kamchatka Peninsula during a tourist flight. Eight occupants were rescued.
The helicopter sank in 110 m deep water in the volcanic lake 500 m from shore.
13-AUG-2021 - Vityaz-Aero banned from carriage of passengers. It is still permitted to conduct cargo transport and other aerial work, including medical services.
Conclusion:
The cause of the accident with the Mi-8T helicopter RA-24744 was the failure of the pilot to make a timely decision to fly to an alternate airfield in meteorological conditions not corresponding to VFR and the level of crew training, which led to uncontrolled descent and collision of the aircraft with the water surface.
The most likely contributing factors were:
- Lack of sufficient training of the crew to perform instrument maneuvers in order to get out of conditions inconsistent with the VFR;
- the crew's failure to comply with the provisions of the flight manual and the Mi-8 helicopter crew operating procedures when the "Dangerous Altitude" audible alarm was triggered;
- psychological peculiarities of the pilot's personality associated with a decrease, probably of age, in logical and analytical thinking to a level below average, as well as with an excessive propensity to risk, with disregard and underestimation of danger, which, among other things, did not allow him to learn the required lessons after a similar aviation accident in the past;
- Insufficient preventive work in the airline based on the results of the investigation of previous aviation events.
