Conclusion
The aviation accident involving the Mi-8AMT helicopter RA-22833 occurred due to errors made by the captain in piloting, specifically during an aggressive speed reduction maneuver. These errors led to an increase in the vertical descent rate and the helicopter transitioning into a "vortex ring" state. The insufficient altitude did not allow the captain to recover from the descent, resulting in a collision with trees and subsequently with the ground.
It is most likely that the aviation incident was exacerbated by local deteriorating visibility conditions, preventing the captain from visually detecting the low-contrast landing area in a timely manner and diverting their attention from piloting the aircraft to search for it.
