Narrative:
The Bell 206B JetRanger II crashed in a lake. The pilot was killed.


Most likely, the cause of the Bell 206В RA-01625 helicopter crash was a pilot error when taking off from a high-altitude platform, which manifested itself in an intensive turn to the right while hovering, which led to falling under the influence of a tailwind, the development of a "spontaneous" right rotation mode and a collision with a water surface.

The most likely contributing factors were:
- the PIC's lack of training for flying on the Bell 206В aircraft;
- disregard of the PIC of the surface wind regime during take-off;
- failure to take timely measures (until the moment it became impossible) to stop the rotation of the helicopter.
