Report Findings accuracy
I cannot speak to the findings in this cae and I have not made a study of the report but I do have some experience of Russian aircraft accident reports having been in a crash on the Kola
Our aircraft was out of control from about 100 feet on the approach to a wild landing sight on a river bank. It seemed to me to be a classic vortex ring given the circumstances of the approach, slight tailwind, high power hover, slow rate of descent, slow forward movement
We hit the ground very hard, thank you Russians for a helo built like a boiler house, cartwheeled, rolled, a minor fire developed and the tail cone lay across the door. All the wheels remained intact but the aircraft nose was destroyed, we had struck nose first.
The report said the pilot allowed the tail to touch the ground during the landing
The Russian investigator told me vortex ring was not a Russian problem.
In this sort of environment reports become suspect
