It drives me nuts how often reports cite VRS as the cause when clearly there other more likely potential causes
The ATSB seem to have a penchant for VRS.
Talking to the company pilot with whom the test flights were done in the following accident at no time were they able to enter VRS, and the ATSB chap occupying the other seat agreed. Once he got back to the office the story changed, so the report chapter on the testing would seem to be bollox. The conclusion reached in the testing was that the crew developed a high rate of descent in rearward flight. Remember getting the turbine endorsement in a UH-1B, one flight was a instructor demonstration of VRS at 14,000, wearing a parachute which was required for flight above 5,000, at our light weight we were unable to achieve the aim
