There was no mechanical failure involved in an April 16 helicopter crash near Rancheria, the Transportation Safety Board of Canada has found.

While there was substantial damage to the Bell 206 Long Ranger, neither the pilot nor the two passengers were injured, says the incident report issued recently by board investigator Mike Tomm.

Tomm said in an interview this week from Edmonton the helicopter was airlifted off the mountain two or three days later. It was then trucked to Kamloops, B.C. for an inspection but no mechanical issues were found.

The crew from Trinity Helicopters out of Yellowknife was flying to Whitehorse to do some work and had stopped at Watson Lake, according to Tomm's report.

"After departure from Watson Lake, the aircraft was crossing a ridge at approximately 5,000 feet above sea level when a decision was made to land on top of a mountain,” reads the report. "After determining the wind direction, the pilot approached the landing area into the wind. On short final, the helicopter entered an unanticipated yaw to the right.

"The aircraft landed hard and rolled onto its left side.”

Tomm said wind may have been a contributing factor.

Veteran pilot Rob Carroll, who is also the president of the five-month-old helicopter company, said this morning from his Yellowknife office he is unable to say much as the matter is still under investigation.

"We are not sure what the issue was,” he said. "We do know there were no injuries, and that's all we are saying right now.”

Carroll did confirm that after the crash, he and the two others walked off the mountain and down to the Rancheria highway lodge.
