The Transportation Safety Board of Canada has released the results of an investigation into a fatal helicopter crash last summer in the Carcross area of Yukon territory.
Pilot Paul Rosset of Yellowknife was killed in the crash in July of last year. Two Yukon government surveyors were also injured.
The report found that the pilot had not done a reconnaissance pass to determine conditions in the landing area.
As a result, he was unaware of intense downflowing air that day.
It says the pilot was also not wearing his helmet.
The company, Horizon Helicopters, has since implemented a safety policy requiring all pilots to wear helmets. The company had no comment this morning.
