On May 25, 2012, the de Havilland Beaver float plane operated by Cochrane Air service stalled and crashed during a second attempt to land in gusty conditions.
All three people aboard survived the initial impact, but only one person was able to successfully escape; the other two drowned, said the TSB report.
On the heels of a TSB investigation, it is making two recommendations "aimed at improving the odds that anyone who survives a float-plane crash will get out alive."
“In an emergency, you only have seconds to orient yourself and escape, and the right training can make the difference between life and death. Pilots with underwater egress training stand a better chance of helping themselves and their passengers survive,” said chair Wendy Tadros.
“Another thing that will help immeasurably is shoulder harnesses. Too many passengers survive a float-plane crash only to drown because they have suffered some kind of head trauma and can’t get out of the aircraft.”
Recommendations aim to prevent deaths
These new recommendations are in addition to two outstanding ones aimed at making floatplanes safer, said Tadros in a statement released on Wednesday.
After an investigation into the fatal 2009 float-plane crash that killed six passengers in Lyall Harbour, B.C., the TSB called for pop-out windows and doors to better facilitate egress and for personal flotation devices for all passengers.
Transport Canada has committed to making flotation devices mandatory, but has not committed to requiring floatplane doors and windows to come off easily after a crash.
“When a float-plane crashes on water, approximately 70 per cent of crash victims die from drowning. All four board recommendations are aimed at changing that reality,” said Tadros.
“Transport Canada needs to treat all four recommendations with the seriousness they deserve, and take every measure to prevent more from dying in otherwise survivable accidents.”
