The float-equipped de Havilland Beaver DHC-2 aircraft, operated by Lawrence Bay Airways, left Buss Lakes on June 30, 2011, and went into the water about 3.7 kilometres away.
"The aircraft entered an aerodynamic stall," Peter Hildebrand, TSB regional operations manager, said in a news release. "The stall occurred at an altitude from which recovery was not possible."
Aerodynamic stall occurs when there is not enough air flowing over the wings to keep the craft aloft. If there's enough time and altitude, a pilot can recover, but in this case that didn't happen.
The five victims included:
- Danny Mantyka, 21, of Prince Albert, Sask.
- Max Clunie, 15, also from Prince Albert.
- Wade Cooper, 44, from the Senlac area of Saskatchewan.
- Cam Cooper, 40, his brother, also from the Senlac area.
- Andre Gagnon, 32, from Sherbrooke, Que.
The group had chartered the plane to take them to a private cabin on Buss Lakes for a four-day fishing trip.
