The medical evacuation (MEDEVAC) flight departed Wollaston Lake, Saskatchewan, at 23:25 CST (central standard time), en route to La Ronge. After take-off, the aircraft turned about 70 degrees to the left, descended, and struck the frozen surface of Wollaston Lake. The pilot and the patient suffered serious injuries; the other two occupants suffered minor injuries. The aircraft was destroyed. Both pilot and patient medevaced to Saskatoon.
The accident occurred during the hours of darkness at latitude 58"6.98'N, longitude 103"10.79'W, at an elevation of 1,300 feet above sea level (asl). The temperature was about -25C
The Transportation Safety Board determined that, after take-off, the left propeller was likely on its start locks, which, as the airspeed increased, allowed the propeller to over speed. The pilot was unable to resolve the situation in time to prevent the aircraft from striking the surface of Wollaston Lake. Contributing to the severity of the patient's injuries were the inadequate restraint provided by the stretcher and its restraining strap, the lack of standards regarding stretchers used in aircraft, and the lack of standards as to the operation of MEDEVAC flights.
