A twin-engine aircraft crashed on ice near Wollaston Lake, Saskatchewan, after losing control in known icing conditions. All four occupants, including two RCMP pilots, suffered fatal injuries.

Accident

On the second leg of a flight from La Ronge, Saskatchewan, a twin-engine aircraft departed the Welcome Bay ice strip at Wollaston Lake, Saskatchewan. On board were two Royal Canadian Mounted Police (RCMP) pilots, another RCMP member, and an inspector from the Saskatchewan Department of Public Works. Witnesses reported that the aircraft took off normally, leveled momentarily, then climbed steeply into cloud. Moments later, they heard the engine noise increase abruptly, then decrease rapidly, followed by a sound similar to a backfire. When the aircraft reappeared, it was in a steep, nose-down, right-wing-low attitude. It crashed on the ice, one mile north of Welcome Bay; all four occupants sustained fatal injuries.
