Description
The ski-equipped Otter was parked outside overnight at Schaft Creek Airstrip, BC, Canada. Prior to departure a layer of ice on the upper surfaces of the wings had not been completely removed. The pilot took off at near-maximum permissible loading and climbed away slowly in a right turn after a long ground run. There was insufficient altitude to cross a mountain pass ahead and as the turn rate was increased to avoid the mountain, the aircraft stalled and came down on the snow-covered western slope of the mountain pass.
