Crash of a De Havilland DHC-2 Beaver near Challis: 4 killed

The pilot took off from the Simplot Ranch Airstrip which was located beside the middle fork of the Salmon River, approximately 27 miles northwest of Challis, ID. He departed downriver toward the northeast, but the destination was a usfs strip about 7 miles upriver to the southwest. A course reversal normally would have been made about 6 miles downriver. However, a turn-around was attempted over a relatively shallow (bench) area on the west side of the river, about 1-1/4 mi from the departure strip; where, according to the operator, it could have been made under ideal conditions. The aircraft crashed in the bench area while on a westerly heading. It came to rest in an upright attitude with little evidence of forward velocity, but with severe vertical collapse. No evidence of a pre-impact mechanical malfunction or failure was found. All four occupants were killed.
