Aircraft Accident/Incident Report

Mcgrath, Alaska 99627
Thursday, March 12, 1998 14:30 AST

NTSB Narrative Summary Released at Completion of Accident

The commercial pilot landed his wheel/ski equipped airplane on a frozen river. The pilot stated that after landing, he added power in an attempt to lift the tail, and turn the airplane in the opposite direction. The airplane's skis became stuck in grooves on the snow, and directional control was lost. The airplane's left wing struck a tree on the river bank and substantial damage was sustained to the leading edge. Wind conditions at the time of the accident were reported by the pilot to be calm.

NTSB Probable Cause Narrative

The pilot's failure to maintain directional control after landing. Factors associated with the accident are the presence of snow covered terrain, a tree, and the pilot's selection of an unsuitable landing area.
