Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

The plt's failure to properly compensate for the wind during takeoff on unsuitable terrain. Contributing to the accident were the terrain conditions and gusting winds.

Analysis

The plt attempted a takeoff from a rough and uneven frozen river in the ski equipped acft. The takeoff was made into winds of 20 KTS gusting to 35 KTS. As the acft reached a speed of aprx 35 KTS, a gust of wind, combined with the acft bouncing on the rough terrain, tipped the acft, causing the wing to drag and the acft to cartwheel.
