Probable cause

The pilot exceeded the critical angle of attack during takeoff, which resulted in an aerodynamic stall and a collision with terrain.

NTSB narrative

The pilot reported that after taking off from a frozen gravel bar by a river in remote wilderness, the airplane stalled. The left main landing gear struck the edge of the cut bank and the left wing impacted the ground. The fuselage then impacted the top of the bank and spun counterclockwise. The pilot stated that the left wing was separated from the fuselage and the fuselage had sustained substantial damage. The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
