Probable cause

The pilot’s failure to maintain clearance from a hole in the tundra, which resulted in impact with terrain.

NTSB narrative

The pilot of a tailwheel-equipped airplane reported that during the landing roll at a remote site, he was applying full engine power to taxi uphill. The airplane’s main landing gear wheels went into a low tundra hole and the airplane subsequently nosed over, sustaining substantial damage to the left wing lift strut. The pilot reported that there were no preaccident mechanical malfunctions or failures that would have precluded normal operation.
