NTSB Factual Report

The pilot reported that while he was taxiing the tailwheel-equipped airplane from the taxiway to the runway to conduct a takeoff in gusty wind conditions, the airplane’s left wing suddenly raised up. Despite pilot control inputs, the wing continued to rise and the airplane subsequently nosed over. The airplane sustained substantial damage to the tail and wing lift struts. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operations.

NTSB Probable Cause

The pilot's failure to maintain airplane control while taxiing in gusting wind conditions.
