Probable cause

The pilot’s failure to maintain runway alignment during landing in gusting crosswind conditions, which resulted in an off-runway landing in soft dirt and a nose-over.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot of a tailwheel-equipped airplane reported that, during short final approach in gusting wind conditions, the airplane drifted left. The airplane landed left of the runway in soft dirt and nosed over. The airplane sustained substantial damage to the right wing lift struts. The pilot reported that, about 10 minutes before the accident, the wind was reported as light and variable at the airport. The airplane was landing on runway 7R. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
