Probable cause
The pilot's failure to maintain directional control during landing in variable wind conditions, which resulted in the right wing impacting muddy terrain.
Findings · 3
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
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 the tailwheel-equipped airplane reported that, during the landing roll, the tail "lifted back up" due to a "wind gust" and that the airplane then veered left, spun, exited the runway, and the right wing impacted muddy terrain. The airplane sustained substantial damage to the right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot reported the wind was light and variable at 5 knots. An automated weather observation station located about 15 nautical miles from the accident site reported that, about 30 minutes before the accident, the wind was from 150° at 4 knots and that, about 30 minutes after the accident, the wind was from 120° at 5 knots. The pilot landed the airplane on runway 30.
