Probable cause
The pilot’s failure to maintain directional control during the landing roll in gusting wind conditions.
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
According to the pilot in the tailwheel-equipped biplane, he was unable to determine the wind direction during his approach. He circled the airport multiple times and attempted to communicate on the common advisory traffic frequency. During the landing roll on the runway, the biplane experienced an "unexpected turn to (the) left similar to being weathercocked." The biplane exited the left side of the runway and continued across descending terrain before it nosed over. The METAR nearest to the accident airport reported that, about the time of the accident, the wind was from 170° at 16 knots, gusting to 19 knots. The biplane sustained substantial damage to both wings and the rudder. The pilot reported that there were no preaccident mechanical malfunctions or failures with the biplane that would have precluded normal operation.
