Probable cause
The pilot's failure to maintain directional control of the airplane 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
The pilot reported that while on final approach a crosswind gust pushed the nose of the airplane to the left. The pilot corrected back to the runway centerline and after landing "...a wind gust turned the tail and accelerated a right turn or a ground loop. The left wing touched the ground and the left gear collapsed." The undercarriage of the airplane where the left main gear attaches to the fuselage sustained substantial damage.
Factual narrative
The pilot reported that while on final approach a crosswind gust pushed the nose of the airplane to the left. The pilot corrected back to the runway centerline and, after landing, a wind gust turned the tail and the airplane ground-looped. During the ground loop, the left wing touched the ground and the left gear collapsed. The undercarriage of the airplane where the left main gear attaches to the fuselage sustained substantial damage.
