Probable cause
The pilot's failure to maintain directional control during the landing roll in gusty wind conditions, which resulted in runway excursion and impact with 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 as the tail came down during the landing roll in gusty wind conditions, a wind gust lifted the airplane about 10 feet into the air, with the left wing high. The pilot further reported that the airplane drifted off the runway to the right and impacted the ground right wing first. The airplane sustained substantial damage to the fuselage, both wings, and the empennage. According to the pilot there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. A review of recorded data from the automated weather observation station located about 5 miles to the southeast, revealed that, about 7 minutes before the accident occurred, conditions were wind 300 degrees true at 13 knots, wind gust 18 knots.
