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 airplane, during the landing roll with the tailwheel on the ground, the airplane may have encountered a wind gust. The airplane exited the runway to the left, and the left main landing gear struck a taxiway sign. The airplane sustained substantial damage to the left main landing gear attachment points, the lower fuselage longeron, and the elevator. The pilot reported that the wind at the airport about the time of the accident was variable at 4 knots and that skies were clear. The nearest METAR to the accident site, located 11 miles to the west, reported that, about the time of the accident, the wind was from 270° at 8 knots with lightning in the distance to the northwest. The pilot landed the airplane on runway 35. The pilot reported that the accident could have been prevented if he had more quickly applied corrective actions, including increasing right rudder pedal pressure, using more differential braking, and increasing right aileron input. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
