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

While on final approach to the destination runway, the pilot noted that the windsock indicated a variable crosswind. The airplane touched down normally, in a tail-low configuration with the upwind-wing lowered to accommodate the crosswind. As the airplane was on the landing roll it passed by a hangar, where the pilot maneuvered the controls to adjust for the sudden no-wind condition. Just prior to the tailwheel making contact with the runway surface, the airplane passed a gap between two hangars and correspondingly encountered a gusty crosswind. The airplane partially ground-looped, with the right wing contacting the surface. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane. A routine aviation weather report (METAR) for the airport, issued around the time of the accident, reported winds from 230 degrees at 03 knots.

The airplane partially ground-looped, with the right wing contacting the surface. The pilot reported that there were no pre impact mechanical malfunctions or failures with the airplane. As a result of the accident, the airplane incurred damage to the right wing.
