NTSB narrative
The pilot reported that he landed with a gusting crosswind of 18 to 27 knots. At the end of the runway he made a 180 degree turn to back-taxi to the intersection for the ramp. During the back-taxi, the airplane veered to the right. The pilot applied the left brake, but it did not have enough braking action to stop the turn. The pilot also applied left rudder control and increased power for more rudder authority, but the airplane subsequently departed the runway pavement. The right main gear leg folded under the fuselage, the nose dug into the dirt breaking the wooden propeller, and the right wing tip contacted the ground. Postaccident examination of both the left and right brake systems revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. Fluid was found in both master cylinder reservoirs. Pedal pressure was even, firm, and normal. When brake pedal pressure was applied, both left and right calipers compressed against the rotors and released normally. Given the gusting crosswind, the wind likely led to the pilot’s loss of directional control.
Probable cause
The pilot's failure to maintain directional control while taxiing with a gusting crosswind.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2011-11-19.
