NTSB narrative
The pilot reported that, upon touchdown, the tailwheel-equipped airplane's right brake "locked up" and the airplane then veered off the right side of the runway. The airplane struck a 3-foot-wide drainage ditch about 66 feet from the edge of the runway, which resulted in substantial damage to the left wing. The examination of the accident site revealed runway skid marks and a wingtip scrape, which indicated that the right wheel was not on the ground until shortly before it contacted the ditch. The right brake successfully passed the acceptance test procedure with no visual indication of fluid leakage around the piston. The pilot had 997 total flight hours with 1 hour logged in the accident airplane. The accident flight was the first flight he had in the airplane, and it was his first landing in the accident airplane. The surface weather observation at an airport located about 18 nautical miles from the accident site indicated the wind was 320 degrees at 9 knots. The airplane landed on the runway at 280 degrees, which indicates that a 6-knot crosswind existed at the time of the accident.
Probable cause
The pilot’s failure to maintain directional control of the airplane while landing in a crosswind.

Source notes (4)
- 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: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
