NTSB narrative
The pilot stated that he was landing with a left quartering headwind. He reported that the touchdown was normal, but as he lowered the tail wheel, the aircraft weathervaned to the left into the wind. He applied full right pedal and initiated a go-around. The aircraft left the ground, turned downwind and lost lift. The airplane impacted the drainage ditch area parallel to the runway. There are drainage ditches and levees spanning the entire length on both sides of the runway. The ditches are approximately 6 to 8 feet deep and 12 feet wide, and are about 90 feet from the runway centerline. The levees are approximately 20 feet beyond the ditches. FAA Advisory Circular AC 150/5300-13, regarding runway and taxiway design, indicates the Object Free Area for the accident airport to be 200 feet on either side of the runway centerline. The AC requires the Obstacle Free Zone to be 125 feet on each side of the runway centerline, and states that obstacles within that zone cannot be higher than 3 inches above grade; the sides of the ditches and levee rise about 3 feet above grade.
Probable cause
The failure of the pilot to adequately compensate for the wind conditions and to maintain directional control of the aircraft while landing. A factor is the airport's failure to follow proper procedure in ensuring adequate obstacle and object free clearance around the runway.

- 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. 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.
