NTSB narrative
The solo pilot was landing at a remote gravel airstrip. The pilot stated that prior to landing he had received a pilot report indicating that there was a slight breeze, favoring a landing to the east. He looked at the airstrip windsock, noted that it was hanging limp, and prepared to land to the west. He said that while landing to the west, and just after touchdown, a gust of wind from behind pushed the tail of the airplane to the left. The airplane veered to the right, and went off the right side of the runway and came to rest in a ditch that borders the runway. He said that his decision to land to the west was based on a more favorable approach, and it would eliminate the need to back taxi.
Probable cause
The pilot's inadequate compensation for wind conditions while landing. A factor associated with the accident was the presence of a tailwind condition.

- 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.
