NTSB narrative
The pilot was returning from the completion of his 28th aerial application flight on the day of the accident. He stated that he misjudged the touchdown point for the landing and landed short of the dirt runway, striking a levee. He said that he had been working a full schedule all week and there was no doubt that he was “somewhat” tired, but he believed that a wind change “had more to do with the accident than any other factor.”
Probable cause
The pilot’s failure to attain the proper touchdown point, which resulted in a landing undershoot.

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. 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.
