NTSB narrative
The pilot reported that he was taking off from his private airstrip with a left quartering tailwind for an aerial application flight. Due to payload and wind conditions, flying airspeed was not attained prior to his anticipated liftoff point. The nose of the airplane began to veer to the left, and he attempted to correct the drift. He passed his decision point and attempted to avoid a ditch in his path. The airplane impacted the northern bank of the ditch, shearing off the landing gear and damaging the propeller and spray system. After the airplane came to rest, the pilot egressed and a postaccident fire destroyed the wreckage. The pilot reported no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Probable cause
The pilot’s improper decision to attempt a takeoff with a quartering tailwind and his failure to reject the takeoff in a timely manner, which resulted in a runway excursion.

- 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, cause areas. 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.
