NTSB narrative
The pilot reported that he was departing from a gravel township road for an aerial application flight. During takeoff, he lowered the left wing to compensate for a crosswind. The left spray boom hit a buildup of dirt that was concealed by tall grass on the side of the road. This resulted in the airplane veering off the left side of the road and into a ditch which caused substantial damage to the wing and fuselage. The pilot reported that there was no mechanical malfunction or failure of the airplane.
Probable cause
The pilot's inadequate inspection of the takeoff area which resulted in a collision with terrain and the subsequent loss of control during takeoff.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2011-07-14.
