NTSB narrative
The airplane collided with terrain following a loss of control on takeoff. The pilot reported that he was taking off with a full load of fuel and chemicals when the accident occurred. He stated that the airplane lifted off and climbed to an altitude of about 500 feet when it began to settle to the ground. The airplane landed in a bean field and contacted a ditch. The pilot stated that he did not have time to dump the chemical load prior to impacting the ground. The takeoff was being made on a 2,000 foot long, grass airstrip.
Probable cause
The pilot's inability to maintain a proper rate of climb during takeoff. Factors associated with the accident were the pilot's failure to dump the chemical load and the ditch which the airplane contacted.

- 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. 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.
