NTSB narrative
The pilot reported that the airplane would not climb out of ground effect during takeoff. The airplane settled into a corn field located off the end of the 3,100-foot-long asphalt runway. The left landing gear collapsed and the airplane nosed over resulting in substantial damage to the wings. The maximum certified gross weight of the airplane was 4,500 pounds with a basic empty weight of 3,093.8 pounds. The airplane was loaded with 80 gallons of fuel (480 pounds) and 170 gallons (1,419.5 pounds) of water/chemical mix. The pilot's weight was approximately 185 pounds. The airplane was approximately 678.3 pounds over the maximum gross weight at the time of the takeoff.
Probable cause
The pilot's failure to perform accurate weight and balance calculations which resulted in exceeding the maximum takeoff weight and the airplane's climb capability.

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, 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.
