NTSB narrative
The pilot stated that the takeoff run was uneventful, but during the climb the engine experienced a substantial loss of power. The pilot reported that he did not have, '... time, airspeed, or altitude to turn.' The airplane impacted the top of a tree line, a residential structure, a fence, and a propane tank before coming to rest. Examination of the wreckage revealed no anomalies with the airframe and the flight control system. The pilot reported that the airplane was loaded with 120 gallons of a chemical mixture and was within the weight and balance limitations for the aircraft. The fuel pump was tested and was found to be outside the manufacture's limitations. The maximum allowable fuel pressure, at 2,700 rpm and 39.5 inches of mercury, is 37.0 psi. The fuel pump from the accident airplane was bench-tested and yielded 60 psi.
Probable cause
the improper adjustment of the fuel pump by maintenance personnel. Factors to the accident were the excessive output of the fuel pump, trees, residential structure, fence, and propane tank.

- 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.
