Event Description
During the climb after takeoff, the engine experienced a substantial loss of power. The pilot reported that he did not have time, airspeed, or altitude to turn. The airplane subsequently impacted the top of a tree line, a residential structure, a fence, and a propane tank before coming to rest.
Pilot Report
The pilot stated that the takeoff run was uneventful. He reported that the airplane was loaded with 120 gallons of a chemical mixture and was within the weight and balance limitations for the aircraft.
Investigation Findings
Examination of the wreckage revealed no anomalies with the airframe and the flight control system. The fuel pump was tested and was found to be outside the manufacturer'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.
