NTSB narrative
The agricultural spray airplane was destroyed by post impact fire after it impacted a power line and trees following a loss of engine power while departing from a 3,400 foot asphalt runway. The pilot reported that he had landed to refuel and take on chemicals. He reported that it was the sixth load of the day, and that the load was identical to the other five loads used previously. He reported that the airplane lifted off from the runway at the same place as the previous takeoffs. He reported that the "aircraft began to lose power about 10 ft. off the ground. There wasn't enough runway left to land so I dumped the load until I was close to the trees." He reported that he impacted the wires and settled into the trees that were located south of the runway. The airplane impacted the terrain and started to burn. The pilot reported that witnesses rescued him from the burning airplane. Tree limbs were found in the wreckage path that exhibited diagonal cuts and paint transfer marks that were consistent with propeller slashes. Fire damage to the engine precluded an inspection of the engine's ignition and fuel system.
Probable cause
The partial loss of engine power for an undetermined reason. Contributing factors were the wires and the trees.

- 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.
