Incident Overview
A turbine-powered agricultural airplane experienced a loss of engine power during a fertilizer application operation over pine trees. The pilot reported that no open areas were available for a forced landing, and the airplane subsequently settled into the pine trees.
Fuel System Examination
Post-incident inspection of the airplane's fuel system revealed it was three-quarters full, with fuel present in the lines leading to the engine. The operator noted that three other aircraft under his supervision had been refueled from the same tanker and none reported any issues with fuel contamination.
Engine Configuration
The engine was not equipped with an automatic re-light or continuous ignition system. Despite the fuel system appearing normal and no evidence of contamination, the specific reason for the engine power loss could not be determined.
Conclusion
Investigators were unable to identify a definitive cause for the loss of engine power during the flight.
