What happened
The aircraft departed for an agricultural operation carrying a load of 160 gallons of chemical herbicide. At the time of departure, the fuel tanks were only half full. During the initial climb phase after takeoff, the pilot reported a sudden loss of engine power. Unable to maintain altitude or continue the flight, the pilot initiated a forced landing procedure and directed the aircraft toward a nearby road.
The investigation
A subsequent examination of the aircraft was conducted by an FAA inspector to determine the mechanical cause of the power loss. The inspection focused on the fuel system components and controls. The findings indicated that there were no signs of fuel contamination within the system. Additionally, records and physical checks confirmed that the fuel boost pump had been operated within its normal limits and all fuel controls were positioned correctly for flight.
Findings
Despite the thorough inspection, investigators could not determine the specific reason for the loss of engine power. The mechanical components appeared to be functioning as intended based on the post-accident examination. The pilot successfully managed the emergency by executing a forced landing, preventing more severe consequences despite the unexplained mechanical failure.
