What happened
The aircraft was operating in cruise flight during nighttime conditions when it experienced a complete loss of engine power in mid-air. In response to the emergency, the pilot initiated a forced landing procedure and targeted a nearby highway for touchdown. During the landing roll along the curved roadway, the airplane struck a tree situated adjacent to the road.
The investigation
Following the incident, an FAA coordinator examined the aircraft and discovered water contamination within the fuel system. This finding provided critical insight into the mechanical state of the engine prior to the failure.
Findings
The pilot reported that the engine had been running roughly several times throughout the day during the cross-country flight, indicating progressive performance issues before the total power loss occurred. The presence of water in the fuel system is a significant factor in this event.
Safety message
Fuel contamination, particularly water ingress, can lead to rough engine operation and eventual power failure. Pilots should be vigilant for signs of fuel system issues during flight.
