What happened
Shortly after initiating takeoff, the aircraft experienced a sudden loss of engine power. The pilot made the decision to execute a forced landing in an area characterized by rough and uneven terrain. During the subsequent landing roll, the nose gear collapsed and broke off.
The investigation
Federal Aviation Administration inspectors examined the aircraft's fuel system following the incident. They discovered water contamination within the fuel strainer and the carburetor bowl. Further inspection of the fuel cap assembly revealed that the left cap was rusted around its seal, while the seal on the right cap had deteriorated.
Findings
The primary factor contributing to the accident was fuel exhaustion caused by water contamination. The compromised seals on the fuel caps allowed moisture to enter the system, leading to engine failure. The pilot's decision to land in rough terrain resulted in significant structural damage, including the loss of the nose gear.
Safety message
Regular inspection and maintenance of fuel cap seals are critical to preventing water contamination in aircraft fuel systems. Pilots should ensure that fuel caps are secure and undamaged before flight to avoid ingesting moisture into the engine.
