What happened
The pilot had previously executed a forced landing in a field due to a malfunctioning fuel selector valve. After addressing the mechanical issue by repairing the valve, the pilot attempted to resume flight from County Road 240. During the initial climb phase, at an altitude of approximately 3 feet, the engine sputtered and lost power. The pilot was unable to maintain control of the aircraft, which veered to the left. The right wing struck a fence post and was severed, resulting in a crash.
The investigation
The investigation focused on the mechanical failure that led to the initial forced landing and the subsequent repair attempt. The primary issue identified was a stuck fuel selector valve, which prevented proper fuel flow to the engine. The pilot's decision to repair the valve in the field and immediately attempt takeoff from an unprepared surface contributed to the sequence of events.
Findings
The critical factors leading to the accident were the initial failure of the fuel selector valve and the subsequent loss of engine power during the takeoff roll. The low altitude at which the engine sputtered left insufficient time or height for recovery. The pilot's control was lost as the aircraft veered off the intended path, leading to structural failure upon impact with a stationary object.
Safety message
This incident highlights the risks associated with field repairs of critical flight controls and systems. Attempting to resume flight from an unprepared surface after a mechanical failure requires careful assessment of the repair's reliability and the surrounding environment. Pilots should consider the limitations of in-field maintenance and the potential for residual issues affecting engine performance.
