Incident Overview
A pilot reported that while on final approach to the runway, he experienced turbulence and a sudden loss of altitude approximately 200 feet above the ground. In response, he added power but was unable to generate sufficient thrust to reach the runway. The airplane subsequently landed short, impacting a fence and an elevated road.
Post-Event Examination
An examination of the airplane revealed no pre-impact mechanical malfunctions. The aircraft had no known defects that could have contributed to the loss of power.
Pilot Statement
The pilot stated that the engine's inability to produce enough power was due to the mixture control being accidentally pulled out by a headset cable. He also reported that he had checked the mixture control during the base and final approach legs, implying that the disturbance occurred later or went unnoticed during those checks.
Conclusion
The incident highlights the interaction of cockpit equipment with flight controls, though no official cause has been determined beyond the pilot's account.
