Incident Overview
A pilot departed Fort Pierce, Florida, for Wilmington International Airport in North Carolina. While cruising at 7,000 feet, the engine "coughed" and dropped to idle power. The pilot declared an emergency with Air Traffic Control and was cleared to land at Saint Simons Island airport. However, the aircraft could not reach the runway and was ditched in the water.
Aircraft and Engine Examination
Post-accident examination revealed the engine had minor damage. The oil filter and oil were replaced in preparation for an engine run. Examination of the left and right magnetos found that they would not produce spark when rotated. Internal inspection of both magnetos showed salt water corrosion. After replacing the magnetos, the engine was run and produced nearly full power despite slightly bent propeller blades.
Pilot Actions and Procedural Considerations
The pilot stated that after the engine failed, he switched the fuel tank selector positions but did not activate the electric fuel pump. According to the source, although the cause for the loss of engine power remains undetermined, it is likely that following the emergency procedures in the Pilot Operating Handbook—specifically activating the auxiliary fuel pump after switching tanks—would have allowed the engine to restart. No further causal determination was provided.
Conclusion
The investigation did not determine a definitive cause for the initial engine power loss. The ditching occurred after the aircraft was unable to reach Saint Simons Island airport. No injuries or fatalities were reported in the source.
