NTSB narrative
The commercial pilot performed a preflight inspection and sampled the fuel with no anomalies noted. He then departed on the flight with 5 hours of available fuel. About 3.5 hours into the flight, the airplane was flying about 500 ft over the ocean when the engine experienced a total loss of power. The pilot performed a forced landing to the water, subsequently egressed, and was rescued a brief time later. Examination of the engine after recovery revealed no obvious signs of mechanical anomalies with the engine that would have precluded normal operation.
Probable cause
A total loss of engine power for reasons that could not be determined during a postaccident examination of the airframe and engine.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
