NTSB narrative
The pilot reported that the engine lost power about 12 miles from the airport due to fuel exhaustion, and he ditched the airplane in the Pacific Ocean. The pilot had completed a preflight inspection for the transpacific flight and departed with approximately 393 gallons of fuel, which he calculated to be about 14 hours of fuel endurance. He reported that about 9 hours after takeoff he determined that, due to a change in the wind velocity, he would not reach his destination. He attempted to extend his range by reducing the airplane’s fuel consumption, but was unable to reach the airport. The pilot was rescued, and the airplane sank shortly thereafter. The total duration of the flight was about 13 hours.
Probable cause
A total loss of engine power during cruise flight due to fuel exhaustion as a result of the pilot’s improper fuel planning.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2011-10-08.
