Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

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.

Factual narrative

During a trans-Pacific ferry flight from California to Hawaii the pilot reported that he lost engine power as a result of fuel exhaustion and ditched in the Pacific Ocean approximately 7 nm Northeast of Hilo, Hawaii. The pilot departed California with approximately 393 gallons of fuel, which he calculated to be approximately 14 hours of fuel endurance. The pilot reported that about 9 hours after takeoff he determined that due to a change in the wind velocity he would not reach his destination. The pilot attempted to extend his range by reducing his fuel consumption, but was unable to make his intended destination. After ditching the pilot exited the airplane and was rescued by the US Coast Guard. The airplane sank shortly after the pilot was rescued. The total duration of the flight was approximately 13 hours.
