Probable cause
The total loss of power in both engines during cruise flight for reasons that could not be determined because the airplane was not recovered from the ocean.
NTSB narrative
The commercial pilot was conducting a personal, cross-country, overwater flight in the multiengine airplane with another commercial pilot on board, who was the nonflying pilot. The pilots reported that, at departure, both of the fuel gauges indicated 3/4 tank. While in cruise flight at 5,500 ft, both engines began running roughly; however, after descending the airplane to 3,500 ft, both engines seemed to smooth out. Shortly thereafter, the right engine surged and lost power, followed by the left engine surging and losing power. The pilots reported that they turned on both auxiliary fuel pumps and followed the emergency checklist but that power was not restored to either engine. They added that, at the time of the power loss, the fuel gauges indicated 1/2 tank. The pilot subsequently ditched the airplane in the ocean, and both pilots successfully evacuated the airplane. The airplane was unable to be recovered, which prevented any examination; therefore, the cause of the loss of engine power could not be determined.
Analysis
- Primary failure mode
- Engine power loss
- First missed decision gate
- Check fuel levels and engine performance before departure to prevent power loss.
