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.
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.

- 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 2016-07-15.
