Incident Overview
A delivery flight bound from California to Indonesia, with a planned refueling stop in Hawaii, experienced a dual engine failure while cruising approximately 370 kilometers off the coast of Hilo. The aircraft, being delivered to its new operator Zamrud Aviation, had departed California earlier.
Events Leading to Ditching
While en route, the crew contacted air traffic control to report engine problems. Shortly thereafter, they made the decision to ditch the aircraft in the ocean. The crew executed a controlled ditching, and all three occupants were quickly rescued by awaiting emergency services. The aircraft subsequently sank and was lost.
Probable Cause
The official investigation determined the probable cause to be failure of both engines due to a malfunction of the lubricating system. The loss of oil pressure occurred for an undetermined reason.
