What happened
During a ferry mission from California to Indonesia, a crew was operating a flight via Hawaii to deliver an aircraft to its new operator, Zamrud Aviation. While the aircraft was maintaining cruise altitude approximately 370 km away from Hilo, the flight crew reported significant engine issues to Air Traffic Control. Due to the nature of the mechanical difficulties, the decision was made to perform an emergency ditching in the ocean.
Following the impact with the water, all three occupants were successfully recovered by rescue teams. The aircraft type was lost following the incident as it sank beneath the surface.
Findings
Investigations into the accident determined that both engines suffered a failure. This loss of power was attributed to a malfunction within the lubrication system, which resulted in a drop in oil pressure for reasons that remain undetermined.
