Incident
Approximately 5 hours and 10 minutes after departure, both engines of the aircraft failed at an altitude of 11,000 feet about 40 miles from Haiti. The pilot reported that the aircraft was consuming more fuel than normal, prompting a change in the destination. Shortly after initiating the diversion, both engines quit. The crew performed an emergency landing in the sea approximately 64 kilometers off Port-de-Paix and was rescued. The aircraft was lost.
Investigation
The official investigation determined that the loss of engine power was nonmechanical and occurred during the normal cruise phase of flight. Findings included inadequate fuel consumption calculations by the pilot in command, delayed action by the pilot in command, and fuel exhaustion as the cause of the power loss. A forced landing was performed during an emergency descent, followed by a ditching during the landing roll.
Probable Cause
The probable cause was loss of engine power due to fuel exhaustion resulting from inadequate fuel consumption calculations by the pilot in command and delayed action.
