The aircraft crashed a during a landing attempt. Loss of power in both starboard engines resulting in control difficulties. Fuel starvation due to inadvertent fuel transfer. Inadvertent fuel transfer in flight on a scale sufficient to involve the risk, after a long flight, of emptying the tank expected to contain sufficient fuel can occur if the fuel selector levers in the cockpit of this type of aircraft are incorrectly positioned by even a small amount. This is easy to do and difficult for the pilot to recognize.
