Narrative:
The no. 3 propeller gearbox failed, causing the prop to separate. A broken propeller blade struck the no. 4 propeller, which also separated. A propeller then crossed under the aircraft slicing through the fuselage, cables, hydraulics and pressure vessel, damaging the no. 2 engine.
The no. 2, 3 and 4 engines were shut down. An emergency landing was carried out at Aruba with no brakes, 10deg flaps and limited flight controls.

PROBABLE CAUSE: "The in-flight loss of the nos 3 and 4 propellers and gearboxes for undetermined reasons. The failed components were not recovered from the Caribbean sea."
