This is preliminary information, subject to change, and may contain errors. The foreign authority was the source of this information.

About 5 minutes after takeoff, a propeller blade separated adjacent to the propeller hub of the number 2 (right) engine. The crew felt high vibrations in the airplane and the number 2 engine's low oil pressure warning light illuminated. When the pilots attempted to shut down the engine, the fuel lever jammed. They then shut the engine down by pulling the fire handle. The airplane returned to Caratagena for an emergency landing. There were no injuries or additional damage resulting from the landing. The airplane sustained minor damage to the number 2 engine's cowling and an adjacent propeller blade was fractured at about the midspan area. Examination of the engine revealed that both of the forward engine mounts had broken and the engine sagged to the bottom of the engine cowling.

Examination of the fractured propeller blade end revealed that blade separation resulted from a fatigue fracture near the base of the blade. Corrosion was found at the fracture sight.

On February 1, 2002, the propeller manufacturer (Hamilton Sundstrand) issued Alert Service Bulletin 568F-61-A33, "Propellers-Blades-Removal of 568F Propeller Blades from Service," which requires that propeller blades serial numbers 1 to 1698 be removed from service and inspected.

On February x, 2002, the Safety Board issued two safety recommendtaions(A-02-XX and -XX) to the FAA on the subject blade inspections, repairs, and modifications.

The Aeronautica Civil-Colombia is conducting the investigation of this incident.
