MAINTENANCE REMOVED AND REPLACED RIGHT ENGINE. THE NR 2 SCAVENGE OIL FILTER WAS FULL OF METAL. THE TEAR DOWN REPORT DID NOT REVEAL THE SOURCE OF THE METAL CONTAMINATION. THE DAMAGE TO THE NR 14 BEARING AND PROPELLER BRAKE COUPLING APPEARS TO BE SECONDARY MECHANICAL DAMAGE AND INDICATE THAT THE METAL FOUND ON THE CHIP DETECTOR MOST LIKELY ENTERED THE REDUCTION GEAR BOX AT THIS POINT WHERE THE MAJORITY OF MECHANICAL DAMAGE WAS FOUND.
