ENGINE WAS SECURED AND THE AC LANDED WITHOUT INCIDENT. MAINTENANCE INSPECTED THE AIRCRAFT AND FOUND NO OBVIOUS PROBLEMS. ATTEMPTED TO START. DID NOT SEE A RISE IN NR 2, ENGINE WOULD NOT START. MUCH METAL FOUND IN FILTERS.  ACCESSORY GEAR BOX WAS NOT SPINNING.  ENGINE REMOVED AND REPLACED. GEAR BOX INPUT'S ROTATE, BUT NO ACCESSORY GEARS TURN.
