## Discrepancy

CREW REPORTED ON APPROACH THE RT LOW OIL PRESSURE ANNUNCIATOR ILLUMINATED AND OIL PRESSURE INDICATED 60 PSI. ENGINE CONTINUED TO SHUT ITSELF DOWN. EMERGENCY DECLARED AND AIRCRAFT LANDED SAFELY. MAINTENANCE CONFIRMED METAL IN OIL FILTER. POWER SECTION TEARDOWN RESULTS FROM MFG SHOW OIL NOZZLE FOR NR 3 AND NR 4 BEARINGS FOUND COKED. PROBABLE CONTRIBUTING FACTORS WERE INCOMPLETE CLEANING OF OIL JET LUBRICATING TUBE DURING LAST OVERHAUL AND HIGH BEARING COMPARTMENT TEMPERATURE OF NOZZLE.
