## Discrepancy

DURING CRUISE AT 41,000 FEET, PILOT NOTICED THE RT ENG LOW OIL PRESSURE LIGHT COME ON FOLLOWED BY OIL QUANTITY DROPPING NEAR ZERO AND OIL PRESSURE DROPPING ALSO. IAW QRH, PILOT SHUT DOWN THE RT ENG AND DIVERTED. AFTER LANDING, THE MECHANICS FOUND OIL IN THE TAILPIPE AND THE 6QT OIL LEFT IN TANK . THE TAIL PLUG WAS REMOVED FOR CHECKING THE NR 5 BEARING COMPARTMENT. THE OIL SCAVENGE TUBE FOUND SLIGHT COKE. IT DID NOT DETECT ANY ABNORMAL DURING THE THEREAFTER GROUND RUNNING AND FERRIED BACK TAIWAN. THE P&W PRELIMINARILY SUGGESTED REMOVE LUBE SCAVENGE PUMP FOR INVESTIGATION.THIS ENG INSTALL ON THIS A/C, SINCE NEW AT BOEING, DID NOT REMOVE BEFORE.
