## Discrepancy

DURING CLIMB, THE NR 3 ENGINE NACELLE TEMPERATURE PEAKED AND THE ENGINE FIRE WARNING ACTIVATED.  THE ENGINE WAS SHUTDOWN, THE FIRE BOTTLES WERE DISCHARGED, AND THE AIRCRAFT RETURNED TO NRT WHERE AN UNEVENTFUL LANDING WAS ACCOMPLISHED.  THE HIGH STAGE BLEED VALVE AND CONTROLLER WERE REPLACED AND A RUNUP CONFIRMED PROPER ENGINE OPERATION.
