## Discrepancy

DURING TAXIOUT (AMS), THE NR 3 ENGINE EXPERIENCED A COMPRESSOR STALL WITH HIGH EGT, LOSS OF OIL PRESSURE, AND SMOKE WAS REPORTED COMING FROM THE TAILPIPE.  THE FIRE HANDLE WAS PULLED AND THE BOTTLES WERE DISCHARGED.  A BOROSCOPE AND INSPECTION OF THE ENGINE CHECKED OK.  THE FIRE BOTTLES WERE REPLACED AND A FULL POWER RUN-UP CONFIRMED PROPER ENGINE OPERATION.  THE ENGINE IS SCHEDULED FOR REPLACEMENT.
