## Discrepancy

THE NR 3 ENGINE EGT HIT REDLINE ON TAKEOFF ROLL.  REDUCING EPR TO 1.4 FAILED TO KEEP EGT OUT OF REDLINE.  THE AIRCRAFT WAS RETURNED TO IAH WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND FITTING ON PRBC BROKEN.  THE PRBC WAS REPLACED IAW MM 75-31-13.  THE ENGINE WAS RUN AND EGT WAS WITHIN LIMITS.  A BORESCOPE HOT SECTION INSPECTION WAS PERFORMED AND NO DEFECTS WERE NOTED.
