## Discrepancy

WHILE ACFT WAS PASSING THRU 26000 FT THE NR 3 ENG BEGAN TO COMPRESSOR STALL.  CREW PERFORMED APPROPRIATE PROCEDURES AND RETURNED TO DEPARTURE WHERE IT LANDED WITHOUT INCIDENT.  POST FLIGHT INSP WAS PERFORMED.  THE NR 3 ENG PRBC WAS REMOVED AND REPLACED.  WHILE REPLACING THE PRBC IT WAS NOTED THAT THE BLEED CONTROL HIGH PRESSURE AIR SUPPLY TUBE WAS BROKEN AT THE B-NUT.  LINE WAS REMOVED AND REPLACED, OPS AND LEAK CHECKS WERE GOOD.  NO OTHER DEFECTS WERE NOTED.  ACFT WAS RETURNED TO SERVICE.
