## Discrepancy

CVG TO GSP - DURING CLIMB, THE CREW RECEIVED A BLEED 2 LEAK MESSAGE ON EICAS.  THE AIRCRAFT THEN RETURNED TO FIELD AND LANDED WITHOUT INCIDENT.  MAINTENANCE RAN THE BLEEDS AND INSPECTED FOR LEAKS.  A LEAK WAS FOUND AT JOINT 4 AND AFTER REPLACING THE O-RINGS AT JOINT FOUR THERE WERE NO FURTHER LEAKS FOUND.
