## Discrepancy

FLIGHT 6102 CMH TO BOS, THE FLIGHT CREW RECEIVED A BLEED 1 LEAK MESSAGE AFTER TAKEOFF.  THE MESSAGE CLEARED WHEN THE NR 1 BLEED WAS TURNED OFF.  THE FLIGHT RETURNED TO KCMH AND LANDED WITHOUT INCIDENT.  WHILE TROUBLESHOOTING THE BLEED SYSTEM, THE BLEED LINE JUST TO THE LEFT OF THE CROSS BLEED VALVE WAS FOUND TO BE LEAKING.  THE O-RINGS WERE REPLACED AND THE SYSTEM LEAK CHECKED GOOD.
