## Discrepancy

CREW REPORTED THAT DURING CLIMB, IN ICING CONDITIONS, RECEIVED A "BLEED 1 LEAK" MESSAGE.  THE MESSAGE WENT AWAY AFTER THE BLEED 1 VALVE CLOSED.  THE CREW RETURNED TO KLGA AND LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE O-RING AT THE LEFT WING ROOT.  OPERATIONAL AND LEAK CHECKS OF THE BLEED SYSTEM WERE GOOD WITH NO FURTHER DEFECTS NOTED.
