## Discrepancy

ORD - FLT 5972 - THE CREW REPORTED A BLEED 1/2 LEAK MESSAGE ON THE EICAS ON FINAL APPROACH.  THE CREW DECLARED AN EMERGENCY AND LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE INSPECTED AND REPLACED THE O-RING AT JOINT 15 OF THE BLEED AIR SYSTEM AND RE-SECURED THE DUCT.  OPERATIONAL CHECKS WERE GOOD.
