## Discrepancy

(CAN) THE PILOT REPORTED THAT DURING CLIMB WHEN THEY SELECTED THE ENG/STAB ANTI-ICE "ON".  AFTER 2 MINUTES AND 45 SECONDS THEY GOT A SUPPLY BLEED LEAK RT CAS MESSAGE. THEY WERE ABLE TO CLEAR THE MESSAGE IAW THE PROCEDURE IN THE POH.  A SUBSEQUENT GROUND RUN WAS CARRIED OUT TO CHECK FOR BLEED LEAKS.  WE FOUND THAT AIR WAS LEAKING FROM THE WIGGIN COUPLING FOR THE LT & RT OZONE CONVERTERS.  FURTHER INVESTIGATION REVEALED NO EVIDENCE OF A SEAL, 2 EA, PN AS3209-226, ON EITHER THE LT OR RT UPPER WIGGINS COUPLING AND BADLY DETERIORATED SEALS, 2 EA, PN AS3209-222 ON EITHER THE LT & RT WIGGINS COUPLING.  ALL THE PACKINGS WERE REPLACED AND A SATISFACTORY GROUND RUN CARRIED OUT.  NO FURTHER LEAKS DETECTED.  THE EXCESSIVE AIR LEAK DISCOVERED DIRECTED HOT BLEED AIR ONTO THE RT SUPPLY BLEED LEAK SENSE LINE.
