## Discrepancy

THE FLIGHT CREW REPORTED THAT DURING CLIMB-OUT AFTER TAKEOFF THEY RECEIVED A RIGHT ENGINE PYLON OVERHEAT CAS MESSAGE. THE CREW RAN THE CHECKLIST AND WAS ABLE TO CLEAR THE FAULT. THE MAINTENANCE VENDOR TROUBLESHOT AND DETERMINED THE HIGH PRESSURE AIR DUCT P/N LJ01317-002 WAS LEAKING. A NEW TUBE ASSY WAS INSTALLED WITH NEW SEALS. LEAK CHECKS WERE SATISFACTORY AND THE AIRCRAFT WAS RETURNED TO SERVICE.
