## Discrepancy

THE FLIGHT CREW REPORTED THAT DURING CLIMB OUT AFTER TAKEOFF THE RIGHT ENGINE PYLON OVERHEAT CAS MESSAGE OCCURRED TWICE. DUE TO THIS FAULT THE FLIGHT CREW ELECTED TO RETURN BACK TO THE AIRPORT AND LAND. THE MAINTENANCE TEAM DETERMINED A LEAKING PYLON BLEED AIR DUCT CONNECTION. THE DUCT CONNECTION SEAL WAS REMOVED AND REPLACED WITH NEW. OPS CHECKS AND LEAK CHECKS WERE SATISFACTORY AND THE AIRCRAFT WAS RETURNED TO SERVICE
