ON TAKEOFF, DURING GEAR RETRACTION, FLIGHT CREW RECEIVED A WING ANTI ICE LEAK WARNING MESSAGE. A FEW SECONDS LATER THE WARNING MESSAGE WENT AWAY AND THEN THEY RECEIVED L WING ANTI ICE FAIL, R WING ANTI ICE FAIL, & L WING A/I PRESS HI CAUTION MESSAGES AND L ENG THRUST FAULT, R ENG THRUST FAULT, & ICE DETECTED ADVISORY MESSAGES, AS WELL AS YELLOW FLOW LINES ON THE ANTIICE SYNOPTIC PAGE WITH THE LEFT WING ANTI ICE VALVE AMBER. THE CREW IMMEDIATELY DEPARTED FROM ICING CONDITIONS. CONCURRENTLY, SMOKE BEGAN TO BE VISIBLE IN THE COCKPIT AND CABIN WHICH SMELLED OF GLYCOL BURNING. THE APU WAS SECURED WHILE SWITCHING BLEED SOURCES TO THE ENGINES. ONCE EXITING ICING CONDITIONS, THE CREW SECURED THE ANTI ICING SYSTEM. AN UNEVENTFUL LANDING WAS ACCOMPLISHED. EXTENSIVE TROUBLESHOOTING WAS ACCOMPLISHED AND SEVERAL ELECTRICAL CONNECTORS REPLACED ON THE LEADING EDGE BLEED LOOPS. THE SYSTEM WAS FUNCTIONALLY TESTED AND NO FAULTS WERE NOTED.

ON CLIMBOUT BEFORE 10,000', HEARD ENGINE POP, THEN MADE GRINDING NOISE WITH VIBRATION. FUEL FLOW AND ITT SLIGHTLY HIGHER IN AFFECTED ENGINE. REDUCED POWER ON AFFECTED ENGINE AND TOLD ATC THAT AIRCRAFT WAS HAVING AN ENGINE ISSUE AND RETURNING TO AIRPORT VFR. NO EMERGENCY DECLARED, KEPT ENGINE RUNNING ON REDUCED POWER. ENGINE SYNC FAIL (CYAN) CAS MESSAGE. LANDED & SHUTDOWN ENGINE UPON CLEARING RUNWAY. BORESCOPED HPC CORE AND FOUND NO DEFECTS BUT THE HP HOT AND FOUND HPT1 BLADES HAVE HEAVY DAMAGE. NO METAL NOR CHIP EVENTS FROM THE DOWNLOAD. I BELIEVE THE HPC CORE HAS LOCKED UP IN THE BACK END AND NOT CORE. THIS COULD BE REPAIRED OUT IN FIELD NOT REQUIRING AN ENG R&R” ORIGINAL ENGINE TO BE SENT IN FOR FURTHER EVALUATION AND REPAIR.
