## Discrepancy

THE FLIGHT CREW REPORTED THAT A PITCH FEEL FAIL AMBER CAS MESSAGE WAS DISPLAYED DURING FLIGHT. THEY REPORTED THAT THE MESSAGE WAS ILLUMINATED THROUGH AIRCRAFT SHUTDOWN. THE MAINTENANCE VENDOR TROUBLESHOT AND DETERMINED THE LEFT PITCH FEEL ACTUATOR WAS DEFECTIVE. THE DEFECTIVE ACTUATOR WAS REMOVED AND A OVERHAULED UNIT WAS INSTALLED. FUNCTIONAL CHECKS WERE SATISFACTORY. THE AIRCRAFT WAS THEN RETURNED TO SERVICE.
