## Discrepancy

DURING CRUISE FLIGHT 'AP TRIM NOSE DOWN' CAS MESSAGE ILLUMINATED, AUTOPILOT WAS DISCONNECTED. MANUAL AND ELECTRIC TRIM WAS FROZEN AND INOPERATIVE. DESCENDING TO A LOWER ALTITUDE RESOLVED THE FROZEN TRIM ISSUE. AIRCRAFT CONTINUED TO DESTINATION. LANDING WAS UNEVENTFUL. MAINTENANCE REPLACED THE LEFT AND RIGHT ELEVATOR TRIM ACTUATORS. NEW ACTUATORS WERE LUBED AND THE CONTROL ROD ENDS ON THE RIGHT TRIM ACTUATOR WERE ADJUSTED. A SUCCESSFUL OPERATIONAL CHECK FLIGHT WAS PERFORMED. AIRCRAFT WAS RETURNED TO SERVICE. LEFT ACTUATOR S/N OFF: 52372890-001, RIGHT ACTUATOR S/N OFF: 52365615-003
