## Discrepancy

(CAN) DURING FLIGHT, PILOT NOTICED THE ELEVATOR TRIM WHEEL, FREEWHEELING, WITH NO CONTROL OF THE ELEVATOR TRIM TAB, NO UNCONTROLLED MOVEMENT OF THE ELEVATOR TRIM TAB REPORTED. UPON INSPECTION FOUND THE ACTUATOR SPROCKET SHEARED WITH SPROCKET AND CONTROL CABLES LAYING IN HORIZONTAL STAB, EXPLAINING THE LOSS OF CONTROL. AFFECTED PARTS WERE REPLACED SATISFACTORY.
