## Discrepancy

THE CREW REPORTED THAT DURING CRUISE FLIGHT AT FL 380 THE AUTO-TRIM ANNUNCIATOR ILLUMINATED.  AFTER DISCONNECTING THE AUTO-PILOT THE TRIM WHEEL WAS FOUND TO BE STUCK.  THE TRIM WHEEL BECAME EASIER TO MOVE DURING DESCENT AT A LOWER ALTITUDE.  OPERATION ON THE GROUND AFTER THE FLIGHT WAS NORMAL.  MAINTENANCE ACCOMPLISHED A SATISFACTORY ELEVATOR TRIM STATIC FRICTION CHECK.  A SATISFACTORY FUNCTIONAL TEST WAS PERFORMED ON THE ELEVATOR TRIM CONTROL SYSTEM.  THE LEFT AND RIGHT ELEVATOR TRIM JACKS WERE CHECKED AND LUBRICATED.  THE AIRCRAFT WAS RETURNED TO SERVICE.
