## Discrepancy

DURING CLIMBOUT, THE CREW NOTICED THAT THE ELEVATOR TRIM STOPPED WORKING.  AFTER CONFERRING WITH MAINTENANCE CONTROL, FLIGHT 4156 RETURNED TO DAY.  MAINTENANCE INSPECTED AND REPLACED THE 49CC RELAY IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 27-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS THEN RELEASED FOR SERVICE.
