## Discrepancy

DURING A SCHEDULED MAINTENANCE VISIT WHILE PERFORMING A HORIZONTAL STABILIZER ROLLER BRACKET INSPECTION AS PART OF THE 'B' LEVEL INSPECTION THE LEFT INBOARD HORIZONTAL STABILIZER NOSE RIB STRUCTURE WAS FOUND CRACKED NEXT TO THE SIDE ROLLER ATTACH BRACKET.  DETAILED INSPECTION INSTRUCTIONS OF THIS AREA ARE OUTLINED IN BEECHJET COMMUNIQUÉ' NUMBER 70.  THE HORIZONTAL STABILIZER ASSEMBLY WAS REMOVED AND THE LEFT INBOARD LEADING EDGE ROLLER SUPPORT RIB WAS REPLACED IN ACCORDANCE WITH THE BEECHJET STRUCTURAL REPAIR MANUAL.  THE HORIZONTAL STABILIZER WAS REINSTALLED TO THE AIRCRAFT.  SATISFACTORY RIGGING AND OPERATIONAL CHECKS WERE COMPLETED FOLLOWING THE INSTALLATION.  THE AIRCRAFT WAS RETURNED TO SERVICE.
