## Discrepancy

DURING A SCHEDULED INSPECTION IT WAS FOUND THAT ONE OF THE HORIZONTAL STABILIZER MOUNT BOLTS HAD BEEN SHEERED IN HALF.  CLOSER INSPECTION FOUND THE BOLT WAS SEVERELY CORRODED.  THE OTHER THREE MOUNT BOLTS WERE REMOVED AND EXAMINED, ALL WERE CORRODED.  A FLEET CAMPAIGN DIRECTIVE WAS INITIATED TO INSPECT AND REPLACE THE BOLTS.
