## Discrepancy

(CAN) DURING ANNUAL INSPECTION THE IB FORWARD AUX FIN ATTACH BOLT WAS FOUND SHEARED AT THE HEAD.  IT APPEARS THAT THE FIN WAS INSTALLED WITH A PRE LOAD CAUSING THE BOLT TO FAIL.  SUB-CONTRACTOR HAS BEEN NOTIFIED OF THIS OCCURRENCE AND IS CURRENTLY INVESTIGATING THE REQUIREMENT FOR A SHIM INSTALLATION.  THE REMAINING ATTACH BOLTS WILL BE REMOVED FOR NDT INSPECTION TO ENSURE THE SERVICEABILITY OF THE BOLTS PRIOR TO RE-INSTALLATION.
