## Discrepancy

(CAN) BULKHEAD CRACKS NEAR THE PROP BOLT ATTACH POINTS, SPINNER SUPPORT MATERIAL SEEMS TO BE TOO SOFT, IT ROTATES IN THE SPINNER, ALLOWING THE SPINNER TO VIBRATE AND CRACK THE BULKHEAD, ALL THE PROPER SHIMS AND INSTALLATION IS DONE WITH THE INSTRUCTIONS SUPPLIED. THIS IS THE 3RD BULKHEAD REPLACED ON THIS ACFT SINCE AUG/07, THIS ENG WAS OVERHAULED LAST SPRING, NO ENGINE VIBRATION REPORTED.
