## Discrepancy

ENGINE MOUNT PLATE AND SHIM WERE FOUND CORRODED UNDER THE AREA OF THE LEFT AND RIGHT ENGINE MOUNT TO FIREWALL ATTACHMENT.  THE SHIMS WERE FLAKING AWAY SEVERELY AND IF LEFT UNREPAIRED, WOULD CAUSE THE MOUNT TO FIREWALL BOLT TORQUE TO DROP. THESE PARTS SHOULD BE MADE OF STAINLESS STEEL.
