### TITLE: REPLACEMENT OF CF6-80A3 FORWARD ENGINE MOUNT BOLTS **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES The side, sway and thrust link bolts of the CF6-80A3 front engine mount have a time limitation from their installation, calculated with the fatigue lives of the bolts and the yearly fleet leader data. They must be replaced at the next engine removal. Replacement is then repeated at the interval of 11 years and 2 months. This Service Bulletin details the replacement plan for all side, sway and thrust link bolts of the CF6-80A3 front engine mount. New bolts will have to be marked by one or two or three cross(es) depending on the number of replacement already done, to differentiate them from the old ones. Accomplishment of this Service Bulletin will replace the FWD engine mounts bolts (side, sway and thrust link bolts) before they reach their life limit.
