Unsafe Condition
CFM56-5C forward engine mount thrust links fitted with oversized bearings will not reach the updated link fatigue life limit of 15,500 Flight Cycles (FC) due to an increase in bore diameter. The consequent potential failure of the affected thrust link would reduce the forward engine mounts' structural integrity and could eventually lead to engine separation.

Required Actions
Inspect the link assembly to identify a possible oversized bearing repair and, if found, apply the associated corrective actions. Alternatively, perform repetitive detailed inspections of the forward engine mounts for cracking, damage (e.g., dents), and missing fasteners until the link assembly inspection is completed.
