主旨摘要

This AD requires removing from service, nine stage 3 low-pressure turbine (LPT) disks, identified by serial number (S/N). This AD results from the discovery of a material nonconformity requiring removal of the disk before the certified disk life of certain stage 3 LPT disks. We are issuing this AD to prevent uncontained failure of the stage 3 LPT disk and damage to the airplane.
