Full official abstract

We are adopting a new airworthiness directive (AD) for the products listed above. This AD was prompted by a report of an uncontained failure of a first stage turbine disk that had a metallurgical defect. This AD requires inspecting certain serial number (S/N) first stage turbine disks, part number (P/N) 3101520-1 and P/N 3107079-1. We are issuing this AD to prevent uncontained failure of the first stage turbine disk and damage to the airplane.
