Summary
We are superseding airworthiness directive (AD) 2013-02-02 for certain CFM International, S.A. CFM56-3, CFM56-3B, and CFM56-3C turbofan engines. AD 2013-02-02 required removal from service of certain high-pressure turbine (HPT) disks manufactured by Global Material Solutions of Pratt & Whitney, at reduced maximum life limits. This AD corrects the serial numbers (S/Ns) listed in AD 2013-02-02. This AD was prompted by reports that certain HPT disk S/Ns in AD 2013- 02-02 and in certain Pratt & Whitney service information are incorrect. We are issuing this AD to prevent uncontained release of multiple turbine blades, damage to the engine, and damage to the airplane.
