Abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to General Electric Company (GE) CF6 series turbofan engines. This action requires a more detailed fluorescent penetrant inspection process for GE CF6 series high pressure compressor rotor (HPCR) stage 3-9 spools. This amendment is prompted by an uncontained failure of the HPCR stage 3-9 spool attributed to a material defect located in the hub to web transition area of the stage 6 disk. The actions specified in this AD are intended to prevent an uncontained HPCR engine failure, which can result in damage to the aircraft.
