General Electric Company to Issue New Airworthiness Directive for CF6-45 and CF6-50 Turbofan Engines

The Federal Aviation Administration (FAA) proposes a new airworthiness directive (AD) to update the inspection requirements for General Electric Company (GE) CF6-45 and CF6-50 series turbofan engines with certain low-pressure turbine (LPT) rotor stage 3 disks installed, following GE's determination that the LPT rotor stage 3 disks' low-cycle fatigue (LCF) lives are below the current engine manual life limits.
