FAA Proposes Update to Airworthiness Directive for General Electric CF34 Series Turbofan Engines

The Federal Aviation Administration (FAA) is proposing to update an existing airworthiness directive (AD) for General Electric Company (GE) CF34-1A, -3A, -3A1, -3A2, -3B, and -3B1 turbofan engines to require a one-time inspection and replacement of certain fan disks, as well as adding additional part numbers and serial numbers to the affected fan disks, in order to prevent rupture of the fan disk due to cracks that initiate at an electrical arc-out, which could result in an uncontained failure of the engine.
