Dann poste ich es auch mal hier
Auf aero.de kann man es auch lesen, aber im Original ist es einfach professioneller
Um es kurz zu machen, nachdem der Fan Mid Shaft mehrfach bei Tests bzw Take off roll gebrochen ist, und das alles bei etwas gleicher Stundenzahl... gibts nun die Anweisung an die FAA, eine AD ins Leben zu rufen, um ALLE Engines before further flight untersuchen zu lassen. Auch ein mehrfacher Engine-Fail wird nicht ausgeschlossen
Because of the short time to failure and the fact that all of the engines on any single airplane, whether the 787 or the 747-8, have all operated for the same period of time, the NTSB is not only concerned about the potential for further fractures occurring, but also the possibility that multiple engines on the same airplane could experience an FMS failure.
Issue an airworthiness directive to require, before further flight, the ultrasonic inspection of the fan midshaft in all General Electric GEnx-1B and -2B engines that have not yet undergone inspection. (A-12-52) Urgent
Require operators to accomplish repetitive inspections of the fan midshaft (FMS) in all (on-wing and spare) General Electric GEnx-1B and -2B engines at a sufficiently short interval that would permit multiple inspections and the detection of a crack before it could reach critical length and the FMS fractures. (A-12-53) Urgent
