I am just curious how much time Airbus marketing has spent before they came out with this.
As for EASA (and FAA consequently) it would be interesting what change is Airbus proposing in order to justify this.
Catch is that usually local CAA allows some test flights based on limit loads only and then the rest of the stuff based on the ultimate loads (1.5 x limit loads).
If you go to break the wing that means all the other test went smoothly. No it is unclear if they have finished ultimate loads tests or no. Also there is no word for what loadcase did the structure failed.
Still this is embarrassing and the only thing they could say is that "FEM was correct". Too bad.
Stating they will "use calibration of FEM" is, ahm, questionable. One can always do this with bad results so...
As someone said once in the end Airbus=EASA, Boeing=FAA and thus the way things will resolve themselves.
