There are test requirements for a reason. The time to change the testing requirements is before you do the tests, not as a way to cover up the shortcomings of a new airplane design.

The National Transportation Safety Board determines that the probable cause of this accident was the in-flight separation of the vertical stabilizer as a result of the loads beyond ultimate design that were created by the first officer’s unnecessary and excessive rudder pedal inputs. Contributing to these rudder pedal inputs were characteristics of the Airbus A300-600 rudder system design and elements of the American Airlines Advanced Aircraft Maneuvering Program. "
That crash was not the result of the training device used to train the pilot, it was more to do with the program that trained the pilot. Indeed, I don't want rookie pilots in the sky deliberately flying into wake vortex just so s/he can figure out how to evade problems.
If the Feds are willing to accept a computer model then that really is the final word. I doubt Airbus are in a position to strongarm the FAA into accepting it.
