Wino,
We'll see, when the final NTSB report is released.
Have to ask tho, why is it that only AA have had this problem with the -600R AirBus models.
For example, have friends at SV, and they report absolutely no problems whatsoever.
And they have operated these aircraft for over 17 years.
If it ain't the aircraft, it has to be a rogue pilot induced problem, in my view.
Either that, or improper instruction from the training department.
This is not to say that AirBus aircraft are not just a little bit 'strange' regarding systems design.
