I think the BEA report makes it entirely clear that there was nothing "wrong" with the airplane. This statement is in the broadest sense, yes the airplane had significant fault warnings however the plane responded correctly to all system inputs and the AP " kicked out" leaving the plane in a reasonably stable configuration.
At the time of the AP disconnect the airframe did not need to be "recovered" just flown. The upset was entirely pilot induced and not influenced by any erroneous instrument displays. The PF was simply overwhelmed and either forgot his training or never had appropriate training to begin with.
In spite of knowing that the PF was responding to the crisis inappropriately and immediately taking command he allowed the PF to continue a course of action that led to a potentially unrecoverable situation. To me the apparent company culture as it relates to CRM is the root cause of this accident. The least qualified pilot happened to be the designated PF and was somehow to allowed to continue flying the airplane in circumstances clearly beyong his ability to handle.
The PM should have assumed control within 15 seconds of AP disconnect based on the PF's failure to apply basic airmanship and fly "pitch and power" stabilizing the airplane while the PM worked to sort out and prioritize the fault warnings.
This is a scathing indictment of AF's safety culture and CRM training. For a seasoned pilot to sit there and watch a colleague kill not only himself but the SOB they are responsible for is criminal....literally. This comment is not aimed at the poor pilot involved but at the airline itself. At this point they need to be slapped down hard...and hopefully will be.
