I watch a documentary on the investigation of this tragic accident.

Apparently the Tail was torn off at the connectors that fasten it to the fusealage. This was obvious as when the tail was recovers, you could see the fastners at the bottom of the tail. It was clear theyt had failed.

The investigation found that the Co-Pilot who was the PF at the time used more rudder in attempting to correct a yaw than he should of had. Although he was following the training given to him by AA.

This had sparked of a row between Airbus and AA, each blaming the other.
