All this 'spin' about the First Officer not using the rudder in an inappropriate manner is so much AA APA nonsense.
When one places his size twelves on the rudder pedals and pushes hard (as the previous Captain indicated happened before), the results are not pretty, as all can clearly see now.
Strange that only AA have had these problems with the A300-600...and no wonder why.
Less than adequate flying abilities (and certainly poor uninformed training) at the pointy end...not good.
AA, to be avoided whenever possible.
