Seems to me that Airbus is, if not criminally responsible, morally and
legally responsible.

Then Boeing would also be guilty because the NTSB, very early in the
investigation, found that Boeing planes were also liable to lose tailfin upon
misused of rudder during flight.

Also early on, it had been revealed that AA stood out amongst all other
airlines with regards to rudder usage while in flight (training issue). If
the rest of airlines told pilots not to use Rudder to such an extent, then AA
stands out.

Airbus insists it has sent warnings about misused of rudder while in flight.
The question is whether a maufacturer (Airbus , Boeing etc) needs to approve
an airline's training programme for a specific plane. If so, the Airbus could
be held responsible for not forcing AA to change training to avoid misused of
Rudder. But if Airbus did not need to approve AA's training programme, then
why should it be held responsible ?
