Let us presume for the moment that the A300-605R that American has in their fleet, is as bad as
Wino suggests.
OK, now considering that
American Airlines ordered 35 of 'em, and
American Airlines carefully evaluated the design, and its requirements for use in
their fleet, and had their training Captains sent to TLS to attend the manufacturers course, so that these same
American Airlines training Captains could come back and report on
any problems encountered,
and pass this information on to
American Airlines line crews, so that no untoward difficulties would occur...well you get the point, I'm sure.
The question remains,
why did not American Airlines find out about any special problems that the particular type had, and
if not, why not?
You will note many references to
American Airlines in the above, and it is there for a reason...
American Airlines sets a very poor standard for itself, which it consistantly fails to achieve, at least in the flight deck crew training department.
IE: not many bright bulbs in the lamp in Dallas.
Good grief, and these folks call themselves a 'large scheduled airline'...phooey.
