Boeing addressed the 737 problem by redesigning the yaw damper system and

A300 is a non-sequiter argument. The fact remains, the A300 has a design
flaw of some kind that needs to be fixed. If Airbus wants to try to sweep
it under the rug, they are just going to wind of killing more people. They
need to proactively investigate the design and determine what is wrong, the
come up with a real fix. Tapping on the tail doesn't cut it...

Can you give a reference that shows where the 'flaw' in the A300 design
is?

There are three principle factors in an in-flight structural failure.

1. The design requirements. These are laid down by aviation
authorities, not designers. If these are wrong or insufficient
then they need revising for all aircraft of that class.

2. The designers who must meet those requirements and convince the
aviation authority that design and testing shows that these
requirements are met.

3. Those who fly and operate the aircraft and must see that all
maintenance training and operation are within the design limits.

If there is a flaw in which category is it? Over the years there have
been crashes in which all of the above have been in error. You cannot
design, build and operate an aircraft which is proof against _all_
errors or mistakes whether accidental or deliberate.
