the real issue here in my view was that the aircraft should never have had the ability to do this in flight and when it was first brought to light it should have been fixed
Hear Hear.
It makes you wonder about the original Type Certification, and then the subsequent reluctance of the OEM to address the situation when it became apparent. It took several years before the National Authority mandated a fix, which became available in the form of a Service Bulletin. The FAA required it much earlier, and with hindsight the other jurisdictions
should have followed suit in the name of
Safety.
