It's that attitude where i am pointing to, IMHO it's better to use all
brains available, feed all the facts and see where the discussion leads.
The change that the right solution is found is certainly not smaller. In a
way that is happening here. Excluding myself, there are some very
knowledgeable folks around here. The problem is that the facs are few and
secondhanded. And we all feel insecure.

Simply grounding every plane certainly makes the flying a lot safer, no
doubt about it. But it does not affect all Europas outside the UK. One
more reason for openess about what happened.
There are a lot of Europas flying around with sloppy tailplanes. Why did
this happen now and how and what evidence is there is what we would like
to hear. That will not impede the investigation, and maybe prevent
accidents outside the jurisdiction of the PFA.

Could it be that the moment the drive pins disengage the plane will
sharply dive or climb, resulting in the loose tailplane turning square?

Sure, but certainly less likely as close to VNE. The flags will flutter
quit a bit more too.

So,let'shave the facts. Conclusions may come later.
