Hi All,
As far as i know there is still no conclusion from the AAIB about the cause of
this one and only structural failure. It keeps buzzing in my mind. It is a fact
that there should be no slop in tail planes, that the bushes should be secure,
and that wing pins should be properly attached. Period.
But was it the cause off the accident? Speed 90 knots, no abnormal movements, 
then
suddenly very steep up and down movements, paper flying from the cabin. All
according the AAIB report. 
I received the following suggestion, which i think has not been communicated 
before:
The plane was rigged by three persons. What if one of the anti-trim tab
drive pins was not in but on the T-rod? Everything would look pretty much OK,
feel pretty much OK, until the pin would pass the T-rod, on which the anti tab
would become a  pro-tab. This would cause a violent movement, on which the 
pilots
correction would cause another and so on, until destruction. It would explain
the described up and down movements eh? Start shooting please!

Regards,

Jos Okhuijsen
