and perhaps get this FADEC hysteria into perspective.
WK, I think that you are the only one who is introducing hysteria into the subject of FADEC.
Generally, the likes of tucumseh refer to it as one of several examples which demonstrate that the Chinook Mk2 was not airworthy at the time. As far as I can see no-one is claiming more than a possibility that a FADEC failure could have had any influence on the accident.
The clear evidence that the aircraft was not airworthy should have eliminated those responsible for that sad state of affairs from any say in the outcome of the BOI, other than to give evidence as to why they allowed it to be used for this mission against the wishes of the crew.
It is interesting that we see little from JP, caz et al defending their masters on this issue.
