Of course, it has not been definitively established that there _was_ a FADEC failure related to this accident, only speculation as to the possibility AFAIK. See http://www.cw360.com for more information (search for "Chinook"). Therefore, it's premature to include this as an example. (I exclude this by using the term "no-kidding" in my full statement, which was: "...it looks like we may have a no-kidding, post-test, primary flight control software bug that led to a fatality. This breaks a pretty impressive string of successes by the industry, IMO."
