What I find absolutely fascinating is that someone who appears to be outside the certification or manufacturer's flight test business has done such a thorough job of analyzing some of the failure modes of the FADEC.
Not just well done, but three cheers for a superb job.
Why are these failures modes (which are probably common to the Bell 407 as they share many of the same components in the engine and FADEC) not more widely known???
(I can tell you from doing the certification flight testing on the Bell 407 that we didn't know many of them....)
