I'm a little disturbed by Boeing's AD.
As a purely precautionary document - three cheers (but does it add to anything more than last Autumn's FAA one ?).
However, it seems a little too intrusive into the inquiries being undertaken by the proper authorities.
However, most importantly, there is no indication in the Boeing inturruption as to how the unknown process managed to affect two separate systems so similarly in time and effect.
Too much seems to be being read into something which is too vague.
