Thanks for the replies, FITS/Marker. This is more or less what I assumed; but I still find it odd that the airlines who perceive themselves as being undercut by the shadier operators who work only at FAA minimums don't try to increase the burden on those competitors (by lobbying for shorter duty hours). But evidently, they don't, so what the hell do I know. (...blah blah blah game theory blah blah blah prisoner's dilemma blah blah blah...).
CC - To be fair, the review is supposed to be of training as well as fatigue, and the PIC's failure of several (4 or 5, from memory) reviews seems likely to be examined.
I know this probably sounds hopelessly naive, but there's no evidence right now that the new head of the FAA is doing this for anything but the right reasons...
