I can't help feeling there is a bit of the Eastern 401 problem here. If they were dealing with all sorts of other warnings, was anyone looking at attitude, altimeter, R.O.D.? An additional factor; could the PF be inadvertently holding full nose-up control? Unlikely on a conventional aircraft, but could he have been so busy with the other problems that he didn't realise he was doing it? The call at ten thousand is unusual; surely someone would have reacted to that, unless it was a Pavlovian call in the confusion. I don't think we will be able to know much else until the full CVR is made available.
