Information presented to the Captain on arrival consisted of problems with:
- Speed indication
- Lateral instability
- Pitch instability (to a lesser extent)
The Captain arrives at 02:11:42.5 - in many ways the worst possible time for diagnosis. At this point the stall has developed and the nose has begun to drop sharply - he was never aware that the aircraft had been held nose-high for over 30 seconds prior to his arrival.
As such he was mis-cued by the information presented and, as a methodical professional, tried to solve the problems he was aware of as they presented. He was missing a vital piece of information from the start of the sequence and had no reason to look at trim initially. By the time the PF makes his admission of pulling up for some time it's too late, and shortly thereafter the GPWS was taking all their attention.
