Perhaps time to draw breath and summarise?
From the PROPER reports so far:
Trainee F/O flying A/P B coupled ILS into AMS 18R. J/seat pax of unknown status. Typical short-changing on track miles at AMS by ATC possibly caught the pilots and cabin crew a bit on the hop and the approach had the hallmarks of being potentially unstable. At around 2000ft, somewhere around LOC intercept, RA1 malfunctioned and sent a 'RETARD' command to the A/throttle (?and a 'Too low gear' GWPS?). The A/T action appears to have gone un-noticed, as the throttles were presumably closed at this point anyway. The A/P flew a 'normal' ILS, but with idle power, the speed was reducing below normal. Again apparently un-noticed until below cloud when the stall warning triggered at Vref-40kts. A fumbled attempt at stall recovery, apparently leaving the A/T engaged, resulted in a failure to complete a recovery. The Training Captain is then thought to have applied full power but too late to prevent a disastrous impact.
I think that is about as accurate as we can be at this time. The CVR and FDR will give the clues as to what was going on in the cockpit.
