could be part-based on the FDR data; but it could equally - imho - be based on what is known about the flight from ATC data and communications, plus paperwork and witness statements about the prior difficulties that this particular a/c had recently encountered. So, previous flight crews could all have said that, having gone to manual flight following sensor disagree alerts, they then encountered strong and unexpected nose-down stab trim, uncommanded by them.

Interesting observation. If true, does that mean everything written on the accident is nothing more than pure speculation or informed discussion which in turn becomes perceived fact ?
