It is very easy to sit there like that idiot Bryon Bailey did and blame a crew.
Imagine a crew working their darnedest to save an aircraft that did its level best to kill everybody, and never knowing what the problem was, nor the system causing it, for the manufacturer and the regulator deemed it not necessary to tell them.
Previous crew encountered same problem and dealt with it safely. Th accident crew had the benefit of that experience (from the write up). They also battled the trim for 6 minutes clearly understanding they had a trim runaway. Why they didn't hit the CUTOUT and why after six minutes they could no longer successfully counteract it, is unknown.
Although I read an article that said they swapped to copilot control immediately preceding the dive.
