I'd suggest pulling the CBs did not cause the problem but was a reaction to it.
I think it is obvious that nobody gets up and pulls the FAC CBs unless they have a problem. And it has been said earlier in the thread that there were log entries indicating issues with the FACs.
But a problem with the FACs does not mean that said problem caused a loss of control. Look at Adam Air 574 -- the pilots became engaged with a problem with the IRS and that distracted them from a much larger issue that caused their crash.
Perhaps focus on the FACs reduced the attention they were paying to other parameters.
