I think you badly know the BEA
They have no scruple for blaming everyone else than Airbus and the Airline, and this include the pilots.
In every accident since late 80's (habsheim, saint odile, toronto, cayenne, tahiti, concorde, 447, etc) the pilots were charged by the BEA (because they could not charge airbus nor Air France).
So in this case, even if we are facing a boeing and not an airbus, I think the pilots will be charged (but not air france who have changed the boeing procedure by inducing some unneccessary AT movements).
