There is a problem. A small but positive attitude, yes, but don't forget that there was said to be a yawing moment, sufficient to fail the VS at impact, and in a leftward direction. The BEA make a great deal of there being no aerodynamic loading to cause the separation of the Vertical in flight, and I think their term was "Struck the water En Ligne de Vol", (direction of flight). This means to me no yaw whatsoever at impact. So it seems to me someone is letting the authority have it both ways.
The Stabilizer stayed with the a/c, "what a stout airframe". It rotated off at impact even though the tail was following the nose "En Ligne"? Did it rotate forward around the #1 Clevis?
Two things are missing, as I see it. Metallurgy/Composite autopsy. Passenger autopsies as to injuries. One cannot learn from less than forthcoming analysis.
