Maverick,
Your quote :- "If that happened and it took out the left hand side of the tail plane lift will still have been produced on the right hand side turning the a/c to the left"
Sorry Maverick, but the tailplane does not produce upward lift but download; the cg of all commercial aircraft being forward of the centre of lift. That being the case, it would have rolled t'other way.
Let's wait (im)patiently for the report shall we?
