Would you rule out that Rudder may have reversed its effect, if not wholly, then intermittently?
Well they were at least 250 kts too slow to get any sort of aeroelastic reversal and the sidelip/control deflections never got into the non-linear range let alone stall, and even stall is not the same as reversal, so I guess I would rule out rudder reversal.
The Rudder, at 17 degrees sweep from vertical, plus AoA, supplies just the sort of tangential bias from airflow from under the HS and even behind it, at this point? That the airflow past Rudder in this direction works opposite its intended force? Keeping in mind that the elevators, fully UP, do not shield this surface from under tailplane flow?
Frankly, I haven't a clue what you mean by these remarks!
The Directional system is also in a transiently Stalled wake, that of the HS/elevators?
Don't be daft - take a look at a side elevation of an A330 at say 35 deg AoA. The HS sits well behind the fin LE and even if the HS were stalled there is no way that its wake would impinge on more than the very bottom of the rudder. And we know that the HS was operating with no more than about 10 deg AoA so it wasn't stalled and the elevators remained effective, so there wasn't any HS wake anyway.
As for the directional system being in a transiently stalled wake of the elevators, that is even more ludicrous since the elevator hinge lies at the same longitudinal station as the rudder
TE at the fin root. No way that any elevator wake (even if it existed) could wash over the rudder.
Perhaps off the wall, but the corner of the Rudder that exhibited damage was in this very unusual flow, and in effect, played leading edge to V/S system, collecting its drag from beneath and behind the HS/elevators? As such, it would be in vulnerable and undesigned for airflow, perhaps in some sort of leading edge flutter that corrupted the structure as seen in early photos?
You don't give up do you? That rudder damage was collected when the aircraft struck the water tail first and the APU was thrown through the top of the fuselage striking the rudder root TE. There is, and never has been, any evidence to support your wild theory of rudder failure in flight
