I just can't see how a rudder trim runaway, or rudder hardover could cause it to fall off! The aircraft had just got airborne, therefore I doubt the airspeed could have been high enough for this to happen. If it was in the criuse then maybe....
The CVR tape did not indicate that the crew thought that they had an engine failure. It talks of "Wake" and "Losing control" but no engine failure/fire call!! Perhaps this has just not been released yet. There was also no talk of any Warning noises on the flight deck. ECAM or whatever they have. I think it is strange that this has been ommited from the tape, and that no comment was made as to the nature of the problem. The only call seems to be, as I said, of losing control.
However it was just a preliminary report of the tape. I am sure we will find out more in the coming days.
Also, as someone else mentioned,the aircraft would not have sufficient pressure to blow the tail off!
This just gets stranger as the days go on!!
