It is not acceptable for the cause of this accident be put down to Wake Turbulence. We all encounter it 2 or 3 times a year in varying degrees.
As mention in another thread, it would only take a small amount of movement in the Vertical Stabiliser before the yaw damper would come into play possibly exacerbating the movement and breaking the structure of the VS. The noise of the FD would confirm the vibration.

Assuming that the VS then came off it would no doubt take the hydraulics with it. Does the A300 have quick shut off valves in the flight control hydraulic lines? If not the aircraft would rapidly lose all flight controls and become unflyable.
Even with hydraulics it would have been nigh on impossible to control with climb power on and no VS.
I presume that with high side loads on the engines and pylons that they exceeded their design loads for normal operation and came away.
Surely by now all A300's should be fully checked to ensure that nothing similar is occurring in other aircraft.
