It appears that the underlying certification basis for aircraft safety in the event of a intermediate power turbine rotor bursts is not supported by the rotor failure seen on QF 32.

So far as we know flight AF 447 fell out of the sky with its systems performing as their designers had specified, if not how they expected, right up-to the point that it impacted the surface of the ocean.

So how is it possible that incorrect air data could simultaneously cause upsets in aircraft functions as disparate as engine thrust management, flight law protection and traffic avoidance?
