An AD was put out to swap the tubes but that was prior to the crash.
Afterwards....no grounding happened despite multiple airlines reporting faulty airspeed indications on that plane.
So...no problem with that model? Yeah....ok.
Right....but how many of those A330/340's crashed? There were also known mitigation procedures promulgated for A330 crews at least to understand the possible presentation of an iced pitot probe on the planes avionics and how to deal with it.
