The actual cause of AF447 was the inability of the flight crew to recognize a stall caused by iced up pitot tubes giving a unreliable airspeed indication. Between 2008-9 there were 9 incidents on ASR’s of temp loss of airspeed indications on AF 330/340 fleets. After the crash there were 6 more instances that weren’t on ASR’s. 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.
