As yet there have been no criminal or civil proceedings regarding AF447, and thus no attempt to distill the contents of the BEA report (which covers all the potential causes including the Thales AA pitot tubes) into a legal narrative. The BEA report into AF4590 was similarly exhaustive - it was the *legal actions and not the report* which isolated the titanium strip as the major causal factor.
Coincidentally, aside from a premature but arguably understandable engine fire drill action, the crew of AF4590 performed in a logical, consistent and understandable manner once the flight became abnormal, despite facing what was later determined to be an unsalvageable situation. The PF of AF447 was faced with a relatively minor systems failure and, for whatever reason, performed in a manner which was contrary not only to established procedure but also to basic airmanship (pulling up consistently and repeatedly in the face of AP disconnect followed by stall warning) and his colleagues failed to check his actions or communicate amongst themselves effectively.
This is why crew action is considered to be a more prominent factor in AF447 than it was with AF4590. That said, and repeating for clarification, the problems with the Thales AA pitot tubes are listed as a contributing factor to the accident in the BEA report.
