@Winnerhofer:
Your link is to the front page of the blog rather than the specific post. I think this is what you're after:
AF 447 : avant le non-lieu : Les dossiers noirs du transport aérien
M. Marnet-Cornus does not specify where this information is coming from as far as I can see. And while I agree with his point that the role played by the apparent slowness in replacing the AA pitot tubes should not be ignored, I can also see why making a strong case against Airbus would be difficult in that regard. Because while the manner of their mandate to replace the pitot tubes left the specifics regarding timing up to the airlines concerned, the fact remains that
they did mandate the change and provided materials to the airlines which constituted a workaround for the problem in the interim.
However, this still potentially leaves AF open to answer questions, as it was their timeline for applying the Service Bulletin that meant that particular aircraft did not have the fix applied when it encountered the conditions which blocked the pitot tubes and ultimately crashed.
