No.
Recommendations: Operators should ensure that flight crews have proper knowledge and proficiency:
- To detect and to identify unreliable airspeed indication.
- To apply immediate and conservative actions for ensuring
short term safe flight control, in accordance with the
manufacturer procedures developed for the specific aircraft;
the use of memory items should be considered.
- To apply procedures for the safe continuation of a flight with
unreliable airspeed indication up to a safe landing.
I think you might conclude that the air data system might have been a cause. They also say that flight crews (any flight crew) needs to have proper knowledge and proficiency in circumstances where there are air data errors.
You cannot infer that the crew on AF447 were not knowledgable or proficient nor that the air data system cause the crash. You might tentatively conclude that one or both were contributory but nothing else.
