From this thread, one is bound to consider that the investigation has as yet not produced enough evidence to fixate on any initial cause.
However one is bound to consider two scenario's as most relevent (again from stuff on here, not the official report)
1. Ice blockage of all pitot tubes rendering the aircraft impossible to fly.
2. Aircraft entered a weather situation where it was unable to maintain flight. Pilot or Pitot?
1. is of course a technical fault, however the concensus here seems that failure of the pitot tubes could only be as a result of the aircraft being in bad weather.
Although this thread brings up some fascinating and very relevent technical information, it seems pretty obvious that the aircraft crashed because, for whatever reason, a decision was made to enter a weather system that it was not capable of dealing with - it's got to be as simple as that
