NWA A-330 Air Data System Problems

News story here.

The equipment failures, all involving Northwest Airlines Airbus A330s, were brief and were noticed only after safety officials began investigating the Air France crash — on a Rio de Janeiro to Paris flight — and two other recent in-flight malfunctions. The failures were described by people familiar with the investigation who spoke only on condition of anonymity because they were not authorized to comment publicly.

I do not recall many problems on the 319/320's in all the years I worked on them.

Did they change the system in the 330?
