If you actually have a read of the accident investigation into the American Airlines crash you will find it was caused by the pilot flying using the rudder incorrectly during a wake turbulence encounter which resulted in it exceeding design load limits. This is a gotcha in any aircraft not just Airbuses. As for the Air France accident, information is unfortunately very thin as the Flight Data and Cockpit Voice recorders haven’t been located but the most likely cause was because of European made pitot tubes fitted at the time to Air France A330’s that had a know safety problem. All of Qantas’s A330’s as well as my own carrier’s have upgraded pitot tubes made by an American manufacturer that have a very good safety record.
The A330/340 has no more or less problems than any other airliner that has been in service for 15+ years.
