AP is reporting a memo from AF to pilots saying the airline is replacing pitot tubes on all medium- and long-haul AirBus aircraft with newer models within the next few weeks:
AIRWORTHINESS DIRECTIVE

Airbus Industrie A330 Series Aeroplanes
AD/A330/1 Pitot Probes 12/2002


Background: The French Direction Générale de l’Aviation Civile has advised that operators have reported loss or fluctuation of airspeed when flying through extreme meteorological conditions. Further to an investigation, the presence of ice crystals and/or water exceeding the current limits of the initial specification of Rosemount pitot probes P/N 0851GR is considered the most probable cause of these airspeed discrepancies.

This Directive requires the installation of pitot probes meeting more stringent
qualification requirements.
