...the Thales probes had problems with the drainage of water resulting in a blocked pitot , many carriers had switched to Goodrich which resulted in better performance.
There was an airworthiness directive issued regarding this well before AF447... mandatory on A320's, optional on A330/340's (at the time, now mandatory).

http://ad.easa.europa.eu/blob/easa_p...f/PAD_14-139_1

This Air Asia A320 was only built 6 years ago so would be fitted with the appropriate pitot tubes... not saying icing of the pitot couldn't occur, but certainly less likely.

... the replacement pitot's were also Thales models however, not the Goodrich models used now on the A330/340.
