It
is known, and the answer is that yes it does happen on other types and with other pitot types on the buses. It probably isn't always reported, but when it is, the reports are there to find. Certification requirements might vary - in the sense that Airbus is known to require
wider range of operating environment testing than the regulations, and other mfrs may well do the same, but not exactly the same...
Could it be that this problem has more to do with the way they are installed than with the probes themselves (e.g. typical position on the fuselage)?
Could be, but there are many other variables to eliminate, and also the issue that on the same airframe, and same mount points, other pitot tubes have a much lower failure rate. Maybe, for whatever reason, the "bad" thales model tended to end up on 330s.
