On the French speaking web site, they have published the details of an incident which occurred "a few months before" AF447. In that case, maintenance have found that the three probes had the water drainage holes blocked. My question is again a naive one: in such a case, the problem is considered to be solved once the drains are cleared and the pipes flushed (as per the Airbus procedure), OR is there a mechanism to at least trigger more frequent inspections? For sure if maintenance is done correctly, then it should NOT be normal to find all 3 probes with the drains blocked?
