Cavitation on other Aircraft of this type?
That cavitation was present is interesting, but not dispositive, unless it is so unlikely to be found on other aircraft of this configuration that it almost certainly points to icing as a cause. Suppose the AAIB examined other RR 777s. What percent would be found to have cavitation of this pattern? If the answer is lots, the causal connection is less established. And as a factual matter, have they done this?
If this has been answered already, I apologize. Please refer me to the post # addressing my question.
