But rest assured ATSB will find a cause for the accident even if it’s no true and correct
Correct me if I am wrong, but I believe the US NTSB are required to publish a Most Probable Cause of an accident if they are unable to prove the factual "real" cause.
If so, it would be a useful Rule for the ATSB to adopt. At least it gives a sound reason for operators to review where applicable, their training policies for that type, rather than be left to speculate and pretend it will never happen to them.
