To quote LeadSled, "My "claims" are based on a study for AOPA/AU, conducted by a professional researcher, with the results peer reviewed by a rather well qualified chap in the NSW Public Service, who was head statistician (with two PhD in the subject, no less) of a major department.
The then Minister, John Anderson was so upset at the figures, because they were so at variance with his "official" advice, that he sent them off to NTSB/USA for review and confirmation or damnation, preferably the latter.
The NTSB report in reply, in short summary said: " Of course they are correct, they are just a list of accidents from publicly available sources, using ICAO definitions, assembled as a comparison of national air safety outcomes."
Could you provide copies of the AOPA/AU study + the NTSB report please.
Also, I didn't understand the relevance of your comment that "I was in Tamworth the day after the Metro went in on training, and that was even an aircraft certified to the "Commuter" amendments to FAr 23" - please explain...
