I'm happy to stand corrected, but if I recall it correctly the old DCA "P" chart data was actually derived from data "flown" by or under the supervsison of the DCA and paid for by the manufacturer and/or his local representative.
The manufacturers data was ignored, presumably on the basis that the air was different in the US,
but certainly on the premise that the information was for "sales" purposes and therefore not to be trusted.
This information and the copyright was "owned" by the manufacturer or whoever had paid for it and it was required to be included in the AFM for the new aircraft wjen it was put on the OZ register.
What that meant was if you tried to broker an aircraft into the country from other than the factory representative the only way you could get an Oz AFM was by buying a license for it from the copyright owner, the factory representative.
You could photocopy the info from another AFM to get it registered but that was a breach of copyright and therefore could not be accepted by the DCA therefore no rego, in any event the local DCA offices made it easy for you by giving the applicant a copy anyway.
But who cares about the niceties of copyright and the law, this is Oz aviation after all.
By the time this was becoming a problem it was all over in Oz piston aviation anyway, DCA was being dismembered in a way that made the Rape of Nanking look like a fairy tale and just about everthing worthwhile was being thrown out with the bathwater.
It would have made an interesting case with just about every Regional office inc HO, in court with their respective @rses being sued.
So now we come around in a circle once again, in any event what would the manufacturer of the aircraft know anyway.
