Folks,
In the mid-1990s the CASA CEO/Director of Aviation Safety was Leroy Keith, ex-FAA and a highly competent bureaucrat.
Similar to previous posts, Leroy continually told his troops that "A compliant organisation is not necessarily safe, a non-compliant organisation is not necessarily unsafe".
This, and Leroy's general approach to fostering aviation was absolute anathema to what we now call "the iron ring" at CASA, and said group conspired against him, successfully, to force his resignation.
If Leroy has remained, the rules re-write would have been completed in the original time frame --- 3 years.
Instead, all we achieved was Parts 21 to 35, over huge internal resistance and guerilla warfare within CASA.
Tootle pip!!
