G'day Mate, I see that you've been overwhelmed by all the responses. Have a look in the proposed new regs, Part 66 and the MOS (Manual of Standards) Part 66. I think that'll answer your questions or at least steer you in the right direction. The Oz stuff is a copy of the Brit CAA CAP 715, all of which are available on line at their respective sites.
Have a good strong coffee before you try and read them.
