In Canada, there is a requirement for a maintenance program. I have done them for both my planes, and a few other friend's planes.
The exercise of creating the program, which pretty well must be custom per serial number plane, is good for sending you looking for the various maintenance requirements from all sources. In particular, ICA's from modifications installed on the aircraft, which are sometimes overlooked. Even some PMA parts and avionics may have specific maintenance requirements or limitations, which are not applicable to the original aircraft.
