Hi;
I am new in this forum and this will be my first message here.
I see that you dont search for a specific landing gear component maintenance manual. But if you would like to perform any action on components which are installed to aircraft, you should get approval to do that from many agencies such as FAA, EASA, etc. If you would get the approval, you can issue only their forms such as 8130-3 FAA, Form One EASA, etc.
The only way to learn is to work for one of component maintenance centers as interim or roster engineer. beleive me, you will not be educated by looking in CMMs. It is up to you anyway.
CMMs are only released by manufacturers. For instance, Boeing is producting their own landing gears and they have the CMMs which can be revised in advance.There is only one way to get CMMs for landing gears. This is what you should be owner of component.
