I have thought the same thing for years.It should not be this hard...How do I find a list of ADs for my O-320E2A engine. It seems as important as this stuff is that after Googling for an hour I could discover the secret.

I have used this service before. It simplifies the research and organization of ADs. All sort of appliances that are attached to aircraft may have ADs; radios, mags, etc. I am not saying they are mandatory, but if you want to know about all ADs for your aircraft this is a nice tool. It is a subscription service.
