Here I am studying for my Inspection Authorization (IA) written test which I am going to take on Friday. It is sometimes mind-numbing work. The regulatory aspects of it are confusing (let's hear it for the governmental bureaucracy!) There are so many regulations that it is difficult to get a straight answer from the FARs. You have to go through a lot of stuff. I have a good study guide, but unlike all the other FAA exams, the IA exam does not have a published question list.
