And, as Gary points out, having somebody explicitly experienced with the 150 or 152 is definitely an added bonus. Case in point. I had two different I/A's inspect 72G on successive annuals. With me looking behind them. Yet, the third, (and present), I/A immediately found the cracks in the bulkhead / doubler where the leading edges of the tail feathers attach. There is no doubt that they were there all the time. It just took somebody that knew what to look for to recognize them. People ask me why I do not get my I/A and do my own inspections? Because even if I did have my I/A, I would still want that second set of eyes to inspect my airplane. No A/P, or I/A, is absolutely infallible. (though I am acquainted with a few that sure think they are!)
The last annual after Gary found a little corrosion where the pivot bolts go through the wing and wanted to put that nasty stuff in there. Scotch brite and a little primer took care of it. Now it appears my starter is crapping out. So stuff happens. You would think a top notch A/I would be able to predict things like that happening.
