Engineering (*especially in aviation*) is about making something as strong as necessary, but no stronger.

If there has not been "any problems" with it why is there a repetitive
eddy current inspection on Hartzell prop hubs. ????

Because companies who have reliable products don't sell enough
products. Toss in the fact that the FAA will issue an AD almost
anytime a company asks for it you have your answer.

Ya, I kinda thought about that just as I hit the send key. I have
owned a few certified planes and most of the AD's I had to comply with
made me just shake my head in disbelief. Thats why I have an
experimental homebuilt now. I NEVER want to see a yellow tag again
either. I have had a few "yellowtagged" components try to kill me....
