That is actually kind of scary.

How many cycles does the airframe have to go through in order for this to become a problem? I tend to think that if the FAA gave a shit about general aviation maybe we wouldn't be flying planes from the 1960s

For airliners, the airplanes are retired after a certain number of cycles. The 757 was designed for 62,000 flying hours, if I recall correctly. It's scrap after that.

My dad's B-17 in WW2 was scrapped after 30 missions, it was considered worn out.
