logic of IO-360 100hr injector inspection 93-02-05

Once again, its time for the 100 hr AD sign offs for my Mooney. I
still cannot come close to understanding the logic behind the injector
line AD on lycomings. My understanding is that some A&P at some point
accidently bent some of the lines and didn't understand that it would
effect the available pressure to the injector. Ok, sounds like maybe
there should be an AD after work is done on injector lines. But no.
The FAA says we must check every 100 hours to ensure an A&P hasn't
made this mistake! This is silly! Has this AD ever actually caught a
real problem??
