This question has been tagged "opinion based": Would it be much safer to have to have an airplane inspected twice a year?
I believe it is not opinion based and it could even lead to very interesting answers if someone can find the data to answer it.
It is "just" a matter of finding how the failure rate of aircrafts changes in relation to time from from last inspection. This data may be hard to find but I don't feel it's an opinion.
How can (if it should) be edited to fit?
Ps: I say very interesting because it is entirely possible that failure rates of aircrafts post-inspection is a bathtub curve thus leading to the conclusion that inspections done at some (obviously extreme) rate is more dangerous than less inspection.
