Err, I don't think you mean that.

I have not done much research on the matter but can not recall a
control surface failure or linkage to a control surface of the sort
that might be be uncovered during run up as leading to an in flight
failure. One can fly a GA airplane into extreme turbulence and have
structural damage, but that possibility would not be uncovered in a
run up either.

So yes, I did mean what I typed. If there are factual examples of in
flight failures of control linkages that might have been uncovered
during run up I'd be happy to learn of them.
