It's become SOP with me. The mechanics "fix" something, then I fix
what
they unfixed. I expect it, I plan for it, I schedule for it, I do it.

I find it's easier to eliminate the middleman and just do the fixing
myself. Sure, I'm not as fast as the pros - but when you add in the
time spent fixing what they unfixed, it's probably a wash. It is ever
so nice when you finish the annual on your plane, and no new squawks
appear - everything is at least as good as it was when the plane went
in, and often better.
