When an A&P/IA signs something off it just means it was functioning within

For that matter, I can't recall any time that an A&P or IA signed off on my avionics.
It's not part of what they check for an annual inspection. The only time anyone has
signed off one of my units was when I took it to an avionics shop for repair or for
some required tests, and that person is not an A&P.

This marriage is off to a shaky start. The groom just asked the band to
play "Your cheatin' heart", and the bride just requested "Don't come home
a'drinkin' with lovin' on your mind".
