You can easily install it and meet all the requirements. This
is a relatively simple job. There is lots of supporting data.

Your success will depend on whether this guy has any
standing with the FAA.

You can find out. Have him prepare the 337 and flight manual
ahead of time. Have him take it to the FAA avionics inspector.

If the feds will field approve it, you are golden.

Then the installation could begin and the money pump start.

I'm curious where the actual requirements are for installing an IFR
GPS. My local A&P says he knows an avionics guy who is semi-retired. I
wonder if I could install a 430 in my KX-170B hole and have him sign it
off. Would Garmin or any reseller sell me a 430 directly? For approach
approval would the avionics guy just need to sign off the demo flight,
what really is the reg for signing off an IFR GPS install?
