It's the 91.411 and 91.413 deal. Legally only the transponder check
(91.413) is required for VFR every 24 months.
But to use your encoder you also have to comply with part 43 appendix e
paragraph C, or anytime work has been done that could effect the mode c
output.

Thanks. I've talked to another shop, and have been told that they can come
to the airport for at least part of the check. They want to check the
transponder on the bench, then put it in the plane to check the system. I'm
trying to talk them into skipping the bench check, since it's a brand new
Garmin transponder. Unfortunately, the owner of the shop is the one I need
to talk to, and he's failed to return my call twice now.

How hard is it to get started as a repair station :-) (only half kidding)

Thanks,
Rusty
