everything you might wish to do to an airplane has now suddenly become
a major alteration no matter what, and every minor part, practically
right down to even the "decorative furnishings" in the cockpit must
now be PMA'ed, TSO'ed, STC'ed, or factory original parts only, and
getting any kind of field approval is a crap shoot.

I've heard of clamp-on Ram mounts for Garmin 196's being cited as
major mods. No, I'm not confusing it with the Air Gismo dock where a
hole is cut, but a mount clamped to a support.
