So you send the
337 to the FSDO for approval before installation, when the approval
comes back you install the transponder.

The seller is shipping the unit today, but (of course) we're coming up on
Xmas and New Years, and the avionics shop is in Illinois, so it'll
probably
be at least a week before I could get the installation done anyway.

How long does getting the 337 usually take?


While overhauling my engine I did a set of six 337s by talking
to the FSDO guy in advance and then brought the 337s over to
the office prior to the post-engine install test flight. In
other words, it didn't take any time.
