AFAIK you won't be able to do an online search for 337s that I am aware of,
but for $10 fee, the FAA will send you a CD of all paper work on file on
that N number. The link is on the FAA web site.

I'm not sure if that will include uncleared liens, it is best to go through
AOPA or some other title search service for the liens.

Two items to sell a plane, Transfer or Registration and Transfer of
Ownership

I am looking for the FAA link to do a search of 337s on a plane and also
the place to do a search of leans on the plane (AOPA??). One last thing,
what paperwork is required now days to sell a plane.
