How do you go about getting it registered in the U.S.?

Assuming the aircraft is a US manufactured plane with a type certificate.

First the aircraft is "deregistered" by the governing authority of its
country of origin.

Next the US buyer presents evidence of this deregistration, a bill of sale,
and applies for a US registration.

Now the buyer contacts a Designated Airworthiness Representative, or his
local FSDO and arranges for a type certificate conformity inspection.

An annual inspection must be completed within 30 days of the conformity
inspection.


Sounds easy huh???

Looks like a weld on the engine mount no 337 huh---- Is that air box
original to the airplane?? I don't see any numbers--prove that it conforms
to the TC. What kind of a log entry is that for those ADs? it doesn't
conform to our regulations, do all the ADs over again
What is that sooper--dooper auto pilot doing on this aircraft??? field
approval or yank it out.

It can be painless or terribly painful I've seen both ways.

I've got one sitting behind my garage with the wings pulled. Registration
was completed, corrosion on the spar cap discovered during the inspection
process---The owner will perhaps part it out---

Another from Canada cost almost as much as the purchase price to certify.
The owner could have had a flying plane in half the time for half the money
by buying US.
