--- so, whats the requirements to fly over here on a FAA ticket? and register my aircraft with a N number?
Ultralights,
Re. an FAA Class 3 medical, and a PPL ( or up, and not issued as a validation of a foreign license), it is reasonably straight forward, but there will be cost involved, get onto the FAA web site.
There is no CASA restriction on the private operation of an N registered Part 23 and up aircraft, but you will have to make arrangements for the US title to be held in US, and make arrangements for the annual inspection --- that is a very short summary ---- but it is possible, practical is another thing. If it is a Business Jet, too easy, a C-172??
Perhaps consider getting the full FAA PPL (or up, not a validation) then having it validated by CASA to fly VH- aircraft. There are a few other wrinkles (two year BFR) but it is possible.
Tootle pip!!
