Lots of talk here about having a "clear title". I have owned 29 airplanes and have never seen a title. Ownership is transferred by AC Form 8050-2 Aircraft Bill Of Sale. Proof of ownership is the aircraft registration. Don't make this more difficult than it is. If you have an 8050-2 signed by the CURRENT REGISTERED OWNER in the FAA registration database and your information is filled in as the purchaser then you own the airplane. Send it in with the FAA Registration Form and you will receive a registration proving your ownership.
