Like me, on to the next step in the dreaded paper work. The next step is the affidavit of ownership that needs to be Notarized, and the Form 8050-1, Certificate of Aircraft Registration. Keep the pink copy. Also make copies of anything you send in to the FAA. When I send in the Certificate of Aircraft Registration, it starts my county tax bill on the airplane. Even through its not an airplane until the FAA says it is . Just a collection of parts.
