I think you'd need to discuss it with your friendly neighborhood DAR.

Some of those projects I see, I have to wonder if they were built and flown without the benefit of such luxuries as airworthiness certificates or registration. I remember when I was Champ shopping a few years ago, I found a few that were well out of annual but were more recently flown. Sometimes the pilot was no more recently and thoroughly legal than the airplane. When you fly off a farm strip in ND, I guess you don't really worry too much about the FAA ramp checking you.

Of course I'm sure most were just never quite finished.
