Here is the situation. I am looking at a really good deal on an 2-seat "ultralight" that never got an airworthiness or registration. It has no build logs and no way of ever getting registered as-is. However, it is built almost entirely from bolting tubes together (almost no riviting). Would it be reasonable to buy the aircraft, break it down into its original kit form, and then rebuild it with logs? Will this create any problems with a DAR?
