The FAA can reissue an airworthiness certificate. The place you get into trouble is if you can't get a signed FAA 8050-2 bill of sale for the plane. Some people cancel the registration and won't give the bill of sale because they don't want the liability and they sell the plane as parts. If that happens you can only register it as Experimental Exibition and Racing which has a lot of limitations. To re-register it as experimental amateur built you have to have the signed 8050 to prove that it was amateur built.
Of course there are people that take the N number off of a flying plane that they could not get the 8050 for and they dummy up records showing it as an unfinished and never registered or flying project that they bought. That of course comes with the risk of getting caught and lots of bad things happening if you do so I would not recommend it. Brian Kraut EA Manufacturing, LLC -------- Original Message -------- Subject: KR> Airworthiness Certificate cancelled or surrendered From: Mark Langford via KRnet <krnet at list.krnet.org> List-Post: krnet@list.krnet.org Date: Mon, October 31, 2016 3:46 am To: KRnet <krnet at list.krnet.org> Cc: Mark Langford <ml at n56ml.com> I recently saw a KR for sale that was "almost ready to fly". After looking at it I looked up the tail number and the plane has been "deregistered", as well as the Airworthiness Certificate. I've always thought that a deregistered aircraft was "dead in the water" but according to something I found on the web, there is apparently a path back IF the Airworthiness Certificate hasn't been "surrendered". I needed clarification on this, and others may need it also. I'm too lazy to look up the official regulation on this, but I'm sure it's not too hard to find. From a thread on Vans Aircraft: "Has the original airworthiness been surrendered? If so, the aircraft is "dead in the water". Once the airworthiness certificate for an experimental amateur-built aircraft has been surrendered, there is no path back. If the airworthiness is still valid, then no problem. It can be put back into service by going through a new phase I test program. No one but the original builder is eligible for the repairman certificate."
