Good advice.If you want to fly PT 103, you better de register it and turn in the airworthiness certificate. Forever after don’t mention it ever had an N number. Remove evidence of it from the plane. Essentially it needs to be a different entity. How you deal with it being overweight is up to you as long as you don’t talk about it. How or what is ok, but once you lock in, follow the story. You don’t want to be caught flying without a license or a de registered airplane; you don’t want a tale of how you did it. Overweight UL is rarely investigated. If you did, someone had it out for you and knew the story. At that point it better be 254 lbs.
