I don't have the answer to your question, but I'm sure that's a rathole that the EAA doesn't want to go down. The aircraft could be anything from a simple C152 to a Citation or Gulfstream. The most common damage I've seen is from a ramp person damaging a wheel pant becuase they don't use the proper towbar or know how to tow that particular model of aircraft. My personal opnion is that I would only have the owner/operator move their aircraft to minimize the risk exposure. I suspect that the EAA will have a similiar opinion. That is why they require a minimal insurance level from each pilot flying an aircraft before their umbrella policy kicks in. I will be pleasantly surprized if that is something the umbrella policy covers.
