In an effort to get my N-number before completing the RV12 I asked Van's for a Bill of Sale after paying for my finish kit. They gave me one 8050-2. I have completed 8050-1 which the FAA says is all you need "unless" you are registering an experimental in which case you need 8050-88a as well. And if its light sport then it must be completed by the manufacturer (doesn't say Builder like the EAB one.) The first thing the form asks for in the N-number as well as engine serial numbers etc. If this is another form Van's will be sending us along with the Compliance Form that is fine but all I want is an N-number so I can schedule a DAR when the time comes. Can anyone shed some light on this?
