Awhile back I reserved an N Number and got the letter saying it's available but I can't use it until I send a written request describing the aircraft by manufacturer, model, and serial number. Since the plane isn't registered there is no such plane.
I'm filling out Form 8050-1 and there is a place for the N Number but technically I do not have one since I haven't formally requested it.
Can I just write my desired N Number on the 8050-1 form and attach the letter showing it has been reserved?
I'm probably over thinking this. Sure I've built my own airplane but have probably lost a lot of common sense over the last 4 years.
Thanks!
