reading the FAA note, I'm not sure where the EAA thought it was just
"complex kit-built aircraft"... but I sure wouldn't want to
fill out a 8000-38 to get on the "approved kits" list today

the Lancair PropJet is currently on that list since 2002..

this list is very depended on what's on your bill of sale.

paperwork is how the government tracks how much the owner has done or bought.
