The subject Order deals with airworthiness certification, & starting with Part 146 it's about experimentals.... A friend from Europe is working on (what he hopes will become) a new kit airplane and he's stumbled across Part 147.d that addresses prototypes.  Anyone have an idea of what the certification of that airplane would be since 147.d only says what it can't be.  Typical governmental legalese... almost seems like you need to simply call it experimental, and keep it divorced from any implication that it's a prototype.  Any thoughts out there?
