I searched but didnt find any obvious thread that addressed this. I read 91.225 and im not sure its 100% clear. If i buy a 73 year old champ that has never had an electrical system, can i fly it within the mode c veil, or more specifically, under the bravo shelf after jan 1 2020? I think the answer is yes based on 91.225 (e). There are lots of references between sections that almost seem to be designed to be confusing.
