Apparently, FAA inspectors don't have to hold a medical to issue a type rating but that's FAA. Not sure about what the FAA calls Aircrew Program Designee (APD) for a Part 121 operator. Found this but it doesn't answer your question. The link at the end of this page contains an email address for asking such questions...maybe it'd help. Do you have the legal ability to live/work in the USA ?
