That looks to me like giving advice to clubs on how not to violate the law. FREE legal advice, mind you. Or legal advice we've paid for with dues but given without us needing to ask. However you prefer to spin it, it's helpful and thoughtful. I see nothing there about clubs checking registration. But in that tiny chance of someone from the FAA showing up wanting to check it or the ever so slightly larger chance of an accident happening and that number being asked for, this lets the pilots be assured they are in compliance with the law. Would anyone rather have the AMA not explain this to us?
