I'm open to all ideas here. I just didn't have any reason to dismiss the statement I received from the FAA
(made nearly a year after that letter was sent). It's quite odd that FAA employees responding to
[email protected] would make such bold statements if they weren't certain they were true.
Can you share the actual email response that you received? Perhaps you should contact them again and ask them, specifically, about that letter.
So, it's your opinion (correct me if I'm wrong) that the FAA is allowed to interpret that vague statement in any way they choose. And since there is only one scanned document floating around on the Internet (that we know of) where the FAA mentioned the AMA (and there are no mentions of other organizations anywhere), all hobbyists must follow the AMA Safety Code.
The FAA gets to implement law, and specifically the Codes of Federal Regulations that they are responsible for implementing. That's simple fact, not opinion. Your previous example of registration is an example of that, and it wasn't overturned because they are not allowed to interpret CFR 14, it was overturned because their interpretation was found to be in conflict with Public Law 112–95 Section 336.
Aside from that, are you trying to argue that the AMA is not a nationally-based community organization for model aircraft, or that it does not have a set of safety guidelines? Because that is what the law requires and so it is not very surprising that the FAA used them as an example in that letter.
And you still appear to be attempting mental gymnastics in an attempt to discredit the letter. It's not some random letter "floating around on the internet"; it is published on the AMA website and, no doubt, accessible from the FAA via an FOI request. I get the impression that you are quite determined to defend a very weak position here, and I cannot figure out why.
As for my opinion, nowhwere have I said that all hobbyists must follow the AMA safety code. I've argued that if they do follow that code then they are defensibly meeting the requirements of Part 101, especially since the AMA has the written endorsement of the FAA in that role. But if there is another approach that arguable meets 101.41b (that "
The aircraft is operated in accordance with a community-based set of safety guidelines and within the programming of a nationwide community-based organization") then that should be fine too. I would probably not go with the Boy Scouts of America though.
