While I applaud any action on the part of the AMA to improve the situation. I see this as an attempt by them to gain favor for their members in the eyes of the FAA. And in so doing producing a legislative leverage with which to coerce people into joining the AMA. Or to be forced to fly under those other rules.
Then what happens when another CBO forms? Will their members receive the same consideration? Automatically? Or will they have to jump through hoops first? And if not, why?
I see a Constitutional question here and a serious law suit. One I believe the AMA has no chance of winning. The AMA may need to consider what such an event might do to their organization before they push an AMA only rule. Not that they haven't been seeking such leverage from the very start.
