JR, Hoss, Abel, Jim, all you guys:
What this appears to me, on the face of it, is that the local BOD has ejected the guy from the AMA. If what has been described is true, AMA HQ has agreed.
Now, my AMA application asked nothing about handicap, or ability to even remain vertical whilst attempting to guide a model aircraft through the air by any of various methods. It also says somewhere in amongst all that stuff exchanged between my home and AMA HQ that if I am a member and abide by the Safety Code, I am insured. Period. If I give them my money and I get a card, I am a member.
The only way I know of to rescind that coverage is to make me not a member.
Now, if this local BOD rewrote their local safety rules (Which become part of the code) to reflect that 1) only "Solo Certified" members may fly solo, and 2) that members with defib/pacemakers implanted may not be "Solo Certified", then their Southerrn exposure is covered for liability. It is hanging waaaayyyyy out and exposed for a discrimination lawsuit.
