What item 5 says is that all chartered club members must be AMA members. What is does not say, and is referenced later in the document, is that you must be a club member to fly at a club field. That is a club decision. The clubs I belong to insist that you be an AMA member to fly at the club field. Guest's who are not club members, but do have AMA memberships, may fly there. As you can see, it is possible that a club would allow non-AMA members to be guests. It is strictly up to the club.

In order to protect the members of the club and assure that people that fly have the proper insurance, for the sake of the members and the landlord, most clubs have a rule requiring AMA membership.

I hope I have made this clear. It's a subtle difference in words, but a huge difference in meaning.
