Hi Mark,
If you check pages 14, 15 & 16 here (
http://www.modelaircraft.org/PDF-files/clubkit.pdf ) you will get information on AMA Chartered Club's Safety Coordinator. As far as the AMA Chartered Club Safety Officer position, that role in the AMA Chartered Clubs was discontinued when the Safety Coordinator position was created by the AMA.
