Memberships and Organizations

Experimental Aircraft Association (EAA)If you're interested in experimental aircraft or plan on building/owning one, membership is a must with this fantastic organization. Just the magazine "Sport Aviation" is worth the dues (~$40/year).
Central States Association (CSA)If you own or are building a Rutan aircraft (Long-EZ, Varieze, Variviggen, etc.) membership with this organization is an absolute must. The quarterly newsletter contains numerous articles, ideas and manadatory changes for the aircraft. A roster of members is published regularly and is a great source for finding other owners in your area.
Aircraft Owners & Pilots Association (AOPA)If you are a pilot or own an aircraft, membership with this organization is a must. The magazine alone is worth the dues (~$40/year) and they fight for general aviation rights.
