EAA, the Experimental Aircraft Association, is an international aviation membership association founded in 1953 and headquartered in Oshkosh, Wisconsin. More than 160,000 people currently belong to the EAA, with local Chapters in all 50 states and many countries.
Members are aviation enthusiasts of every age group, including many airline and commercial pilots, engineers, business people and even astronauts. They enjoy all types of airplanes, including "experimental" aircraft - those aircraft built by individual craftsmen, rather than in a factory. “Experimental” refers to the category of aircraft design by the Federal Aviation Administration (FAA) for these types of airplanes. Similar to standard category aircraft, Experimental aircraft are inspected and certified as airworthy by the FAA.
The EAA hosts one of the world's largest general aviation events, the annual EAA AirVenture Oshkosh Fly-In. This event draws more than 700,000 people and 10,000 aircraft to Oshkosh each summer for AirVenture.
