Welcome To EAA Chapter 640

The membership of our chapter is made up of a great variety of pilots and non-pilots whose experience and interests range from aircraft of the 1930s through homebuilts and ultralights to aircraft of the present day. These are people who can share their experience and offer advice to those willing to ask. EAA Chapter 640 is a place to:

• Promote and encourage the sport and hobby of recreational aviation through the camaraderie of building, restoring, flying and learning.
• Foster closer fellowship among its members through the exchange of ideas and mutual interests.
• Promote and encourage aviation safety in the design, construction and operation of all types of aircraft.
• Foster, promote and engage in aviation education.
• Operate as a local chapter of the Experimental Aircraft Association, Inc. (EAA) and to cooperate with the EAA to further the goals and purposes of that Association.
