Whether you fly, build, restore or simply enjoy airplanes and aviation, you are welcome to attend our events and join our Chapter.

Based in Wausau, Wisconsin, EAA Chapter 640 is an active and engaged group of pilots, aviation lovers, mechanics, RC flyers, educators, students and their families.

We are a group of aviation enthusiasts, aircraft builders, and pilots who get together with like minded people to share ideas, exchange information, encourage safety, serve the local aviation community and have a lot of fun doing so.

We hold regular monthly meetings as well as special events at the Learn, Build Fly Education Centers at the Wausau Downtown Airport. Looking to connect? Visit our Facebook page, sign up for our email newsletter, or send us an email.
