Welcome to the "509"
Hello and welcome to the EAA chapter 509 web page. Also known as Tri-County Sport Aviation, we serve Eau Claire, Dunn and Chippewa counties (and perhaps a bit more) in West-Central Wisconsin. We are a local chapter of the Experimental Aircraft Association. Feel free to log in or create a new account if you would like to use some of the interactive features of this website, like polls, forums and comments.
The chapter clubhouse is located at the Chippewa Valley Regional Airport (KEAU), where meetings are held on the second Thursday of every month starting at 7:00 PM. If you are interested in building an airplane or flying in general, we encourage you to attend. Use the map below to find us (click "Read more").
