The Hatz Biplane Association is a non-profit corporation whose purpose is to educate the general public about the history, development, construction, flying, and perpetuity of biplane aircraft in general and the Hatz and Kelly-D biplanes in particular. The Association issues serialized Hatz CB-1 and Kelly-D plan sets and provides a forum for builder support through a quarterly newsletter and Internet website.

Memberships in the Hatz Biplane Association are currently only $20.00 per year, one of the last great deals around. Along with a membership you will receive the newsletter and a complete roster of all Hatz Nutz so you may contact builders in your area. There are tons of back issues available, chock full of technical, educational, and fun stuff. Yearly membership runs through June.
