ABOUT US

The Glasair Aircraft Owners Association is the one must-join association for Glasair, GlaStar, Sportsman 2+2, Merlin, and OMF Symphony builders, owners, pilots, and enthusiasts. If you’re currently building, flying—or dreaming of building and flying one—this is the place for you! We are not affiliated with Glasair Aviation, LLC., but we maintain a great working relationship. Our members can be found worldwide.
