Welcome to EAA Chapter 105 and to our website! We’re in the process of updating the site, so you can expect new content soon.
EAA Chapter 105, which was incorporated in 1961, is located in the Portland, Oregon, area and is headquartered at Twin Oaks Airpark. We have more than 200 members, and can say with pride that we are one of the most active and passionate EAA chapters in the country. Our history is rich with aviation innovators and doers, and we continue with that tradition today. We invite you to come check us out, join our organization, visit us for our monthly pancake breakfast, and participate in the adventure and sheer joy of aviation!
