Columbia Aviation Association is located at the Aurora State, Oregon
Airport (UAO). CAA was founded in 1949 as a private
organization devoted to flying. After being located at the Portland
International Airport (PDX) for forty five years, members
completed the beautiful new Aurora clubhouse in 1996. Membership is by
invitation only and requirements include possession of a private pilots
certificate. Most of the club's 230 members have advanced ratings and are
aircraft owners who fly on a regular basis for business and pleasure.
