The EAA decided in 1955 to develop a single-seat sport biplane as a service to its members. The prototype was built as a classroom project by students of St. Rita’s High School in Chicago. It flew for the first time in 1960. The plane is, in a sense, the predecessor to the Acro-Sport, the difference being that the A-1 Biplane is lighter and uses a smaller engine, an 85 hp Continental. Construction is the same. Plans are no longer marketed.
