American Champion Aircraft (ACA) produces FAA certified light acrobatic and utility aircraft for pleasure, work, training, and true excitement. The long standing design has proven stable and comfortable for over 50 years. The aircraft are a stronger, better built, better handling aircraft because of generations of refinement. We assure that the planes are built right, and not under the pressure of corporate cost / profit / production projections. We have owned the type certificate to the Model 7 and Model 8 Champion Line (Champs, Challengers, Citabrias, Decathlons, Scouts, etc.) since 1988. We have been supplying parts from the very beginning. New aircraft manufacture began in 1990 and has continued to grow since. ACA's line of "Champs" is centered around the design change of metal spar wings, offering a more stable and sturdy platform than before. The line continues to be improved and modernized. The line of Aircraft is still 100% FAA certified, and is still the most versatile and affordable two seat tandem tail-dragger in its class.
