Aeronca ceased all production of light aircraft in 1951, and the Champ design was sold in 1954 to Champion Aircraft, who continued production of some of the more advanced variants of the Champ, from the 1950s into the early 1960s-gradually modifying them into the aerobatic Champion Citabria [REF].
Champion Aircraft was acquired in 1970 by Bellanca Aircraft which continued production of their Champ-derived Citabria and Decathlon designs.
