The Decathlon entered production at Champion in 1972, immediately before the company was acquired by Bellanca Aircraft Corporation, so only a handful were produced by Champion. Bellanca continued production of the Decathlon throughout the 1970s, moving to the Super Decathlon variant during 1976. Bellanca built over 600 of the 8KCAB design before production of the aircraft was interrupted when the company's assets were liquidated in 1981.
The Decathlon design passed through the hands of a number of companies through the 1980s, including a Champion Aircraft Company which was no relation to the Champion Aircraft of the 1960s, but no Decathlons were built in that period. American Champion Aircraft Corporation acquired the Decathlon design, along with the 8GCBC Scout and the group of Citabria and Champ variants, in 1990, bringing the Super Decathlon version back into production that same year. It is still being produced.
