The Wassmer WA-80 Piranha is a French two-seat low-wing cabin monoplane trainer designed and built by Société Wassmer. Based on the same construction as the company's WA-50 four-seater, the WA-80 was a scaled down version. The prototype, registered F-WVKR, first flew in November 1975 powered by a 100 hp Rolls-Royce Continental O-200 engine. Wassmer appointed a receiver and suspended production in 1977 after 25 had been built.
