: "The AT-01 Diamant was an one-of-a-kind homebuilt aircraft constructed by André Terrade. The aircraft was built using parts and components of two Jodel/Wassmer D-120 (F-BHYD c/n 46) and D-120A (F-BNHK c/n 308) aircraft and is often considered as one of the first Jodel aircraft to feature a swept vertical tail and flaps. The Diamant was powered by a 90 hp Continental C90-12F engine and first registered as F-PYBV on September 26, 1977, it was still registered in 2014, although to its seventh owner."
