. Only two prototypes were built and the type did not enter production.
Design and development
The Bernard 82 was developed from the long-range Bernard 80 GR, which had been designed to set long-distance-flight records. The all-metal Bernard 82 was a three-seat long-range bomber, known at the time as a ''bombardier de représailles'' or reprisal bomber. The cantilever mid-wing monoplane was powered by anHispano-Suiza 12Ybrs
The Hispano-Suiza 12Y was an aircraft engine produced by Hispano-Suiza for the French Air Force before the Second World War. The 12Y became the primary French 1,000 hp (750 kW) class engine and was used in a number of famous aircraft ...

on 11 December 1933, and in March 1932 was joined by the second prototype. Flight testing showed the twin lateral radiators to be inadequate; they were replaced by front-mounted radiators. Landing-gear deficiencies were the most persistent difficulty encountered during testing. The retractable landing gear regularly failed; resulting in wheels-up landings. The problem was never resolved, and testing was halted in mid-1935; the production contract for ten aircraft was cancelled.
In August 1936 the second prototype was re-engined with a CLM Lille 6As, a licence-built Jumo 205 diesel engine. The diesel-powered aircraft, redesignated Bernard 86, was entered into the 1936 Paris-Saigon-Paris air race. The race was run in September, but the Bernard was not ready by then, so it was not used. There were no further flight tests; the units were scrapped.
