Official trials were conducted from August 1939, and the prototype was in process of being re-engined with an 800 hp version of the Gnome-Rhone 14M when the Wehrmacht approached Paris. The aircraft was dismantled and trucked to Bordeaux, but was subsequently destroyed when the building in which it was stored caught fire.
