08/31/2010. Maurice Brochet of Neauphle-le-Château, near Paris, France, was an active member of the homebuilt aircraft movement. He built his first glider, the MB 10, in 1931, followed by several others, including Avia 20A and Avia 32E. In 1933-1934 he converted a wrecked Avia 15A glider into the MB 20 powered glider, while in 1934 the first powered monoplane appeared, the MB 30.
