Design and development

Maurice Brochet had designed the MB.30 parasol light aircraft and the MB.40 cabin two-seater before World War Two. His first postwar design was the MB.50 Pipistrelle ("Bat") of 1947, which first flew that year. It is a single-seat open-cockpit ultra-light aircraft with a pylon-mounted high wing, wooden fuselage frame and fabric covering. The design was kept simple with the amateur-built market, using factory working drawings, in mind.

The first MB.50 was built in 1947 by Maurice Brochet and was powered by a Salmson 9ADb 45 h.p. radial engine. The subsequent Pipistrelles were all built by amateur constructors. In 1965, six were active, three powered by the Salmson, two by the Beaussier 4Bm O2 of 45 h.p. and one fitted with a Zlín Persy II. Maurice Brochet formed Constructions Aeronautiques Maurice Brochet and designed the MB.60 Barbastrelle tandem two-seat high-wing monoplane which first flew in June 1949.

Survivors

Pipistrelle F-PEBZ was still active in 2005. Another was held in the collection of Ailes Ancienne Toulouse, near Toulouse Blagnac International Airport, during 2006.
