Max Holste MH.1521 Broussard

The Max Holste MH.1521 Broussard is a 1950s French six-seat utility monoplane designed by Max Holste to meet a French Army requirement.
Design and development.
The MH.1521 Broussard was designed to meet a requirement for a lightweight liaison and observation aircraft. It is a braced high-wing monoplane with twin vertical tail surfaces. It has a fixed tailwheel landing gear and is powered by a nose-mounted Pratt & Whitney R-985 radial piston engine. 
A smaller Salmson 8 As.04 powered prototype aircraft, the MH.152, was first flown on 12 June 1951; it had room for a pilot and four passengers but was too small and underpowered to meet the Army requirement. As a result, the company decided to develop a slightly larger version, the MH.1521 with the engine changed to a Pratt and Whitney Wasp Junior, which at provided almost twice as much power. The MH.1521 first flew on 17 November 1952. It was later named the Broussard (lit. Man of the Bush, in the context of bush pilots rather than Bushmen). Its development was enthusiastically supported at a political level by WWII fighter ace and French war hero Pierre Clostermann, a close friend of Max Holste. Clostermann wrote a faction novel, "Leo 25 Airborne", based on his experiences flying Broussards with Escadrille ELO 3/45 in Algeria.
The first production aircraft made its maiden flight on 16 June 1954, and 363 were built before production ended in 1961. Its similarity to the de Havilland Canada DHC-2 Beaver in looks, capability and performance led it to be nicknamed "the French Beaver".
Operational history.
It saw service in the Algerian War as an Army cooperation aircraft, mostly as an artillery spotter and in an air supply/ambulance role where its good short-field performance and resistance to ground fire were required. Its distinctive sound, made by its noisy radial engine and large propeller, was a disadvantage as the Algerian guerrillas could hear its approach long before other aircraft. It remained in service until the 1980s, and can still be seen in Denmark, France, the UK, and the United States being operated by enthusiasts or collectors.
