The Mauboussin M.112, M-12 or Mauboussin M.XII was originally called the Peyret-Mauboussin PM XII and was renamed when Mauboussin founded his own company in 1931, ending his partnership with Louis Peyret. [1] [2] [3] It was a French, single-engine, two-seat, low cantilever wing touring monoplane. [2] At least six were built. [1]
The low, cantilever wing of the M.112 was built in three parts, a tapered centre-section which was part of the fuselage and trapezoidal outer panels with elliptical tips. Its aspect ratio of 9.5 was high for the time. The outer panels carried mild dihedral and full-span, narrow-chord ailerons. The wings were completely wooden, with twin box spars and alder plywood skin. [2]
It was powered by an uncowled 30 kW (40 hp) Salmson 9Ad nine-cylinder radial engine with its fuel tanks in the wing centre-section. Behind it, beyond a firewall, the wooden fuselage had a rectangular section defined by four longerons, though the upper decking was curved. It was covered in plywood. The M.112 had a pair of tandem seats over the wing, with the pilot at the rear. These seats could be open or enclosed by a removable cover. The fuselage tapered to the rear where the tail surfaces, also ply-covered, were straight-tapered and round tipped. Both horizontal and vertical surfaces had quite high aspect ratios and the vertical tail was tall; the horizontal tail was mounted on top of the fuselage. Both rudder and elevators were aerodynamically unbalanced. [2]
The M.112 had conventional, fixed landing gear. Its mainwheels, fitted with brakes, were on cranked axles and drag struts, both hinged from the lower fuselage longerons. There were short, vertical Messier oleo struts from the outer axles to the forward wing spars in the centre-section, giving it a track of 2.2 m (7 ft 3 in). Its tailskid, which could be replaced with a wheel, castered and had twin small bungee shock absorbers. [2]
Built at the Zenith factory, [1] [4] the M.XII first flew in September 1931. [1] In August 1932, flown by André Nicolle and registered as a Mauboussin M.112, it competed in the Challenge International de Tourisme 1932 (English: 1932 International touring aircraft Competition), which involved both technical tests and a 7,200 km (4,500 mi) circuit around Europe. It came last, but with its very low-powered engine, was the only aircraft in its class. [5] [6] [7] It also appeared at the 1932 Paris Aero Salon. [4] The French civil aircraft register included six M.112s, used by aero clubs and individuals. [8]
Aircraft in the Mauboussin M.120 Corsaire series which followed were similar to the M.112 but heavier and with more powerful engines. [1]

General characteristics
Performance
The Mauboussin M.120 was a trainer and touring aircraft built in France in the 1930s and again in the years following World War II.
The Peyret-Mauboussin PM XI was a French high-wing touring aircraft of the early 1930s.
The Peyret-Mauboussin PM X, PM 4 or Mauboussin M.10 was a low power, single-seat, high wing cantilever monoplane. Only one was built but it set several records in the under 250 kg (550 lb) class both as a landplane and a floatplane.
The Potez 40 was a French three-engine, braced high-wing monoplane designed and built in response to a French government programme for colonial transport and policing aircraft duties.
The Caudron C.251 Et-2 was a French tandem seat, open cockpit biplane designed as an intermediate trainer and built in 1931. It did not go into production.
The Albessard Triavion, sometimes known as the Peyret-Albessard Triavion, was a three surface aircraft, combining a tandem wing and conventional tailplane.
The SFCA Taupin was a French tandem-wing aircraft, designed to provide a simple, stable and safe aircraft able to take-off and land in small spaces.
The Albert A-60 was a single engine, two seat, wooden sports monoplane designed and built in France in the early 1930s. Two were built and flown with three different engines.
The Dupuy D-40 was a French built, low powered monoplane designed for touring abroad. The only example was used for an uncompleted journey to Saigon.
The Régnier 12 was a 1930s Belgian touring aircraft offering variants with different engines and seating plans. Only one was built.
The Dewoitine D.480 was a French single engine side-by-side sports and training aircraft built in the early 1930s. Two were completed and flew with several different radial engines. One remained active through the 1950s.
The Kellner-Béchereau 23 was a French two seat cabin touring aircraft, built in 1932. Its wing was constructed in a novel way. Only one was completed.
The Potez 42 was designed and built in 1930 to meet a French government requirement for a small air ambulance capable of operating in the colonies. It did not reach production.
The Guillemin JG.10 or Blériot-Guillemin JG.10 was a French two seat touring aircraft, designed to be as simple and safe to fly and maintain as a car, with similar facilities, as well as provision for parachutes.
The Poite 3 was a one-off, all metal touring aircraft which seated two in tandem. It was built and flown in France in 1931.
The Peyret-Nessler Libellule (Dragonfly) was a French two-seat, low-powered parasol wing light aircraft built in 1927 to provide practical but economical flying. It was one of the first of these French avionettes.
The Guerchais-Henriot T-2 was a French low-power, two-seat cabin cantilever monoplane built in 1928. Only one was flown.
The Bourgois-Sénémaud AT was a parasol wing, two seat touring aircraft built in France in 1928. Three examples were completed.
The Muniz M-5 was the first of Antonio Guedez Muniz's aircraft designs to fly; soon afterwards he became the first Brazilian to design an aircraft which reached series production. The sole example of the M-5, built while he was a student in France by Caudron, was a low wing cabin tourer or military liaison aircraft.
The Albert A-10 was a four-seat French transport aircraft which could be rapidly converted into an air ambulance. Two or three examples were built between 1929 and 1932, using at least two different engines, but neither variant reached production.
