The Luscombe 11A Sedan was introduced in 1946 as a four-place, all-metal high-wing lightplane designed to meet specifications provided by the Flying Farmers of America. Intended for use as a combined business and family aircraft for rural operators, the Model 11 marked Luscombe's entry into the medium-performance general aviation sector. The aircraft featured a strut-braced monoplane structure utilizing a high-lift NACA 4412 airfoil across a 165-square-foot wing to optimize load-carrying capabilities and performance.
Production of the 11A took place in the United States, primarily in the Dallas, Texas area. While originally manufactured by Luscombe Aircraft, production continued in limited numbers after Temco Aircraft Corporation purchased Luscombe in 1948. The production window for the tailwheel 11A spanned approximately 1946 to 1949, with a total of 198 airframes built. The prototype, designated X11, first flew on November 8, 1946, while the Model 11A Sedan received type certification on October 4, 1948.
Technically, the 11A was powered by a single 165 hp (123 kW) Continental E-165 air-cooled, horizontally-opposed six-cylinder piston engine. This powerplant, paired with a two-bladed Sensenich or Lewis fixed-pitch propeller, allowed the aircraft to reach a maximum speed of 145 mph and a cruise speed of 130 mph. The aircraft had a gross weight of 2,280 lb and could accommodate one pilot and three passengers, or alternatively, 600 lb of cargo. Other performance specifications included a service ceiling of 17,000 ft, a rate of climb of 900 ft/min, and a stall speed of 58 mph when utilizing flaps.
As a purely civil utility and touring aircraft, the 11A saw no military or wartime service. Its legacy is defined by its rarity and all-metal construction, which earned it the nickname "Cadillac of Classic Airplanes" among enthusiasts. While the original Luscombe Aircraft Corporation is defunct, the design saw a modern revival in the late 1990s and early 2000s as the Luscombe 185-11E, produced in Altus, Oklahoma, and certified on December 17, 2002. Regarding surviving original airframes, records indicate that 41 Luscombe 11A Sedans remained registered in the United States as of 2002.
