10/31/2011. Remarks by Walter van Tilborg: "The four-seat Model 46 Coach was an original design of Jean Lignel and it became the last aircraft design built by SFCA-Lignel (Société Française de Constructions Aéronautiques-Lignel). The first aircraft of the type was first flown on August 13, 1947 and it was successful in several European rallies, held during the early-1950s.
The Model 46 featured a fuselage which was built following the so called Brodeau monocoque construction (no true internal construction and stiffeners integrated in the fuselage skin). Two examples were built, but further development was halted, partly due to problems with the 190 hp Mathis G8R engine. One remained active in France for several years, but both aircraft were ultimately scrapped."
