10/31/2012. Remarks by Walter van Tilborg and Johan Visschedijk: "The L 5 was again an original design homebuilt aircraft of Frenchman Émile Lucas and the type was intended for amateur construction. Work on the L 5 was started in 1969 and, depending on the engine used, the L 5 could be built as two, three, or four-seater and with choice of fixed or retractable tricycle or tail wheel type landing gear and with engines in the 100-200 hp range. The prototype L 5 was built by designer Emile Lucas with an 115 hp Lycoming O-235, a retractable tail wheel landing gear and the side-by-side two-seat aircraft was first flown on August 13, 1976. This aircraft was later also tested with a fixed and finally with a retractable tail wheel landing gear.

L-5. The general designation for aircraft completed by amateur constructors. Several had been built by 2000, including one as three-seater also built in France with an 145 hp Continental O-300-A engine. The first example built by an amateur constructor was flown in France during August 1980.
L 5-200. Designation for two-seat model with an 100 hp Continental O-200-A.
L 5-320. two/three-seater with an 150-160 hp Lycoming O-320.

The first aircraft of this type was built in France by Michel Devicq with a retractable tail wheel landing gear and it was first flown on March 14, 1988. This aircraft was the first plans-built L 5 to fly. Another French example with a 200 hp IO-360 engine flew in 2000.
