Touring and training aircraft, monoplane, single-engine, two-seater, mixed construction.

In 1938, the Ministry of Aeronautics organised a competition for a trainer and small touring aircraft intended for the RUNA (Royal National Aeronautics Union).
The first military order for 50 machines arrived in March 1939. In the summer of 1940, it was planned to assign the L.3s to the schools in Vibo Valentia, Perugia, Pescara, Fano, and Jesi. In 1941, the aircraft was also in Siena and Aquino.

After the armistice, around 15 examples were employed at the Gliding Centre.

Widespread in flying clubs until the 1970s, it disappeared in the following decade in the face of progressive diffusion of all-metal machines. 

Some specimens are preserved at the MUSAM in Vigna di Valle and at the Caproni Museum (Trento).
