The RA-14 Loisirs was a French two-seat high-wing light touring aircraft designed by Roger Adam shortly after World War II.

Design and production

The Loisirs ("Leisure") was designed in May 1945 by Roger Adam and built by Etablissements Aeronautiques R. Adam. It was a tube, wood and fabric two-seater suitable for amateur construction. It was a high-wing braced monoplane with a fixed tail-wheel undercarriage. The seats were positioned side-by-side.[2]

The company sold plans and manufactured parts for the aircraft which could be fitted with a range of engines of between 65 and 80 hp (48 and 60 kW). These included the Régnier 4D, Continental A65, Continental A75 and Continental C90 engines.

Variants

The design rights were sold in 1957 to the Maranda Aircraft Company of Canada who sold plans for amateur construction of the RA14BM1 Loisirs as the Falconar AMF-S14. More than 30 examples were built in North America.[2]
