SRCM 153 Joigny

09/30/2011. During the 1950s the SRCM (Société de Recherches et de Constructions Mécaniques), with offices at Courbevoie, Paris, France, and works at Joigny (78 mls, 125 km south-east of Paris) had specialized for some years in the design and manufacture of hydraulic equipment for light aircraft. It has also built for the Aero-Club de Joigny and other customers a number of light aircraft, including six CAB Minicabs, two CAB Supercabs and several Jodel 65's.

After failing to obtain a license for manufacture of the Supercab and for the Aviamilano F.8L Falco, SRCM decided to design a completely new three-seat light monoplane. This materialized as the SRCM-153 Joigny, construction of the prototype commenced in April 1958 and it was first flown in June 1959, under the provisional registration F-WIRZ.

On June 29, 1960 the aircraft was reregistered F-BIRZ (Henk Wadman Collection) after it received its CofA; it was demonstrated at the 1963 Paris Air Salon. The sole SRCM-153 was deregistered on January 29, 1979 as condemned. It reappeared on the French register in the homebuilt category as F-PIRZ (Walter van Tilborg Collection) on November 23, 1983. Two years later, November 19, 1985 it was again deregistered, this time as 'destroyed', it had crashed near Coudeville the previous August 4.
