This aircraft was an all-metal twin boom low wing monoplane built by SPCA in order to meet the requirements of the Technical Aeronautic Service (Service Technique de L'Aéronautique) of the French government towards the end of the 1920s for a bomber and reconnaissance aircraft type designated as Multiplace de Combat.[3]

Two units of the SPCA 30 were built, registration F-AKCA and F-AKCB. The first one was fitted with two Lorraine-Dietrich 18Kd water-cooled W engines engines[4]and the second one with two Hispano-Suiza 12Nb engines, both giving about 485 kW (650 hp). The original bulky landing gear was later replaced by a lighter one.

Operational history

The SPCA 30 was the only twin boom aircraft that entered the contest, but both prototypes of this aircraft were ignored in favor of the competing Amiot 143 after evaluation. Other Multiplace de Combat aircraft prototypes built by other companies at the time such as the Blériot 137 and the Breguet 410 underwent a similar fate as the SPCA 30.[5]
