variants with their own articles=The Bleriot-SPAD S.56 was a family of prototype French airliners developed in the 1920s as various refinements of the S.33 design. All S.56 versions shared two new features: the first was a newly-designed, all-metal wing, replacing the wooden wing of earlier related designs and the second was a redesigned passenger cabin, replacing the S.33's four single seats in a row with two rows of double seats. A second access door was also added.

Variants

* S.56/1 - basic version with 194 kW (260 hp) Salmson CM.9 radial engine (1 built)

* S.56/2 - similar to S.56/1 with Gnome et Rhône-built Bristol Jupiter engine of 298 kW (400 hp) (1 built)

* S.56/3 - similar to S.56/2 with improved landing gear. (8 built)

* S.56/4 - major fuselage revision; cockpit relocated between engine and passenger cabin (in all previous S.33 derivatives, it had been aft of the cabin) and an extra double seat added to the cabin, increasing internal passenger capacity to six. (8 built, plus 2 modified from S.56/3s)

* S.56/5 - revised passenger cabin with four seats located in one compartment, and two in a second compartment that could be quickly converted to a freight hold (3 modified from S.56/3s)

* S.56/6 - similar to S.56/3 but customised for banner towing for the Air Publicité company
