S.56
Role Airliner
Manufacturer Blériot
First flight February 3 1923
Number built 22
Developed from Blériot-SPAD S.33

The Blériot-SPAD S.56 was a family of 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
