The Bleriot-SPAD S.46 was a small French airliner of the 1920s, developed from the Blériot-SPAD S.33. Like its predecessor, it was a conventional biplane that seated four passengers in an enclosed cabin while the pilot and occasionally a fifth passenger rode in an open cockpit. The S.46 had a redesigned wing of longer span and a far more powerful engine. The type was employed by Franco-Roumaine, which purchased 38 out of the 40 examples produced for use on their continental European routes.

In 1922 one of the S.46s, modified to use a more powerful 336 kW (451 hp) Lorraine 12E Courlis W-12 engine was redesignated S.86. In 1929 this was changed to a Hispano-Suiza engine in the same power range and redesignated S.126.

In 1925, the surviving 34 Franco-Roumaine aircraft were recalled to Blériot where they underwent remanufacture to incorporate various refinements. These refurbished aircraft were redesignated S.66. One of these aircraft was subsequently also modified to use a more powerful 336 kW (451 hp) Lorraine 12E Courlis W-12 engine and redesignated S.116.
