Derived from the Potez 29, the Potez
32 five-passenger transport or mail-plane retained the fuselage, tail unit and landing gear of its predecessor, but was a strut-braced high-wing monoplane. First flown in 1928, the prototype was followed by 54 production aircraft. An initial difference in comparison with the Potez 29 was the employment of a lower-powered, and thus cheaper and more economical, Salmson radial engine; later aircraft had the higher-powered Jupiter. The type was operated by CIDNA, Air Orient and Aeropostale, and 12 were exported to Canada.
The Potez 33 prototype, tested in March 1928, was a militarised version of the Potez 32 intended for liaison and observation, or as a trainer for pilots and observers. It had dual controls as standard, introduced large observation windows, and had a dorsal machine-gun position; light bombs could be carried.
