The Potez 32 and its military version the Potez 33 was a single-engine French monoplane transport built by Potez and based on the Potez 29 biplane.

Development

The Potez 32 used the same fuselage, tail unit and landing gear of the Potez 29, but was a high-wing strut-braced monoplane configured as either a five-passenger transport or mail plane. The first aircraft was flown in 1928 and was followed by 54 production aircraft.

The Potez 33 militarized version was first flown in 1928 and designed as a liaison / observation aircraft or could be used as a pilot or observer trainer. The Potez 33 was fitted with dual controls and had large observation windows, it also had a dorsal machine gun position and could carry light bombs on under-fuselage racks.
