Potez 43

Design and development

The plane was a development of Potez 36. First of all it featured new, slimmer fuselage, with three seats, instead of two. A disadvantage were non-folding wings, with shorter slats. The original Potez 430 first flew in June 1932, powered by a 78 kW (105 hp) Potez 6Ас radial engine . 25 examples of this variant were completed, followed by other variants, differing with the last digit in designation. Other variants built in significant numbers were Potez 431 and Potez 438. 161 of Potez 43 family were built in total.

Operational service

Two Potez 430s (registrations: F-AMBM and F-AMBN) took part in the Challenge 1932 international tourist plane contest. Pierre Duroyon took the 22nd place (for 43 starting and 24 finishing crews), while Georges Detre was disqualified due to low cruise speed.
