Developed from SEA IV

The Potez IX was an early airliner produced in France in the 1920s, a further development of the SEA IV that Henry Potez had co-designed during the First World War.[1][2] The design mated an entirely new fuselage to the wing and tail structures of the earlier military aircraft.[1][2][3] This fuselage was very deep, nearly filling the interplane gap, and carried within it a fully enclosed cabin with seating for four passengers.[1][2][3] The nose area was carefully streamlined[2] with curved aluminium,[4] but other aspects of the construction were conventional for the day; wooden structures skinned in plywood (the passenger cabin) or fabric (the rest of the aircraft).[5] The pilot sat in an open cockpit aft of the cabin.[2][5]

The prototype flew in 1921 and was followed by around thirty production examples that differed from it in having a larger tail fin and rudder.[2] The Compagnie Franco-Roumaine de Navigation Aérienne flew these[5] on routes linking Paris to London,[1] Strasburg,[5] Prague,[5] Warsaw,[1] and Budapest[1] until 1928.[1]

The Potez IX S, a one-off modified version with wings of larger area,[2] flew in the Grand Prix de l'Aéro Club de France in June 1921 with Gustave Douchy at the controls.[6] Douchy was disqualified in the third stage of the competition.[6]
