The Bellanca 31-40 Senior Pacemaker and its derivatives were a family of a six- and eight-seat utility aircraft built in the United States in the late 1930s. They were the final revision of the original Wright WB-2 design Bellanca had bought in the late 1920s. The model numbers used by Bellanca in this period reflected the wing area (in this case 310 square feet) and engine horsepower (400 and up in this series) each divided by ten.
