Bellanca 31-40 Senior Pacemaker

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 late 1920s Wright-Bellanca WB-2 design. The model numbers used by Bellanca in this period reflected the wing area and engine horsepower, each divided by ten. Like their predecessors, these were high-wing braced monoplanes with conventional tailwheel undercarriage.
