Design and development

The first Cessna design built in any numbers was the Cessna Model A, a four-seater with a mixed wood and steel-tube construction with fabric covering. The aircraft was built in a number of variants fitted with different engines.[1]

The prototype (Model AC) first flew in 1927 and the first production aircraft appeared in the following year.[2]

Fitted with a 120 hp (89 kW) Anzani 10 engine, 14 built.
Model AC

"Under the new formula, which made speed the most important characteristic of the modern airplane, the National Air Tour ended its 4,900-mile trip at Detroit last week as the most exacting and exhaustive demonstration ever conducted on a fleet of representative commercial and training airplanes. ... The flying of the pilots was declared perfect, and the technique and navigation of Miss Nancy Hopkins, only woman pilot, Edward Schneider and Truman Wadlow, three of the youngest pilots in the troupe, was equal to that of the older and more experienced racing pilots. In winning the Great Lakes Trophy for light planes in the tour Schneider beat out pilots who had a much better wingpower load ratio by sheer speed and good navigation. ...
