The structurally very similar models Cessna 120 and Cessna 140 were light aircraft from the American manufacturer Cessna , which were built from 1945 to 1951 with a number of 7664 (more than 2000 Cessna 120 and over 5000 Cessna 140).

Both variants were all-metal cabin shoulders with braced, fabric-covered wings and rigid tail wheel landing gear; they offered space for two people.

The Cessna 140 completed its maiden flight on June 28, 1945; the simplified Cessna 120 followed in 1946.
They were the original model of all single-engine Cessnas up to the present day and designed as simple and inexpensive aircraft that should contribute to the spread of aviation.


The Cessna 140 was the more luxurious version of the two models. It had flaps lift aid , extra rear side windows and a complete electrical system, which allowed, on request, a radio or navigation equipment, landing lights, starter motor and an additional fuel pump to retrofit. The drive consisted of a Continental - piston engine C-85-12F with 63 kW (85 hp), an air-cooled 4-cylinder horizontally opposed engine. A C-90 engine with 67 kW (90 hp) was optionally available. In 1946 a Cessna had to pay $ 140,3495.

The Cessna 120 was the (later released) economy version of the Cessna 140 and flew for the first time in 1946. It had the same drive, but no landing flaps or rear side windows. An on-board electrical system was only available as an additional option. However, most of the Cessna 120s were equipped or retrofitted with it, as well as with side windows, so that they could hardly be distinguished from the Cessna 140 - with the exception of the missing landing flaps. Production of the Cessna 120 ceased in 1949 with the introduction of the 140A.

The Cessna 140A was produced towards the end of the series from 1949 to 1951. They were only available with the Continental C90 engine with 67 kW (90 PS). Cessna 140A models can be easily distinguished from the other Cessna 140 or 120 models by the simple wing support. In the previous models, on the other hand, there is a double, V-shaped support. Another distinguishing feature is the paneling of the wings with aluminum . The maximum take-off weight has been increased by around 23 kg to 681 kg.

Despite these and other improvements, production of the 140 series began to stall, and the number of 140A's built represented only 7 percent of the total production of the 120/140 series. The production of the series ended in 1951.

The Cessna 150 is seen as the successor model, although production did not begin until 1957.
