The Cessna 120, 140, and 140A, are single-engine, two-seat, conventional landing gear (tailwheel), light general aviation aircraft that were first produced in 1946, immediately following the end of World War II.

Production ended in 1951, and was succeeded in 1959 by the Cessna 150, a similar two-seat trainer which introduced tricycle gear.

[2][3] The Cessna 140 was originally equipped with a Continental C-85-12 or C-85-12F horizontally opposed, air-cooled, four-cylinder piston engine of 85 hp (63 kW).

The rear-cabin "D" side windows and electrical system (radios, lights, battery and starter) were optional.
