The Cessna 120 and the Cessna 140 are single engine, two-seat, light general aviation aircraft that were first produced in 1946, immediately following the end of World War II.
Production ended in 1950, and was succeeded by the Cessna 150, a similar two-seat trainer which introduced a tricycle gear. The 120 and the 140, together, sold 7,664 copies in the five years that the aircraft were produced.
Development
Cessna 140
The Cessna 140 was originally equipped with an 85 or 90 horsepower (63 or 67 kW) Continental horizontally-opposed, aircooled, four-cylinder piston engine. This model has a metal fuselage and fabric wings with metal control surfaces. The larger Cessna 170 was a four seat 140 with a more powerful engine.
Cessna 140A
The final variant of the Cessna 140 introduced in 1949 was the 140A which had a standard Continental C90 engine producing 90 hp (67 kW), aluminum covered wings and a single strut replacing the dual "V" struts and jury struts fitted on earlier models.
Cessna 120
The Cessna 120 was an economy version of the 140 produced at the same time. It had the same engine as the 140, but did not have wing flaps. The cabin "D" side windows and electrical system (radios, lights, battery and starter) were optional.
Modifications
Common modifications to the Cessna 120 and 140 include:
"Metalized" wings, where the fabric is replaced with sheet aluminum, eliminating the need to periodically replace the wing fabric.
The installation of landing gear extenders to reduce the tendency of the aircraft to nose-over on application of heavy braking. These were factory-optional equipment.
Installation of rear-cabin "D" side windows on 120s that were not originally so equipped; some pilots feel that the 120's visibility to the rear is inadequate without them.
Installation of electrical systems on 120s that were not originally so equipped, allowing owners to install an electric starter, more sophisticated avionics and/or lights for night flying.
Type clubs
The Cessna 120 and 140 are supported by Aircraft Type Clubs, including the International Cessna 120-140 Association and the Cessna Pilots Association.

Cessna 120
Background
The Model 120 went into production in 1946. The high wing, two seat taildragger was the first of the post-war family of Cessna single engine aircraft. The metal fuselage/ fabric wing Model 120 was produced along with the 'deluxe' Model 140 which featured more refinements (such as a starter, manual flaps, extra windows, and in the case of the 140A - an all metal wing). The aircraft originally featured an 85hp engine, although a 90hp was later utilised. The Model 120 is reported to be reliable, well mannered, docile, and fun to fly. 2,172 Model 120s were built (as compared to 4904 Model 140s) up until the end of production in 1950. In 1957, the model 140 provided the basis for the development of the tricycle undercarriage model 150.
One Cessna 120 has appeared on the New Zealand register. The aircraft (illustrated below) first flew on August11, 1946 (c/n11102). It was acquired from the USA (as NC76662) by Parker Mudge of Queenstown and Nick Oppergard of Seattle, who went through the gauntlet of first of type with the New Zealand CAD. The aircraft has passed through several owners (including Ton Snelder and the Wakatipu Aero Club) and today it is one of two aircraft operated by the New Zealand Vintage AeroClub. In 2000 the aircraft was damaged in a landing accident (a freak wind gust overturned the aircraft). Normally based in Rotorua, the aircraft is presently in storage awaiting wing repairs.
