The Cessna 120 and the Cessna 140 are single engine, two-seat, light general aviation aircraft that were first produced in 1946, just following the end of World War II.
塞斯纳120及140单发双座轻型飞机，在二战结束后，于1946年推出。
Production ended in 1950, and was later succeeded by the Cessna 150, a similar two-seat trainer which introduced a tricycle gear.
1950年停止生产，被Cessna150(前三点起落架)取代。
Between the 120 and the 140, Cessna sold 7,664 airplanes in the five years that the aircraft were produced.
5年间，Cessna 120 与 140，共销售了 7664 架。

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 essentially a four seat 140 with a more powerful engine.
Cessna 140
Cessna 140 配备了85或90马力(63或67KW)横向风冷4缸活塞式发动机。这种模式有一个金属机身和机翼织物与金属
控制面。略大一些的塞斯纳170是一个4座位140个，与一个更强大的引擎。
Cessna 140A
1947 Cessna 120The 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 140A
140A 使用单翼撑取代了之前的V型结构，并升级为90马力(67KW)发动机。
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.
Cessna 120
Cessna 120是一个经济版本的140，同时推出。它们使用相同的引擎，但 120 没有襟翼。
电气设备是可选的。
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.
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 more sophisticated avionics and/or lights for nighttime flying.
Type clubs
The Cessna 120 and 140 are supported by a number of Aircraft Type Clubs, including the International Cessna 120-140 Association and the Cessna Pilots Association.
大意：铝蒙皮能减少维护；起落架的设计的改进能改善着陆刹车性能；后方侧窗能使飞行员后视的感觉好。
