Cessna 140

File:Cessna 140 (NC89109) 03.jpg

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 {{convert|85|hp|kW|0|abbr=on}}. The Continental C-90-12F or C-90-14F of {{convert|90|hp|kW|0|abbr=on}} was optional, as was the {{convert|108|hp|kW|0|abbr=on}} Lycoming O-235-C1 engine, an aftermarket installation authorized in the type certificate. This model had a metal fuselage and fabric wings with metal control surfaces. The larger Cessna 170 was a four-seat 140 with a more powerful engine.{{Cite web|url= https://rgl.faa.gov/Regulatory_and_Guidance_Library/rgMakeModel.nsf/0/2d3c513e9ce4433886257ed2006fb509/$FILE/A-768_Rev_35.pdf|title =Type Certificate Data Sheet No. A-768|access-date = 19 August 2022|last = Federal Aviation Administration|author-link = Federal Aviation Administration|date = July 29, 2015}}

The Cessna 120 was an economy version of the 140 produced at the same time. It had the same engine as the 140, but lacked wing flaps. The rear-cabin "D" side windows and electrical system (radios, lights, battery and starter) were optional. A 120 outfitted with every factory option would be nearly equivalent to a 140, but the International Cessna 120/140 Association believes that no 120s were originally built this way. Despite this, many decades' worth of owner-added options have rendered many 120s almost indistinguishable from a 140 aside from the absence of wing flaps.{{cite journal | title = Budget Buy: Drag your tail - cheaply! | journal = AOPA Pilot | date = October 2011 | first = Ian J. | last = Twombly | volume = 54 | issue = 10 | pages = 60–66| url = http://www.aopa.org/members/files/pilot/2011/october/feature_cessna_140_budget_buy.html | access-date = 2011-10-27}} The 120 was dropped from production upon introduction of the 140A in 1949.

In 1949, Cessna introduced the 140A, a new variant with aluminum-covered wings and single wing struts instead of the fabric wing covering, dual "V" struts, and jury struts fitted on earlier models. Standard engines were the Continental C-90-12F or C-90-14F of {{convert|90|hp|kW|0|abbr=on}}, with the {{convert|85|hp|kW|0|abbr=on}} Continental C-85-12, C-85-12F, or C-85-14F engines optional. The spring-steel gear had been swept {{convert|3|in|cm|0|abbr=on}} forward on 120 and 140 models in late 1947 so landing gear extenders were no longer necessary to counter nose-over tendencies during heavy application of brakes; all 140A models had the improved gear legs.International Cessna 120-140 Association, [http://www.cessna120-140.org/forum/files/.pdf Landing Gear Legs and Extenders for the Cessna 120/140/140A Planes] {{webarchive|url=https://web.archive.org/web/20140109192305/http://www.cessna120-140.org/forum/files/.pdf |date=2014-01-09 }}Phillips, Edward H., : Wings of Cessna, Model 120 to the Citation III, Flying Books, 1986. {{ISBN|0-911139-05-2}}{{Cite web|url= https://rgl.faa.gov/Regulatory_and_Guidance_Library/rgMakeModel.nsf/0/bfc5f63870b57e1186257ed2006f214f/$FILE/5A2_Rev_22.pdf|title = Type Certificate Data Sheet No. 5A2 |access-date = 19 August 2022|last = Federal Aviation Administration|author-link = Federal Aviation Administration|date=July 29, 2015}} Despite these improvements, sales of the 140 lineup faltered, and the 140A comprised only seven percent of overall 120/140 production.

Common modifications to the Cessna 120 and 140 include:

• "Metalized" wings, where the fabric is replaced with light-gauge 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.{{cite web|url=http://www.micro-tools.net/pdf/Cessna/120-140_pm.pdf |title=Cessna Model 120 & 140 Parts Catalog |access-date=2009-08-08 |last=Cessna |author-link=Cessna |year=1954 |url-status=dead |archive-url=https://web.archive.org/web/20110716031253/http://www.micro-tools.net/pdf/Cessna/120-140_pm.pdf |archive-date=2011-07-16 }}
• Installation of rear-cabin "D" side windows on 120s that were not originally so equipped.
• 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.
• Installation of a more powerful engine. A popular conversion today is to replace the original C-85 or C-90 with a 100 hp (75 kW) Continental O-200. A kit is available to install a Lycoming O-320 but this conversion is less prevalent due to a roughly 100 lb (45 kg) weight penalty and a sharp increase in fuel consumption.
