The '''Learjet Model 35''' and '''Model 36''' are a series of American multi-role business jets and military transport aircraft manufactured by Learjet between 1973 and 1993.<ref name="aircharterservice.com" /> When used by the United States Air Force, they carry the designation '''C-21A'''. Learjet was acquired by Bombardier Aviation in 1990 as a subsidiary, so the aircraft is also known as the '''Bombardier Learjet 35'''.<ref name="aircharterservice.com" />

When first released in 1973, the Learjet 35 was among the fastest medium haul jets of its era. As of 2020, more Learjet 35s have been sold than any other Learjet aircraft, with many still in service after 50 years.

The aircraft are powered by two Garrett TFE731-2 turbofan engines. Its cabin can be arranged for six to eight passengers. The longer-range Model 36 has a shortened passenger area to provide more space in the aft fuselage for fuel tanks.

The engines are mounted in nacelles on the sides of the aft fuselage. The wings are equipped with single-slotted flaps. The wingtip fuel tanks distinguish the design from other aircraft having similar functions.

==Development==

The concept which became the LJ35 began as the Learjet 25BGF (with GF referring to "Garrett Fan"), a Learjet 25 with a then-new TFE731 turbofan engine mounted on the left side in place of the 25's General Electric CJ610 turbojet engine. This testbed aircraft first flew in May, 1971.<ref name="alnet_35_36">[http://www.airliners.net/info/stats.main?id=265 The Learjet 35, 36 & 31] at Airliners.net</ref> As a result of the increased power and reduced noise of the new engine, Learjet further improved the design, and instead of being simply a variant of the 25, it became its own model, the 35.

By 2018, 1980s Learjet 35As start at $500,000.<ref name=AINdec2018>{{cite magazine |url= https://www.ainonline.com/sites/default/files/full-issues/ain_1218.pdf |title= For many models, market hitting the apex |magazine= Aviation International News |author= Mark Huber |date= December 2018 |pages= 20–21, 24 |access-date= 2018-12-27 |archive-date= 2018-12-27 |archive-url= https://web.archive.org/web/20181227181555/https://www.ainonline.com/sites/default/files/full-issues/ain_1218.pdf |url-status= dead }}</ref>

==Operational history==

When released in 1973, Learjet's marketing claimed that the Learjet 35 was among the fastest business jets in its class.<ref name="internationalaviationhq" /> In 1976 American professional golfer Arnold Palmer used a Learjet 36 to establish a new round-the-world class record of 22,894 miles (36990 km) completed in 57 hours 25 minutes 42 seconds.<ref name="palmer">{{Cite web |url=http://www.arnoldpalmer.com/EXPERIENCE/WHATSNEW/ARCHIVE/2005/10/palmer_insures.aspx |title=Palmer Insures Proficiency in Cessna Citation X Jet - Arnold Palmer News |access-date=2012-05-25 |archive-url=https://web.archive.org/web/20160306112041/http://arnoldpalmer.com/experience/whatsnew/archive/2005/10/palmer_insures.aspx |archive-date=2016-03-06 |url-status=dead }}</ref>

Because of its speed and long range, leaders of many nations bought the aircraft as their primary or secondary jet. Countries who did this include: Brazil, Chile, Finland, Switzerland and Saudi Arabia among others.

During the Cold War, the Finnish Air Force used the Learjet 35/36 as a shorter range AEW&C aircraft, for monitoring Soviet bombers and fighter jets coming over the Baltic Sea and over the Arctic. Learjet 35s made the bulk of Argentina's Escuadrón Fénix flights during the 1982 Falklands War mainly on diversion and reconnaissance flights.

Production on the 35/36 series ceased in 1994.<ref name="spectra">{{cite web |title=Learjet 30 Series Information |url=http://www.spectrajet.homestead.com/learjet30info.html |website=Spectra Jet |access-date=22 September 2024 |archive-url=https://web.archive.org/web/20060311031315/http://www.spectrajet.homestead.com/learjet30info.html |archive-date=11 March 2006}}</ref> There are still well over 500 Learjet 35s in service around the world, despite the model being almost 50 years old.<ref name="internationalaviationhq" />

{{as of|2018|January}}, the U.S. National Transportation Safety Board database<ref name="ntsb4">[https://www.ntsb.gov/_layouts/ntsb.aviation/Results.aspx?queryId=310df1db-636a-49f5-8846-8b7736d24ba2 NTSB database query]</ref> lists 25 fatal accidents for the 35/35A, and two for the 36/36A.

===Learjet 35=== The original '''Model 35''' was powered by two TFE731-2-2A engines and was {{convert|13|in}} longer than its predecessor, the Model 25. First flight of the prototype Model 35 was on 22 August 1973, and the aircraft was FAA certified in July, 1974. It could carry up to eight passengers. There were 64 base-model 35s built.<ref name="spectra"/>

===Learjet 35A=== The '''Model 35A''' is an upgraded Model 35 with TFE731-2-2B engines and a range of 2,789 miles, with a fuel capacity of {{convert|931|usgal|L}} with refueling accomplished at ground level through each wingtip tank. It was introduced in 1976, replacing the 35. Over 600 35As were built, with a production line that ended with serial number 677, in 1993.<ref name="spectra"/>

;Learjet 36A :Like the 35A, the '''Model 36A''' has upgraded engines and a higher maximum gross weight. It was introduced in 1976, replacing the 36.<ref name="spectra"/>

=== Military variants === ;C-21A :The '''C-21A''' is a United States military designation for an "off the shelf" variant of the Learjet 35A for the United States Air Force, with room for eight passengers and 42 ft<sup>3</sup> (1.26 m<sup>3</sup>) of cargo. In addition to its normal role, the aircraft is capable of transporting litters during medical evacuations. Delivery of the C-21A fleet began in April 1984 and was completed in October 1985.

:There are 38 Air Force active duty aircraft, and 18 Air National Guard aircraft in the C-21A fleet. On 1 April 1997, all continental U.S.-based C-21As were realigned under Air Mobility Command, with the 375th Airlift Wing at Scott Air Force Base, Illinois, as the lead command. C-21As stationed outside the continental United States are assigned to the theater commanders.<ref name="global">[http://www.globalsecurity.org/military/systems/aircraft/c-21.htm C-21A Learjet] at GlobalSecurity.org</ref>

== Success and popularity ==

When first released in 1973, the Learjet 35 was among the fastest medium haul jets of its era. As of 2020, more Learjet 35s have been sold than any other Learjet aircraft.<ref name="internationalaviationhq" />

As a private jet the Learjet 35 was popular because of its good range (it can fly 2,056 miles nonstop), takeoff and landing performance (its Honeywell engines provide 3,500 pounds of thrust and can land on short runways at regional airports), fast cruise capabilities (it can cruise at speeds as high as 451 knots true airspeed (KTAS), or 424 KTAS with four passengers), good handling characteristics, a low fuel burn, and comfortable cabins.<ref name="impdb.org" /><ref name="aircharterservice.com" /><ref name="jetadvisors" /> Together with the Learjet 25, the Learjet 35 was a favorite among celebrities.<ref name="bbc.com" /><ref name="impdb.org" />

The Learjet 35 is one of Bombardier's most successful light jets and remains one of the fastest in its category on the private jet charter market.<ref name="aircharterservice.com" />

The Learjet 35 has been used to film aerial sequences for movies. A camera-equipped Learjet 35 was used to film some of the aerial sequences for the 1980 film ''The Final Countdown''.

The Learjet 35 also appeared in the movies Between the Lines (Ep. 3.05, 1994), A Wing and a Prayer (1998 TV Movie), Free Fall (1999), Prison Break (season 4) (Ep. 4.18, 2008), The Bourne Legacy, Fast & Furious 6 (2013), and many others.<ref name="impdb.org" />

A 2018 survey by ''Corporate Jet Investor'' found 14.9% of Americans recognized the Learjet brand compared with 12.5% for Boeing.<ref name="forbes.com" />
