The '''Learjet 45''' (LJ45) is a mid-size [[business jet]] aircraft produced by the [[Learjet|Learjet Division]] of [[Bombardier Aerospace]].

The Model 45 was the first all-new design since the original Learjet, and significantly altered the Learjet line. Through its four primary variants – the original Model 45, the Model 45XR, Model 40 and Model 40XR – it was the Learjet Division's principal product from the 1990s until the introduction of the Model 75 variant in 2012.<ref name="swiss_flying">{{cite web |url=http://www.flyingmag.com/aircraft/jets/lear-45xr-swiss-army-knife-jets |title=Lear 45XR: The Swiss Army Knife of Jets: Refining and redefining the super-light jet category |last=Charles |first=Michael Maya |date=November 18, 2010 |website=Flying Mag |publisher=Bonnier Corporation |access-date=April 5, 2017 |archive-date=July 5, 2017 |archive-url=https://web.archive.org/web/20170705213650/http://www.flyingmag.com/aircraft/jets/lear-45xr-swiss-army-knife-jets |url-status=dead }}</ref><ref name="learjet_bizjet">{{cite web |url=https://www.bjtonline.com/business-jet-news/learjet-45-45xr |title=Learjet 45 & 45XR |last=Huber |first=Mark |date=June 2007 |website=Business Jet Traveller |publisher=The Convention News Co |access-date=April 5, 2017 }}</ref><ref name="used_bca">George, Fred, [http://aviationweek.com/business-aviation/used-aircraft-report-learjet-4545-xr "Used Aircraft Report: Learjet 45/45 XR: Fast, efficient, reliable and now less maintenance-intensive,"] March 28, 2017, ''Business & Commercial Aviation,'' Retrieved April 10, 2017.</ref>

==History==
===Development and production===
[[File:Beauty standing still (426105349).jpg|thumb|On ground]]

The Model 45 was developed in the 1990s as a competitor in the "super-light" business jet category, a rival to the popular [[Cessna Citation Excel]] / [[Cessna Citation XLS|XLS]] – but sacrificing the Cessna's stand-up room for the Learjet family's traditional high-speed performance.<ref name="swiss_flying" /><ref name="learjet_bizjet" /><ref name="used_bca" />

The Model 45 was Learjet's first completely new ("clean sheet") design since the company's first aircraft (all other models having been evolved from the original 1963 Learjet design, the [[Learjet 23|Model 23]]). The Model 45 was developed to make Learjets fundamentally more competitive against newer designs from competing manufacturers. But, as a clean-sheet design (starting from scratch), being built to more rigorous (FAR Part 25) rules than previous Learjets, the aircraft's development took substantially longer than that of previous Learjet models.<ref name="learjet_bizjet" />

The development of the LJ45 began in 1989,<ref name="learjet_bizjet" /> but was not announced by Bombardier until September, 1992. First flight of the prototype aircraft took place on October 7, 1995 – the 32nd anniversary of the first flight of the original [[Learjet 23]].  [[Federal Aviation Administration|FAA]] [[Type certificate|certification]] was delayed, and finally granted in September 1997, with the first customer aircraft subsequently delivered in mid-1998.<ref name="2-FirstLJ45" /><ref name="FirstLJ45" /> The aviation magazine ''[[Flying (magazine)|Flying]]'' reported that the Lear 45 was first certified under FAR Part 25 (transport category rules) in 1998.<ref name="swiss_flying" />

Initially, delays in production resulted in frustrated customers and lost or delayed revenues. Some customers' orders were delayed more than two years.<ref name="learjet_bizjet" />

===Deliveries and difficulties===
[[File:N300JC Learjet Inc 45 C-N 340 (5394534073).jpg|thumb|In flight]]

By late 2006, Learjet had delivered over 300 Model 45s (40 of which were its improved version, the Model 45XR).<ref name="learjet_bizjet" /> By November 2010, over 500 of the Model 45 and 45XR had been delivered.<ref name="swiss_flying" />

Initially, numerous mechanical and electrical problems began appearing in the aircraft after delivery –  including cracked windshields, problems with pressurization, fried power distribution panels, and inappropriate alarms. These and other problems commonly forced Model 45 operators to ground their aircraft about once a month, limiting their use.<ref name="learjet_bizjet" />

Problems came to a head in August 2003, when the FAA discovered a defective fastener for the Model 45's horizontal stabilizer could break, sending the airplane into a fatal dive. The FAA grounded all Learjet 45s, across the nation, and they all sat on the ground for a month, while the manufacturer struggled to develop a fix and get it to aircraft in the field.<ref name="learjet_bizjet" /><ref name="faa_grounds">{{cite web |url=http://www.iasa-intl.com/folders/belfast/storylear45.htm |title=FAA Grounds All Learjet Model 45 Business Jets |last=Phillips |first=Don |date=August 12, 2003 |website=iasa-intl |access-date=April 5, 2017}}</ref>

By 2007, Model 45 operators were said to have a "love-hate" relationship with the aircraft – appreciating its exceptional combination of performance, payload and economics, but frustrated by frequent maintenance problems, often grounding the aircraft, and difficulty getting prompt and adequate product support and parts.<ref name="learjet_bizjet" /><ref name="ain_2004">Gilbert, Gordon, [http://www.ainonline.com/aviation-news/aviation-international-news/2006-10-04/2005-ain-product-support-report "2005 AIN Product Support Report."] October 4, 2006. ''Aviation International News.'' Retrieved April 5, 2017.</ref> However, 10 years later, a 2017 "Used Aircraft Report" by ''Business & Commercial Aviation'' magazine indicated that owners now regard the aircraft as "gas-and-go airplane" and credit it "with great reliability," and the article's author, B/CA senior editor Fred George, describes it as "a rock-solid reliable workhorse."<ref name="used_bca" />

By 2018, Learjet 45/45XRs were priced at $1.5–4.9 million.<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>

==Design and manufacturing==
[[File:Bombardier Learjet 45 XR interior.JPG|thumb|Flat-floor cabin]]
[[File:VH-SQD Bombardier Learjet 45 Singapore Flying College (9527311466).jpg|thumb|Flight deck]]

In size, the LJ45 and LJ45XR fit between the smaller [[Learjet 31]] and [[Learjet 40]], at the low end,  and the larger [[Learjet 60]] at the top of the Learjet product line. It offers the operating economics typical of a "light" business jet, but the performance and comfort of a "mid-size" business jet.<ref name="learjet_bizjet" /><ref name="used_bca" />

It has a {{convert|1971|nmi|adj=on}} range at Mach 0.81 with four passengers on board.

The plane was designed around a flat-floor cabin,<ref name="learjet_bizjet" /><ref name="used_bca" /> with a non-circular cross-section for additional headroom.<ref name="used_bca" /> Typical interior configuration is eight passenger seats, in a double-[[club seating]] arrangement, and a fully enclosed toilet (usable as a 9th seat) and an adjoining 15-cubic-foot baggage area.<ref name="swiss_flying" /><ref name="used_bca" /> An external 50-cubic-foot baggage area is also provided.<ref name="used_bca" />

The Model 45 was Learjet's first "clean-sheet" (all-new) design since the development of the original [[Learjet 23|Model 23]].<ref name="learjet_bizjet" /> (All previous models had been derivatives of the Model 23, with the wide-fuselage [[Learjet 55|Model 55]] and [[Learjet 60|Model 60]] utilizing the basic wing design originating in the Model 23, but with extensions and winglets; some, however, view the Model 55 as a "clean sheet" design, also.)<ref name="used_bca" />

Previous Learjet designs had used rigorous, extensive "[[fail-safe]]" structures in the wing and tail assemblies, with numerous [[wing spar]]s providing a highly reinforced structure (derived from the Swiss-designed [[FFA P-16|P-16]] prototype fighter that was the original basis for the first Learjet)<ref name="lear_gene">{{cite web |url=http://airportjournals.com/the-lear-gene/ |title=The Lear Gene |author=<!--Not stated--> |date=November 1, 2005 |website=Airport Journals |access-date=April 5, 2017 }}</ref> – but the Model 45, instead, used a lighter, less-robust structure, affording less cost in manufacture and lower aircraft empty weights, resulting in improved capacity, efficiency and some performance enhancement (for a given amount of engine power), at a competitive price.<ref name="swiss_flying" />

Outwardly, however, the Model 45 retained the traditional Learjet appearance, with its semi-swept wing, T-tail, sharp nose, and wrap-around windshield – while using engines and avionics similar to those in the [[Learjet 60|Model 60]].<ref name="swiss_flying" />

It also incorporated two conspicuous  modifications pioneered on earlier Learjets: the "delta fins" (twin ventral fins, positioned to help stabilize the aircraft in flight, and help right the aircraft in a deep [[aerodynamic stall]]) – and [[winglets]] (upturned wingtips to reduce [[induced drag]] and improve stability). Among other characteristics, the design has reportedly yielded the most benign stall characteristics of any "light" business jet to date (as of 2017).<ref name="swiss_flying" /><ref name="used_bca" />

The Model 45 cockpit is equipped with a four-screen [[Honeywell Primus]] 1000 EFIS avionics system,<ref name="swiss_flying" /> but it uses obsolete [[Cathode-ray tube|CRT]] screens, rather than modern [[Liquid-crystal display|LCD]] screens, in resulting substantial maintenance costs (though a $300,000 LCD-display upgrade is available).<ref name="used_bca" />

The aircraft is powered by two [[FADEC|DEEC]]-controlled [[Honeywell TFE731]]-20-AR [[turbofan]] engines, rated at 3,500 pounds thrust, each, in sea-level temperatures up to 88&nbsp;°F – a fuel-efficient, "understressed," derated version of the 4,435&nbsp;lb thrust TFE731-40 – developed specifically for the Learjet 45. Recommended engine TBO (time between overhauls) is 5,000 hours.<ref name="swiss_flying" /><ref name="airliners">{{cite web |url=http://www.airliners.net/aircraft-data/bombardier-learjet-45/127 |title=Bombardier Learjet45 Specifications |author=<!--Not stated--> |website=Airliners |publisher=Leaf Group Ltd |access-date=April 5, 2017 }}</ref><ref name="learjet_bizjet" /><ref name="used_bca" />

At normal atmospheric conditions, zero-wind takeoff runway requirements range from 4,200 feet (for a stripped, basic plane with a [[basic operating weight]] of 11,700 pounds) to 5,040 feet for a fully equipped model, with [[auxiliary power unit]] and other upgrades (14,200&nbsp;lbs).<ref name="used_bca" />

However, the engine exhibits poor performance in high-[[density altitude]] situations (such as takeoff from hot, humid or high-elevation airports), often resulting in long runway requirements. (Engine power deficiency in high-density altitudes was largely resolved by the engine upgrade to the -20BR engine variant in the Learjet 45XR variant of the Learjet 45 – an engine upgrade which is also available as a retrofit to the older Learjet 45, and widely recommended.)<ref name="swiss_flying" /><ref name="airliners" /><ref name="learjet_bizjet" /><ref name="used_bca" />

An internal auxiliary power unit, for ground use, provides electrical and pneumatic power, permits easy starts, without ground power units, and enables aircraft cooling or heating while on the ground, without the engines operating. However, the auxiliary power unit was initially optional, rather than standard, equipment.<ref name="swiss_flying" /><ref name="airliners" /><ref name="learjet_bizjet" /><ref name="used_bca" />

The wing has 13 degrees of [[swept wing|wing sweep]] with a [[supercritical airfoil]] optimized for cruise flight at Mach 0.78. Though there are no [[leading-edge slats]] or [[wing fence]]s, the wing has [[vortilons]] on the leading edge, to avoid [[spanwise flow]], and small metal triangles on the leading edge to minimize airflow separation during flight at a high [[angle of attack]].<ref name="swiss_flying" /><ref name="used_bca" />

The Lear 45 was certified under FAR Part 25 (transport category rules), rather than FAR Part 23 (often used in earlier business jets). The stricter Part 25 certification requires greater system redundancy, and requires that the airplane reliably meets the performance numbers published in the aircraft's FAA-approved Pilot's Operating Handbook (POH).<ref name="swiss_flying" /><ref name="learjet_bizjet" />

Dual-wheel, [[trailing link]], main landing gear is provided, with digital nosewheel steering facilitating tight turns. Single-point pressure refueling is also provided, expediting turnarounds.<ref name="swiss_flying" />

[[De Havilland Canada]] builds the LJ45's wings, and Bombardier subsidiary [[Short Brothers]] of [[Belfast]], [[Northern Ireland]], builds the [[fuselage]] and [[empennage]].

==Variants==
===Model 45XR===
[[File:Bombardier Learjet 45XR - 33 - closeup portside door open.jpg|thumb|Learjet 45XR at the 2007 [[Paris Air Show]]]]

The Learjet 45XR is an upgraded version of the Model 45, introduced in June 2004, offering substantially higher takeoff weights, faster cruise speeds and faster time-to-climb rates than the Model 45, chiefly through modifications to the engine.<ref name="swiss_flying" /><ref name="learjet_bizjet" /><ref name="used_bca" />

The XR allowed a [[gross weight]] 1,000 pounds greater than the original Model 45, greatly increasing payload and fuel/range options. The aircraft also has exceptionally short runway requirements for mid-size bizjets, capable of loaded flights from 4,000-foot runways.<ref name="swiss_flying" /><ref name="learjet_bizjet" />

The 45XR's performance and specifications increases are due to the upgrading of the engines to the TFE731-20BR configuration, flat-rated to 3,500 pounds thrust, even at 104 degrees Fahrenheit, well above the 88-degree mark for that power from the original Model 45's TFE731-20 engines.<ref name="swiss_flying" /><ref name="used_bca" /><ref name="wingsoverkansas1">[http://www.wingsoverkansas.com/news/article.asp?id=358 "Bombardier Aerospace Launches Learjet 40XR High Performance Light Jet." from ''Wings over Kansas''] {{webarchive|url=https://web.archive.org/web/20061114105943/http://www.wingsoverkansas.com/news/article.asp?id=358 |date=November 14, 2006.}}</ref>

The Model 45 cockpit is equipped with a four-screen [[Honeywell Primus]] 1000 EFIS avionics system,<ref name="used_bca" /> with [[TCAS]] and [[EGPWS]].<ref name="swiss_flying" />

LJ45 owners can upgrade their aircraft through the incorporation of several service bulletins.<ref name="wingsoverkansas1"/><ref name="used_bca" />

===Model 40===
{{main|Learjet 40}}
The Model 40, first delivered in 2003, is a two-foot (24.5 inches) shorter variant of the Model 45, with less passenger room, but otherwise comparable characteristics and performance data. The model 40 also lacked an auxiliary power unit.<ref name="swiss_flying" />

===Model 40XR===
The Model 40XR, introduced in 2004, is a higher-performance variant of the Model 40, with the same modifications as used to convert the Model 45 into the Model 45XR.

===Model 75===
{{main|Learjet 75}}
The Learjet Model 75 variant, first delivered in 2012, is essentially a Model 45XR with more modern engines, engine systems, and Garmin 5000 avionics, and more efficient winglets.<ref name="operators">George, Fred, [http://aviationweek.com/business-aviation/operators-survey-bombardier-learjet-7075 "Operators Survey: Bombardier Learjet 70/75: Strong resurgence of the last Learjet."] March 28, 2017. ''Business & Commercial Aviation.'' Retrieved April 10, 2017.</ref><ref name="used_bca" />

The Model 75's Honeywell TFE731-40BR engines yield 10% more takeoff thrust (3,850 pounds) than the -20BR engines powering the Model 45XR, cutting required runway length 12%, allowing a sea-level, standard-day takeoff within 4,440&nbsp;ft., (versus the Model 45XR's fully equipped need for 5,040&nbsp;ft). In these conditions, the Model 75 can take off from a 4,500-foot runway, with a full load of passengers and fuel, and fly 1,800 nautical miles (2,070 statute miles).<ref name="operators" />

As with the original Model 45, the Model 75 was initially delivered in a stripped-down form, with many features only offered as options, rather than as standard equipment). However, the aircraft does come equipped with an auxiliary power unit, and thrust reversers (rare in light business jets). Early units had minor quality problems and defects.<ref name="operators" />

The Model 75 was first FAA-certified in 2013, and took the place of the Model 45XR, becoming the division's principal product. Since 2015 (as of 2017), it is the division's only product.<ref name="operators" /><ref name="cert">McMillin, Molly, [http://www.kansas.com/news/business/aviation/article1127710.html  "Bombardier's Learjet 75 gets FAA certification."] November 15, 2013. ''Wichita Eagle.'' Retrieved April 5, 2017.</ref>

===Model 70===
{{main|Learjet 75}}
The Model 70, introduced in 2013, is a shortened variant of the Model 75 – alternatively described as an upgraded Model 40XR, with the same modifications as used to convert the Model 45XR into the Model 75. It was far less popular than the Model 75, and was dropped from the Learjet line in 2015.<ref name="operators" />

==Accidents and incidents==
* October 27, 1998, N454LJ was destroyed after loss of control during a landing roll and collision with a ground vehicle at the [[NASA]] [[Wallops Flight Facility]], [[Wallops Island]], Virginia. The plane was conducting water ingestion tests for a Goodyear nose wheel tire. The copilot and the flight test engineer received minor injuries.<ref>{{cite web |title=Aviation Accident Final Report |url=https://reports.aviation-safety.net/1998/19981027-1_LJ45_N454LJ.pdf |publisher=[[National Transportation Safety Board]] |access-date=February 1, 2022 |date=April 6, 2001}}</ref>
* August 2003, a defective fastener for the Model 45's horizontal stabilizer failed in flight, creating the risk of a crash, which was averted. This event led to the FAA issuing an [[Airworthiness Directive]] grounding all Learjet 45s, nationwide, for a month, while the manufacturer developed a fix and got it out to aircraft in the field.<ref name="learjet_bizjet" /><ref name="faa_grounds" />
* June 1, 2003, approximately 1426 local time, a Learjet 45, registration number I-ERJC, operated by [[Eurojet Italia]], crashed shortly after take-off from [[Linate Airport]] in [[Milan, Italy]]. The airplane reportedly struck a flock of birds shortly after takeoff and crashed into an industrial building while attempting to return to airport.
