    Learjet 31
    The Lear 31 first flew on 11th May 1987 and utilises the 35A's fuselage with the 55's wings and winglets. The aircraft uses the TFE73-2 turbofan giving a range of 1,200nm and has delta fins at the underside of the rear fuselage and features five port and six starboard windows. 37 aircraft were built as the basic model 31 before being superceded by the 31A in mid 1991.

    Learjet 31A
    242 Learjet 31A's were built before the aircraft was superceded by the Learjet 40.  This variant features an electronic cockpit and upgraded avionics  plus an increased speed of mach 0.81.  A 31ER version followed giving additional fuel capacity increasing the range to just over 1,00 nautical miles.

    Learjet 31ER
    . A 31ER version followed giving additional fuel capacity increasing the range to just over 1,500 nautical miles.
    .
    Learjet 35
    The 35 is a development of the 25, being stretched by 13inches plus a larger wingspan and TFE731-2 turbofans.  64 aircraft were built as the basic 35, superseded by 35A.  Seating eight passengers, early models have five starboard windows and four port, whereas later ones have six starboard plus five port.  The 35 first flew on 22nd August 1973. It can carry up to eight passengers.
    .

    Learjet 35A
    .
    The 35A is an upgraded version of the 35 powered by two TFE731-2-2B engines and has a range of 2,789 miles plus revised wing giving improved short field and low speed performance.  It first flew in 1976. Over 500 of both variants were built.

    Learjet 36
    Built in a new construction number sequence, the Lear 36 was externally similar to the 35, but differed in having a larger fuselage fuel tank giving 500 miles longer range but reducing cabin space to six passengers.

    < There are actually five windows on this pictured Lear 36A. The other is on the right and covered internally!

    Learjet 36A
    .
    The 36A is an upgraded version with the wing revisions as on the 35A.  64 36's were built in total, including six designated U-36A and used by the Japanese Self Defence Force as target tugs.

    Learjet 40
    The Learjet 40 is designed as a replacement for the Lear 31 and is a shortened version of the Learjet 45, truncated by 25.1 inches.  Seating 6 passengers, there are three fewer windows  and a reduced range of 1803nm.  It has been designed as competition to the Citation Encore and is slightly faster. It first flew on 31st August 2002, the prototype having been converted from the first Lear 45. First production aircraft flew on 5th September 2002 and certification of the $6.78 million aircraft was achieved in September 2003. .
    .
    Learjet 40XR
    . The Learjet 40XR is an uprated model 40 which was announced at the 2004 NBAA show.  With service entry in 2006, the XR features almost 1000nm greater range with greater climb and speed over the basic 40.  This is achieved by the use of Honeywell TFE731-20-BR engines, the same as on the 45XR.  Both versions of the 40 remain in production although the 40 is upgradable to XR standard.
    Learjet 45
    This version of the Learjet first flew on 7th October 1996 and is designed to fit in between the 31 and 60 models, seating up to eight passengers over ranges of up to 2,200 nm. It is powered by Garrett 731-20AR turbofans. Although certification took longer than anticipated,  around 250 had been built as of mid 2004.
    .
    Learjet 45XR
    The Learjet 45XR is a development of the 45, featuring a 1000lb increase in maximum take off weight, enhanced performance provided by upgraded TFE731-20BR engines plus new avionics and interior design.  Range is 2000nm and service entry took place in late 2003.  Eight passengers can be carried with full fuel load.  There is a subsequent increase in cost of $575,000 to $10.42 million.  Existing Lear 45's may be updated to the new specifications.
    .
    Learjet 55 Longhorn
    146 of all 55 models were built, these being the basic 55, the B,C and ER (2). The aircraft is larger in dimensions than the 35 and first flew on 19th April 1979, carrying the supercritical wing of the Lear 28. The ER is an extended range version.  There are four square windows on each side and power comes from two Garrett TFE731-3A turbofans. Range is around 2,492 miles and up to eleven passengers can be accommodated.  126 of the basic 55 were produced.  An LR variant gave extra fuel capaity with a reduced passenger load of seven with the XLR reducing this to six with even more fuel. Initially, three models were envisioned, the 54, 55 and 56.  However, the 54 and 56 designations were later abandoned leaving the 55 as the base model.
    .
    Learjet 55B
    This is an improved 55 featuring an electronic cockpit, new systems and autopilot plus thrust reversers and an increased gross weight.  Eight were built of this variant.
    .
    Learjet 55C
    Similar to the 55, but with the two ventral fins that were to become standard on the Lear 60.  It is powered by two TFE731-3A turbofans and can carry up to eight passengers over a greater distance than the basic  55 model. 14 were built in total.  An ER version gave a range of 2,079nm and an LR version gave 2,052nm.
    .
    Learjet 60
    In 1992 the Lear 55 was replaced by the 60 using a new c/n sequence. Differences include the two delta the fins on the lower rear fuselage and a 43 inche stretch.  The 60 first flew on 13th June 1991. Up to ten passengers can be carried in this Pratt & Whitney PW305 powered aircraft of which 293 had been produced by the time it was seperseded by the 60XR.
    .
    Learjet 60XR
    Announced at the NBAA show 2005, the Lear 60XR replaced the standard 60 in production in early 2007. The first airframe to be built as such was no 294.  Improvements include an upgraded interior and new avionics plus P&WC PW305A engines giving a speed of M079 and a range of 2451nm.  This version first flew on 3rd April 2006 with certification achieved on 28 September 2006 and first delivery made in August 2007, six months later than planned..
    ..
    Learjet 85
    Announced in October 2007, the Learjet 85 is sized between the Lear 60 and Challenger 300 and features seating for ten with a 3000nm range and M.82 speed. Powered by Pratt and Whitney Canada PW307B engines giving 6,100lb of thrust, the aircraft will be built wholly of composite materials in conjunction with Grob Aerospace.
    .
    Learjet C-21A
    Around 80 of the Lear 35A are operated by the United States Air Force as VIP transports, designated the C-21A.  Additionally, several are flown by the Brazilian Air Force as the C-35A.
