LEAR JET AIRCRAFT HISTORY
Lear 60XR (2007 to 2013 - SN 319 to SN 424)
The Lear 60XR is an improved Lear 60 with an upgraded cabin, Rockwell Collins Pro Line 21 advanced avionics suite and three disc steel wheel brakes . The cabin layout was also improved. The new cabin design includes a window in the lavatory area. Deliveries of the Learjet 60XR began in 2007.
LEAR 60 (1993 to 2006 - SN 1 to SN 318)
The Learjet 60 is an improved version of the Learjet 55, with a 3½-foot longer fuselage and more powerful Pratt & Whitney Canada PW305 turbofan engines. It first flew on 10 October 1990 and received FAA certification in January 1993. The avionics are upgraded to the Collins Pro-Line 4 systems and the single ventral fin was replaced with two ventral fins that Learjet called "Delta Fins" to improve stall characteristics and promote aerodynamic stability. The improved Learjet 60 first flew in June 1991 and deliveries started after certification in 1993.
LEAR 55 ( 1981 to 1990 - SN 3 to SN 147)
The Lear 55 was Lear's entry into the medium-sized business jet field. In designing the 55, Learjet utilizes the earlier Longhorn 28/29 wing with winglets and married it to a larger fuselage. The step-down aisle in the cabin has 5 ft 9 inches of headroom. 124 Lear 55's were built. The Lear 55B - with SN 127 to SN 134 Learjet introduced a digital flight deck, modified wings, and an improved interior. The Lear 55C - with SN 135 Learjet introduced Delta Fins that improve performance and handling.
LEAR 45XR (2004 to 2013 - SN 232 to SN 455)
The Lear 45XR is a Learjet 45 with a 1,000-pound heavier ramp and takeoff weights as well as two Honeywell TFE 731-20BR engines. The cockpit has a Honeywell Primus 1000 integrated avionics suite and the engines are FADEC equipped. The Learjet 45XR was certificated in 2003 and has been in production since 2004.
LEAR 45 (1996 to 2003 - SN 5 to SN 328)
The Lear 45 was the first completely new model, since the original Learjet 23. It is larger than the Learjet 31 and smaller than the 60. The cabin is seven feet longer than the 31 and has more head and shoulder room than any other aircraft in its class. The cabin has double club seating, a galley and a full aft lavatory. The cockpit has a Honeywell Primus 1000 integrated avionics suite and the FADEC equipped Honeywell TFE 731-20AR engines was developed in cooperation with Learjet for increased fuel economy and reduced operating and maintenance costs.
LEAR 40XR (2005 to 2013 - SN 2017 to SN 2133)
The Lear 40XR has a higher take-off gross weight than the basic 40. Improvements to the TFE 731-20BR engines allow for better take-off performance on hot days and at high airport elevations. Time to climb is also improved. Learjet 40 owners can upgrade to the XR through airframe and engine service bulletins.
LEAR 40 (2004 to 2009 - SN 2001 to SN 2126)
The Lear 40 is a shorter cabin version of the Learjet 45. Designed to replace the Learjet 31, the cabin is 4.5 feet longer than the 31 and has more head and shoulder room than the 31 as well. The cabin has double club seating, a galley and a full aft lavatory. The cockpit has a Honeywell Primus 1000 integrated avionics suite and the FADEC equipped Honeywell TFE 731-20 engine was developed in cooperation with Learjet for increased fuel economy and reduced operating and maintenance costs. First flight was on August 31, 2002. Deliveries began in 2004.
Lear 31A/ER has an optional extended range kit installed which adds 275 nm to the range.
LEAR 31A ( 1991 to 2003 - SN 35 to 242)
The Lear 31A has a 1,450 pound higher Ramp Weight for more payload with full fuel.
LEAR 31 (1988 to 1995 - SN 2 to SN 34)
The Lear 31 series of airplanes is essentially a Learjet 35 with a new 4-foot longer wing with almost four-foot high winglets instead of wingtip fuel tanks and large "delta fins" attached to the tail cone. These changes made the plane a much more docile one to fly, greatly improved field lengths and added 6 Kts to its normal cruise speed. Seats full range decreased to 1,225 nm plus NBAA IFR fuel reserves.
LEAR 36A (1976 to 1990 - SN 19 to SN 63)
The Lear 36 is a model 35 with the rear bench seat removed to make room for an auxiliary fuel tank holding 1,200 pounds of additional fuel. This extra fuel increased its range by 423 nm giving non-stop coast-to-coast capability when flown at long range cruise. Only 43 were delivered.
LEAR 35A (1976 to 1993 - SN 67 to SN 676)
In 1976 the Lear 35A introduced the Century III wing to reduce takeoff and approach speeds and in 1980 the Softflight wing was certified. The Lear 35A offers an NBAA IFR range of 1,930. The fuel capacity is 931 US gallons (3,524 L. Over 600 Lear 35As were built, with a production line that ended with serial number 676 in 1993.
LEAR 35 (1974 to 1976 - SN 1 to SN 66)
The Lear 35 was powered by two TFE731-2-2B engines and was 13 inches longer than its predecessor, the Model 25. First flight of the Lear 35 was on 22 August 1973, and the aircraft was FAA certified in July, 1974. It could carry up to eight passengers. The original Lear 35's went from 1974 model serial number 1 to 1976 model serial number 66. There were 66 base-model 35s built.
As of 2013, there are 41 remaining in service.
LEAR 35 / 36 AFTER MARKET MODIFICATIONS
Raisbeck Engineering offers two after-market modifications to the Learjet 35 and 36 series of aircraft. The Aft Fuselage Locker offered by this company is an external storage container mounted below the rear fuselage that can hold 300 lb of baggage. The addition of the locker imposes no performance penalties on the aircraft. This company also offers the ZR LITE performance improvement package. This modification reduces the cruise drag of the aircraft resulting in 25% less time-to-climb, 3000 to 4000 feet higher initial cruise altitude, .02+ increase in cruise Mach at equal power settings, 1% decrease in N1 and 15° ITT reduction at equal Mach and a 5-10% increase in range.
Avcon Industries also offers two after-market modifications to the Learjet 35 and 36 series of aircraft. The Avcon Fins are delta fins mounted on the aft fuselage, similar to those used on the Learjet 31 which improve directional stability when installed on Lear 35 & 36 models, and eliminate the FAA requirement for operable yaw dampers. The Avcon ER tank modifications adds 750 pounds of usable fuel in the tip tanks, which provides up to 40 minutes of additional flight time at normal cruise speeds and altitudes.
