|Gama Aviation Learjet 45 at Farnborough, England in July 2006|
|National origin||Canada and United States|
|First flight||7 October 1995|
|Developed into||Learjet 70/75|
The development of the LJ45 was announced by Bombardier in September, 1992, and first flight of the prototype aircraft took place on October 7, 1995, the 32nd anniversary of the first flight of the Learjet 23. FAA certification was delayed, and finally granted in September 1997, with the first customer aircraft subsequently delivered in January, 1998. The cockpit is equipped with a four-screen Honeywell Primus 1000 EFIS avionics system. The aircraft is powered by two DEEC-controlled Honeywell TFE731-20 engines, a version developed specifically for this airframe. An internal APU provides ground power.
The Learjet 45XR is an upgraded version introduced in June, 2004, offering higher takeoff weights, faster cruise speeds and faster time-to-climb rates as compared to the LJ45. The increases are due to the upgrading of the engines to the TFE731-20BR configuration. LJ45 owners can upgrade their aircraft through the incorporation of several service bulletins.
In size, the LJ45 and LJ45XR fit between the smaller Learjet 31 and Learjet 40 and the larger Learjet 60 in the Lear product line. It has a 1,971-nautical-mile (3,650 km; 2,268 mi) range at Mach 0.81 with four passengers on board. De Havilland Canada builds the LJ45s wings, and Bombardier subsidiary Short Brothers of Belfast, Northern Ireland, builds the fuselage and empennage.
Accident and Incidents
- 2008 Mexico City plane crash; On 4 November 2008, Mexican Interior Minister Juan Camilo Mouriño, Assistant Attorney General José Luis Santiago Vasconcelos and 7 others were killed in an accident involving a Learjet 45XR. The aircraft crashed on a busy road, killing another 7 people on the ground. Investigators determined that the pilots had been flying too close to a 767 and lost control after flying into the larger plane's wake turbulence.
