The Learjet 45 is a mid-sized business jet aircraft introduced in January 1998. The cockpit is equipped with a four-screen Electronic Flight Instrument System avionics system. The aircraft is powered by two 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. The LJ45 is a member of the Bombardier Learjet Family.

Accidents & Serious Incidents involving LJ45

  • B737/LJ45, Chicago Midway, USA 2011 (On 1 December 2011 a Southwest Boeing 737-700 was cleared to taxi in after landing on a route which included crossing another active runway before contacting GND and the controller who had issued that clearance then inadvertently issued a take off clearance to a Gama Charters Learjet 45 for the runway to be crossed. One of the 737 pilots saw the approaching Learjet and warned the PF to stop as the runway crossing was about to begin. The departing aircraft then overflew the stationary 737 by 62 feet after rotating shortly before the crossing point without seeing it.)
