Learjet 40 (LJ40) is a light business jet produced by Bombardier Aerospace.
The Learjet 40 originated from the Learjet 45, but has a shorter fuselage (by 24.5 inches/60 cm), and is powered by two Honeywell TFE731-20AR engines. These are known as the "AR" engines. The 40 model replaces the discontinued light Learjet 31a in the Learjet model line, with a number of performance and comfort improvements taken from the 45 model.
The prototype aircraft, a rebuilt Model 45, had its maiden flight on August 31, 2002, and the first production aircraft had its first flight on September 5, 2002. Both flights took off from the Wichita Mid-Continent Airport. The LJ40 entered into service in January, 2004.
The Learjet 40XR is an upgraded version introduced in October, 2004, offering increased takeoff weights, faster cruise speeds and faster time-to-climb rates as compared to the LJ40. The improvements are due to the upgrading of the engines to the TFE731-20BR configuration. These are the "BR" engines. LJ40 owners can upgrade their aircraft through the incorporation of several service bulletins.
