Learjet 40

The Learjet 40 is a light business jet produced by Bombardier Aerospace. It is derived from the Learjet 45 but has a fuselage shorter by 24.5 inches (60 cm), seats seven passengers and is powered by two Honeywell TFE731-20AR engines. It took the place of the discontinued Learjet 31A in the Learjet line, with several performance and comfort improvements taken from the Learjet 45. The prototype, a rebuilt Model 45, first flew on 31 August 2002 and the first production aircraft made its maiden flight on 5 September 2002, both from Wichita Mid-Continent Airport. The Learjet 40 entered service in January 2004, and the upgraded Learjet 40XR, introduced in October 2004, offered higher takeoff weights, faster cruise speeds and a quicker climb from TFE731-20BR engines.
