Bombardier Learjet 40

The Learjet 40 is a light business jet produced by Bombardier Learjet. It is the successor of the Learjet 45 and was first introduced in January, 2004. The first prototype aircraft flew on August 31, 2002, and the first production aircraft had its first flight on September 5, 2002. The Learjet 40 is powered by two Honeywell TFE 731-20AR engines with 3,500 pounds of thrust. Although the overall design was inspired by the Learjet 45, its fuselage is two feet shorter and the fuel tank holds 100 gallons less than its predecessor. Its interior is, however, larger than those of its competitors, with a cabin volume of 368 cubic feet. This model's avionics include Honeywell's Primus 1000, as well as Universal UNS-1E flight management system with embedded GPS receiver. One of the jet's unique properties is that it meets FAA Part 25 requirements through its flight-control system, which is mechanically operated with integral balance tabs to reduce the risk of a burst engine rotor severing control runs.
