Bombardier Learjet 40XR Specs and Description

Background/History

In an effort to place a competitive product in the growing light jet market, Bombardier announced the Lear 40 in July 2002 at the Farnborough Air Show.The entry level Model 40 replaced the 31A and brings with it best-in-class cabin volume and performance for a marginal price increase of $170,000 over that of the 31A. As for preformance, the Model 40 is the only light jet that can fly nearly 450 KTAS coast-to-coast against strong winter headwinds with only one fuel stop. Based upon the model 45, the 40 is about two feet shorter in cabin length featuring six seats, instead of eight. In 2004 Bombardier announced the Lear 40XR with a preliminary service entry date of 2006. The new 40XR is a more powerful derivative of the already active Lear 40. Some basic improvements of the 40XR are in the areas of hot-and-high performance, faster time-to-climb speeds, as well as faster ETEs. These improvements were made possible by the incorporation of Honeywell’s TFE731-20-BR engines. To date there have been 92 aircraft produced.

Power

The Learjet 40XR is powered by a pair of Honeywell TFE731-20-BR turbofans rated at 3,500 lbs. thrust each. The overhaul interval for these engines is 5,000 hours.

Avionics

The Learjet 40XR is equipped with the Honeywell Primus 1000 avionics system, with four DU870 large format EFIS displays, EICAS, TCAS 2000, Honeywell Primus 660 color weather radar, EGPWS with Windshear Alert, and dual Primus II nav/comms.

Design Features

The Learjet 40XR is a conventional aluminum semi-monocoque design. The familiar Learjet delta fins adorn the lower section of the swept T-tail. The slightly-swept semi-super critical wing was a clean-sheet design from the 45 and employs drag-reducing winglets. Like the wing, the fuselage was an all-new design from the 45, but two feet less in cabin length. The retractable tricycle landing gear has dual wheels on each of the main units and a single nosewheel, with a long-travel, trailing-link main gear.

Accomodations

The Learjet 40XR is ordinarily configured for six passengers in a club plus two arrangement. The Model 40XR features an external baggage compartment, with 50 cu.ft. of space, forward coat closet in the refreshment center, and a small storage compartment opposite the lav.
