About the Learjet 40
Type certificated 2003
Overview
The Learjet 40 entered service in 2004 as the shorter, lighter member of the Learjet 45 family and the successor to the Learjet 31A. It is a Model 45 with roughly two feet removed from the fuselage and about 100 gallons less fuel, sharing the same flat-floor cross-section, Honeywell TFE731-20AR engines rated 3,500 lbf each, and FAR Part 25 transport-category certification. The uprated 40XR added thrust margin for hot-and-high fields; both carry the Pro Line avionics that the later G5000-equipped Learjet 70 would replace.
The 40 suits a buyer who values Learjet speed and a 51,000-foot ceiling over cabin space and is willing to fly the smallest, least expensive airframe in the family to get the lowest entry price. It seats one fewer than the Learjet 45 and carries about 100 gallons less fuel, so range runs near 1,700 nm and the cabin tightens with a full load. The honest competition is the single-pilot light jets: a Cessna Citation CJ4 or Citation Encore will fly the same missions more cheaply and without a second required crew member, and the 40 earns its keep only for an owner who specifically wants the altitude, the cruise speed, and the Learjet badge.
Key Features for GA Buyers
- High-altitude capability. A 51,000-foot service ceiling and Mach 0.81 cruise let the Lear 40 fly above most commercial traffic and weather.
- Cabin comfort. The flat-floor cabin with no spar intrusion offers a cross-section larger than many light-jet competitors, putting mid-size comfort in the light-jet bracket.
- Part 25 safety. Built to FAR Part 25 transport-category standards, including redundant systems not always found at this weight class.
Trade-offs
- Range vs. payload. While capable of approximately 1,700 nm, filling the seats significantly reduces range. The Lear 40 carries about 100 gallons less fuel than the Lear 45.
- Climb performance. Initial climb rate of approximately 2,800 fpm is modest compared to the legacy Learjet 35 and 20-series figures, primarily due to the heavier, robust airframe.
- Two-pilot certification. Like the rest of the Learjet line, the 40 is type-certificated for two pilots, so owner-operator budgets must carry a second crew member or a contract pilot, a real cost difference against the single-pilot light jets it competes with.
