Overview
Program history
The Model 40 was developed from the Learjet 45 platform to address a different capacity and acquisition-cost point in the light-jet market. It remained part of the same certified Model 45 family rather than a wholly separate type. The later 40XR improved the performance offering, and the Learjet 70 subsequently renewed this smaller member of the range.
