History

Learjet introduced the Model 31 in 1987 to offer operators a cost-effective light jet with enhanced aerodynamics. The 31A variant with increased performance followed in 1990. The type has been operated by business aviation customers, charter operators, and fractional ownership programs worldwide.

Variants

The Learjet 31A with improved TFE731-2-3B engines was the main production variant; later 31A/ER added extended range capability.

Where you'll see it

Worldwide operation by business aviation customers; no military service of note. Canada is listed as country of manufacture rather than origin as Learjet was headquartered in Wichita, Kansas.
