The Bombardier Learjet 31A is an upgraded variant of the Learjet 31, developed to enhance performance and avionics for the light jet segment. Production began in 1991 and continued through 2003, replacing the original Learjet 31 as the primary version in service. Building on the proven fuselage of the Learjet 35/36 and the efficient wing design of the Learjet 55, the 31A delivered improved systems integration and reliability, solidifying its position within the Learjet family.
Powered by two Honeywell TFE731-2 engines, each producing 3,500 pounds of thrust, the Learjet 31A offers a maximum takeoff weight (MTOW) of 15,500 pounds and a balanced field length of approximately 3,800 feet. These performance figures, combined with a service ceiling of 51,000 feet, provided operators with excellent climb capability and operational flexibility.
The cabin of the Learjet 31A typically accommodates up to seven passengers in a business configuration, excluding crew. Bombardier incorporated cabin refinements such as improved soundproofing, redesigned sidewalls, and upgraded seating arrangements to enhance passenger comfort on short- to medium-range missions.
With its upgraded avionics suite, including digital systems that improved situational awareness and pilot workload, the Learjet 31A remained a competitive option in the light jet category throughout its production run. Its combination of performance, efficiency, and enhanced systems has ensured continued use among corporate operators and charter fleets worldwide.
