The Bombardier Learjet 31 is a light business jet introduced as part of Learjet’s ongoing evolution of performance and design. First produced in 1983, with production continuing through 1995, the Learjet 31 combined the fuselage of the Learjet 35/36 with the wing design of the Learjet 55, resulting in an aircraft that offered both excellent speed and improved handling characteristics. During its production run, the Learjet 31 established itself as one of the fastest and most efficient light jets of its generation.
The Learjet 31 is powered by two Honeywell TFE731-2 turbofan engines, each producing 3,500 pounds of thrust. With a maximum takeoff weight (MTOW) of 15,500 pounds and a balanced field length of approximately 3,700 feet, the aircraft delivers strong takeoff performance and reliability for operators. The combination of high thrust-to-weight ratio and aerodynamic wing refinements allowed the Learjet 31 to achieve higher cruise speeds while maintaining efficiency.
The cabin of the Learjet 31 accommodates up to seven passengers in a typical executive configuration. While compact compared to larger business jets, the interior was designed to maximize comfort within the light jet category. Noise reduction, upgraded insulation, and a refined layout made the cabin experience more comfortable than earlier Learjet designs, supporting its appeal for short to mid-range corporate travel.
The Learjet 31 became well-regarded for its speed, climb performance, and agility, with a reputation as one of the most “pilot-friendly” aircraft in the Learjet family. Though later succeeded by updated variants such as the Learjet 31A, the model played a pivotal role in advancing Learjet’s position in the competitive light jet market. It remains recognized as a classic example of Learjet engineering, balancing performance, efficiency, and reliability.
