The AlliedSignal TFE731 was largely responsible for the broad-scale introduction of medium-size corporate fanjet aircraft, a trend that began in the early 1970s. The engine's low specific fuel consumption greatly increased the range of corporate jet aircraft. The TFE731 is used on many types of business jets, including Bombardier Learjets, Dassault Falcons, Cessna Citations, Raytheon Hawker 800s, and Israel Aircraft Industries 1125 Astras.
As one of the first development engines for the TFE731-3 engine series, this engine has been rebuilt nearly 200 times for various development and certification testing programs. It has undergone more than 2,000 hours of hard testing in the manufacturer's test cell facilities in Phoenix, Arizona, and on a Falcon 20 jet aircraft. This testing resulted in many improvements to the TFE731 series, including the development of a low-smoke combustion system and enhanced engine controls.
