The Garrett F109 (civilian designation TFE109) was a small turbofan engine developed in the 1980s by Garrett AIResearch for the Fairchild T-46 jet. It was designed as a new primary training engine for the United States Air Force. It used less fuel and was more reliable than previous models, and it was easier to operate. The cancellation of the T-46 program in 1986, however, ended further development of both the military and civilian versions of the engine.
