Summary: This was Garrett's first turboprop engine, and a key first-generation turbine engine that significantly improved performance and utility of general aviation, executive and commercial commuter aircraft. From a technical perspective, it was noteworthy for its short and compact configuration, low installed weight and drag, good specific fuel consumption, aerodynamic efficiency, and performance.; In 1964, the company's YT76 turboprop version of the TSE331 generator set was selected for the North American OV-10A counter insurgency aircraft, and entered Viet Nam War service in 1968.; Garrett simultaneously developed a commercial version of the engine, for which the launch customer was the Mitsubishi MU-2 transport. Over time a number of more powerful TPE331 models were developed for general aviation aircraft such as the Beech B100 King Air, Cessna Conquest 441, Commander Series, Piper Cheyenne IV, and Mitsubishi Solitaire/Marquise. Commuter aircraft applications included the Fairchild Merlin and Metro, BAe Jetstream 31 and Super 31, CASA 212, and Shorts Skyvan 3.
