Iran Aircraft Industries(IACI) or SAHA (صها abbreviated of صنایع هواپیمایی ایران) was established in 1961 mainly for major repair of fighter, passenger, and air support planes. Over time, SAHA became an important part of Iran’s aviation industry. In 1998, Iranian scientists and experts started designing, engineering, and manufacturing complex engine parts, airplane parts, and manufacturing turbine engines like Toloue-4.
SAHA is currently working on turbo prop engines called TV-3 for IrAn-140 planes.
