CFMI CFM56

The CFM International CFM56 series is a family of high-bypass turbofan aircraft engines made by CFM International (CFMI), with a thrust range of 18,000 to 34,000 pounds-force. CFMI is a 50–50 joint-owned company of SNECMA, France and GE Aviation (GE), USA. Both companies are responsible for producing components and each has its own final assembly line. GE produces the high-pressure compressor, combustor, and high-pressure turbine, and SNECMA manufactures the fan, gearbox, exhaust and the low-pressure turbine, while some components are made by Avio of Italy. The engines are assembled by GE in Evendale, Ohio, and by SNECMA in Villaroche, France. By January 2010, the CFM56 had flown more than 470 million cumulative hours.
