10_0372_ernoult585770_1200x578_a320_cfm56_5.jpg

CFM International, a 50/50 joint company between Safran Aircraft Engines and GE, develops, produces and markets CFM56® engines, which now power some 13,400 single-aisle commercial jetliners worldwide. Renowned for its unparalleled reliability and low cost of ownership, the CFM56 is the best-selling engine in the history of aviation.

CFM56-7B: the exclusive Boeing 737NG engine

Selected by Boeing as the sole-source powerplant for its Next-Generation 737 range, the CFM56-7B develops 19,500 to 27,300 pounds of thrust. Thanks to upgrades to the core and low-pressure turbine, the latest CFM56-7BE configuration delivers significant performance improvements for operators, including a 1% reduction in fuel consumption and a 4% cut in maintenance costs, as well as extended part lifetimes. The CFM56-7BE is fully interchangeable with other CFM56-7B engines and modules, and upgrade kits can be easily fitted to the CFM56-7B and CFM56-7B/3, providing maximum flexibility for operators.
