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.
