18,500 - 27,300 POUNDS THRUST

Engine Overview

The CFM56-7B is the exclusive engine for the Boeing Next-Generation single-aisle airliner (737-600/-700/-800/-900/-900ER/BBJ). Military customers around the world are taking advantage of the benefits of CFM56-7B-powered 737 military variants: the C-40 Clipper military transport, the P-8 Poseidon anti-submarine aircraft, and the Boeing 737 AEW&C reconnaissance aircraft.

In total, nearly 7,000 CFM56-7B engines are in service on 737 aircraft, making it the most popular engine/aircraft combination in commercial aviation. More than 180 customers fly CFM56-7B engines and the fleet has accumulated more than 105 million flight hours. The primary factors behind the engine's broad-based acceptance include industry-leading reliability and environmental friendliness, low cost of ownership and world-class customer support.

All CFM56-7B engines delivered since mid-2007 are in the Tech Insertion configuration, making them compliant with CAEP/6 environmental requirements. Looking to the future, CFM is testing yet another enhancement to the engine – the CFM56-7BE. Poised for mid-2011 entry into service, this next production standard will provide a 2 percent reduction in fuel burn and carbon emissions when coupled with the improved Next-Generation 737.
