Spanning a thrust range of 18,500 to 34,000 pounds. CFM engines are the power behind more than 8,000 commercial and military aircraft.

CFM's vast field experience of more than 625 million flight hours is built into every engine we make. Blending proven reliability with cost-effective technology, CFM engines lead the industry in reliability, durability, performance retention, and time on wing.




The CFM LEAP-1B will be the exclusive powerplant for the Boeing 737 MAX family of single-aisle aircraft (737 MAX-7, 737 MAX-8, 737 MAX-9).



The CFM56-7B is the exclusive engine for the Boeing Next-Generation single-aisle airliner (737-600/-700/-800/-900/-900ER/BBJ).

Your requirements as a corporate jet operator are demanding. You need an aircraft that can take you wherever you want, whenever you want, so you can carry out your business without delay or restriction.

In a nutshell, you want total operational freedom with the most dependable engine available.

No other engine manufacturer can offer you a product quite like the CFM56 engine, with its reliability, environmental benefit and investor appeal. When it’s powering your corporate jet, you’ll enjoy total peace of mind.

Executive operators demonstrate their confidence in CFM56 by making it the engine of choice for the A318 Elite and A319 Corporate Jet. In 2005 and 2006, 35 out of the 36 new A318 Elite and A319 Corporate Jet owners chose to power their aircraft with CFM56-5B rather than an alternative engine. The CFM56-7B is the sole power for the Boeing Business Jets (BBJ) series.

Governments around the world also know the secret of our engine. The Czech Republic, France, Italy and Thailand chose CFM to transport their VIPs.
