The world’s best-selling jet engine.


The CFM56 engine set the industry standard for single-aisle commercial jet engines that holds today. Owing its success to its exceptional reliability and performance, CFM56 was built on over four decades of experience and technological excellence. With more than 33,000 engines delivered to date, it powers more than 600 operators worldwide.

More than 1 billion of flight hours.


Customer needs propel CFM’s technology investments. When new technologies mature, CFM incorporates the advances into production standards and re-invigorate the fleet already flying through upgrade kits. In 2007, Tech Insertion became the production configuration for the CFM56-5B PIP and the CFM56-7BE engines as of 2011, further providing operators with significant improvements in fuel consumption, emissions levels, and maintenance costs.


Powering the Airbus A320ceo family

The CFM56-5B is the engine of choice for the A320ceo family, having been selected to power nearly 60 percent of the aircraft ordered. Today, it is the only engine that can power every model of the A320ceo family with one bill of materials. The engine’s broad-based market acceptance has been because of its simple, rugged architecture, which gives it the highest reliability, durability, reparability and the lowest cost of ownership in its class.

The CFM56 fleet continues to fly significantly with 23,000 engines still in service. Our mission is to keep this fleet flying and support the 600+ operators around the world through the CFM56 open MRO network. With over 45% of the fleet which has not yet carried out its first shop visit, we will reach the peak of shop visits in the coming years. GE Aerospace and Safran Aircraft Engines continue to invest in the development of repairs and production of spare engine and parts, support the development of the global MRO capacity as well as a comprehensive lifespan support.
