The CFM56 owes its success to
its exceptional performance and reliability, built on the proven technological excellence of GE
and Safran Aircraft Engines.
With dispatch reliability of close to 100% and unrivalled time on wing helping to drive down the cost of ownership, the engine now powers aircraft for more than 570 operators worldwide.
The CFM56 has set the standard for single-aisle commercial jet engines. With more than 31,000* engines delivered, the CFM56 is the best-selling product line in commercial aviation history. It powers the single-aisle jetliners from the world’s leading plane makers, Airbus and Boeing.
A 50/50 JOINT COMPANY BETWEEN GE AND SAFRAN AIRCRAFT ENGINES, DEVELOPS, PRODUCES, AND MARKETS CFM56 ENGINES, WHICH NOW POWER MORE THAN 13,400 SINGLE-AISLE COMMERCIAL AND MILITARY JETLINERS WORLDWIDE.

CFM56-5B
GE designs and develops the engine’s core, comprising the high-pressure compressor and turbine and the combustor. Safran Aircraft Engines designs and builds the fan, the low-pressure compr essor and turbine, and the accessory gearbox.
CFM has designed, tested, certifed, produced, and supported the largest fleet of commercial jet engines in the single-aisle market over the
past 40 years. This achievement is anchored in the development and continuous improvement of world-class facilities on both sides of the Atlantic, with each partner responsible for half
the workload.
