Designed, developed and produced by CFM International, the CFM56 engine powers single-aisle commercial jetliners from Airbus (A320 family) and Boeing (737 family), as well as various military aircraft.
A family of engines that has addressed evolving market demand for more than 40 years.
Dispatch reliability nearly 100% and unrivaled time on wing.
Reduced operating and maintenance costs, thanks to robust design.
The world's best selling engine in aviation history
With more than 33,000 delivered to date, CFM56® engines mainly power single-aisle commercial jets from Airbus and Boeing. The CFM56®, developing 18,500 to 33,000 lb of thrust, set a standard in this market. It owes its impressive success to exceptional performance and reliability, the result of the two partners' technical excellence. The CFM56® offers dispatch reliability approaching 100%, along with unrivaled time "on-wing" (without removal for servicing) – advantages that help significantly reduce operating costs. To ensure top dispatch reliability for all customers, CFM continues to produce a volume of spare engines and parts.
The reliability and endurance of the CFM56® are just as appreciated in military applications. For example, the U.S. Air Force is CFM's leading customer, deploying more than 2,500 CFM56 engines. The British and French air forces also operate a number of CFM-powered aircraft. In particular, these engines power the KC-135 and C-135FR tankers, the E-3 and E-6 AWACS and early warning aircraft, the Boeing 737 AEW&C, C-40 transports and the P8-A Poseidon maritime patrol aircraft.
