The LEAP engine is the culmination of cutting-edge technology and unparalleled performance.
A higher utilization of 96% means more flights and more flexibility to fly when and how you want.
Supporting 25-minute gate turnaround times, which means less time at the gate and more flying.
Delivering 15% fuel efficiency, flying with LEAP uses 66% less fuel than driving to your destination.
Flying an average of 10 hours a day and up to 11 flight cycles, every day.
Supporting longer flight legs, enabling flight options of eight hours or more.
World-class reliability and unparalleled performance, the LEAP engine delivers.

Featuring a suite of cutting-edge technologies, the LEAP sets a new standard in utilization, reliability and engine performance.
The LEAP delivers a 15% improvement in fuel consumption, compared to today’s best CFM56 engines, and maintains the same level of dispatch reliability and life-cycle maintenance costs.
Leveraging the successes and unrivaled experience of the CFM56 program, the LEAP engine is built for 99.98% dispatch reliability – which means more time in the air and less maintenance time.
Aerodynamically efficient. 3D woven. The LEAP engine’s fan blades are manufactured from 3D woven RTM (Resin Transfer Molding) carbon fiber composite, an industry first for CFM. This technology results in fan blades that are not only lightweight but so durable that each individual blade is strong enough to support the weight of a wide-body airplane like the Airbus A350 or Boeing 787.
The LEAP engine is the first engine to use additive manufacturing to “grow” complex, fully dense yet lighter engines. Its fuel nozzles are 25% lighter than previous models and five times more durable than parts manufactured conventionally.
The LEAP engine features the second generation Twin-Annular, Pre-Mixing Swirler Combustor (TAPS II). TAPS II reduces NOx emissions by 50%* versus CAEP/6 standards. Unlike traditional combustors that mix fuel and air inside the combustion chamber, the LEAP nozzle pre-mixes these elements to provide what our engineers call lean burn combustion. We just call it revolutionary.
The unique LEAP debris rejection system provides the best erosion protection, preventing sand, dirt, and other harmful items from reaching the core. As a result, the highly durable, more efficient LEAP engine stays newer for longer.
24,500 – 35,000 pounds thrust (at altitude)
23,000 – 28,000 pounds thrust
27,980 – 30,000 pounds thrust
CFM has produced and delivered the world’s largest fleet of jet engines in the single-aisle market. To continue record-high production rates for the new LEAP engine, CFM has modernized and expanded production facilities. Both GE and Safran Aircraft Engines have added new manufacturing capability at sites throughout the U.S. and France, making a combined capital investment of more than $1 billion USD.
CFM has launched its most comprehensive readiness plan ever, ensuring smooth, successful entries into service for all LEAP operators.
