The CFM LEAP family represents the engines of choice

   The CFM LEAP family represents the engines of choice for the next-generation single-aisle aircraft. The LEAP-1A is an option on the Airbus A320neo; the LEAP-1B is the exclusive powerplant for the Boeing 737 MAX; and the LEAP-1C is the sole Western powerplant for the COMAC C919. These engines had garnered more than 8,000 operates from more than 50 customers across the globe..
PROVEN

CFM and its parent companies have fielded more new engines, engine upgrades, new technologies, and have more field experience as measured in engine flight hours than anyone else. Performance and technology is better proven than promised.

BREAKTHROUGH

Performance advancements are driven by appropriate application of new technology throughout an engine. Success in development of new technology requires the combination of both consistent investment and opportunities for commercial application.

Two engine families have contributed significantly to the design of the LEAP engine, the CFM56 and the GE90/GEnx series of engines. The GE90/GEnx contributed the high-efficiency core architecture to minimize fuel consumption, while the CFM56 legacy drove reliability and maintenance cost design practices. At entry into service in 2017, it is estimated that the GE90/GEnx architecture will have generated 80 million flight hours of revenue service, while the CFM56 family will have over 700 million flight hours of experience. The LEAP engine family offers proven, material advantages over any other engine, with 550,000 hours of proven experience with 99.98% reliability, and 22,000 engines delivered on-time and on-spec.

The CFM LEAP pedigree ensures with confidence the ability to deliver a 15% improvement in fuel efficiency, as compared to the CFM56-7BE, while maintaining the same level of dispatch reliability and life-cycle maintenance costs as the CFM56-7BE. With its simple architecture and $2 billion annual investment in technology, the LEAP engine family offers the lowest cost and highest revenue-generating ability, saving an estimated nearly $3 million per plane.

This is CFM, proven performance, low execution risk, and the application of advanced technology both at entry into service and throughout an engine’s life cycle.
