The LEAP-1C, the first member of the LEAP® engine family, was selected by Comac (Commercial Aircraft Corporation of China) as the sole Western powerplant for its new C919 single-aisle jetliner. It offers operators exceptional technical, economic and environmental performance, with a 15% reduction in fuel consumption and CO2 emissions versus current engines, a 50% cut in NOx emissions, and compliance with the most stringent noise standards (the ICAO's Chapter 14 regulations).
CFM, in partnership with Nexcelle*, will deliver a complete integrated propulsion system (IPS) for the new Chinese jetliner, also including the nacelle and the thrust reverser.
The LEAP-1C was the first LEAP engine to begin flight testing, on a flying testbed (FTB) at Victorville, California, in September 2014.
*Nexcelle is a 50/50 joint venture between Middle River Aircraft Systems (GE) and Aircelle (Safran)
