    The nacelles of the LEAP-1C engines on the C919, the new Chinese medium-haul aircraft, were designed, developed and manufactured by Nexcelle, a 50/50 joint venture owned by Safran Nacelles and Middle River Aircraft Systems (a division of GE Aviation). Safran (Safran Nacelles) also provides the aircraft's Electrical Thrust Reverser Actuation System (ETRAS). This thrust reverser replaces the heavier hydraulic systems.
