The Commercial Aircraft Corporation of China (Comac) has reportedly selected CFM International's LEAP-X engine to power its new 150-200 seat C919 jet.

Leeham Co., a consultancy run by aerospace analyst Scott Hamilton, says the Chinese aircraft maker has selected the LEAP-X to power the new narrowbody, citing two unnamed sources.

"We have no comment. We'll know when Comac makes its announcement, which they have not done," says CFM.

The LEAP-X engine, which could be certified by 2016, has yet to find a launch customer. The engine touts a 16% improvement in fuel burn over the current CFM56 engines and features an eight-stage compressor, the Twin Annular Pre-Swirl (TAPS II) combustor and single-stage high-pressure turbine.

The Comac C919 is designed to compete with the Airbus A320 and Boeing 737.
