CFM faces some uncertainties surrounding its Leap-1C turbofans for the Comac C919 narrowbody, although the engine program schedule calls for that variant of the three-member Leap family to go to test first.

CFM International has expanded its TruEngine program coverage to include content assurance guarantee (CAG) for subsequent buyers of qualified CFM56 engines. The engine maker launched the CAG in response to customer requests for more assurance of asset value upon the sale of a qualified CFM56. With this guarantee, customers who purchase a qualified CFM56 are entitled to a 50-percent credit on replacement parts if, at the first shop visit after transfer of ownership, any parts or repairs found in the engine are not original CFM parts or CFM-authorized repairs.
Boeing and China’s Comac opened a new joint-venture facility in Beijing last week to study biofuels refinement and improvements to air traffic management. Its first project is to study the prospects for refining used cooking oil, often described in China as “gutter oil,” into sustainable aviation biofuel.
Major orders for the new CFM International Leap-X turbofan engine are due to be announced during the first four days of the Paris show, intensifying the battle with Pratt & Whitney to power the Airbus A320neo. “We’re set for this to be one of our best shows ever,” said the company.
Engine maker CFM has chosen sides in the debate between proponents and opponents to composite materials on turbofan moving parts by introducing fibers woven in three dimensions for fan and even low-pressure turbine (LPT) blades. The bet on this next-generation composite manifests itself on the Snecma-General Electric venture's Leap-X “advanced turbofan” program.
