CFM and the LEAP Engine: Delivering What We Promised

June 17, 2019

More than 825 aircraft delivered to 100+ operators on five continents

LE BOURGET — 17 June 2019 – CFM International’s advanced LEAP engine continues to set a new industry standard for fuel efficiency and asset utilization as the fleet continues the most rapid buildup in commercial aviation history, with the fleet logging nearly five million engine flight hours through May, less than three years after commencing commercial service.

The first LEAP-powered commercial flight happened on August 2, 2016 on a Pegasus Airlines flight from Istanbul to Antalya. Since then, more than 825 LEAP-1A and LEAP-1B-powered aircraft have been delivered to a total of 104 operators on five continents.

“The LEAP engine just keeps delivering. The rate at which the fleet has been accumulating hours and cycles is unprecedented in the industry, but it is also achieving this with better fuel efficiency, lower noise and emissions, higher reliability, and industry-leading utilization level of 96 percent of available days flown.”

Gaël Méheust, president and CEO of CFM International

The LEAP engine has continued to build on the legacy of the CFM56 product line, which recently surpassed the one billion engine flight hour milestone. LEAP operators are seeing a 15 percent improvement in fuel consumption and CO2 emissions; lower NOx emissions; and dramatic reductions in engine noise.

All this technology is focused on providing what we promised to customers more than a decade ago: better utilization, including CFM’s legendary reliability out of the box; greater asset availability; enhanced time on wing margins to help keep maintenance costs low; and minimized maintenance actions, all supported by sophisticated analytics that enable CFM to provide tailored, predictive maintenance over the life of the product.



A 50/50 joint venture between GE Aerospace and Safran Aircraft Engines, CFM International has redefined international cooperation and helped change the course of commercial aviation since its founding in 1974. Today, CFM is the world's leading supplier of commercial aircraft engines with a product line that sets the industry standard for efficiency, reliability, durability, and optimized cost of ownership. CFM International produces the LEAP family of engines and supports LEAP and CFM56 fleets for operators worldwide. .
