LEAP Engine Fleet Surpasses Ten Million Flight Hours

May 5, 2021

• ~1,400 LEAP-powered aircraft delivered to date
• LEAP engines provide 15% lower fuel consumption, CO2 emissions

WEST CHESTER, Ohio – CFM International’s LEAP engine continues to set the industry standards as the fleet achieves one of the most rapid accumulation of hours and cycles in commercial aviation history. The LEAP fleet has surpassed 10 million engine flight hours and five million flight cycles in less than five years of commercial service.

Since the first LEAP-powered flight entered commercial service in August 2016, the engine program has grown exponentially. Nearly 1,400 LEAP-powered aircraft have been delivered to some 136 operators on five continents to date.

The LEAP engine just keeps delivering what we promised more than ten years ago when we launched the program. The rate at which the fleet has been accumulating hours and cycles is fantastic.

We’re honored to continue to reliably power our global operators’ fleets, with a shared vision and ambition to create lower emissions and reduced noise to deliver the most efficient flight operations possible.”

Gaël Méheust, president and CEO of CFM International

CFM is actively working to deliver on its clear ambition to build a more sustainable future, leading with the LEAP engine, which is providing operators a 15 percent improvement in fuel consumption and CO2 emissions compared to previous generation engines, along with dramatic reductions in noise emissions. All this technology is focused on providing higher utilization, including CFM’s historical reliability, greater asset availability, enhanced time on wing 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.

The LEAP engine is a product of CFM International, a 50/50 joint company between GE and Safran Aircraft Engines. This engine has experienced the fastest order ramp up in commercial aviation history and CFM has delivered approximately 2,800 installed LEAP engines already to a total of 136 operators worldwide.
