Since entering service, the LEAP-1B engine has accumulated five million engine flight hours and 1.9 million cycles.
Delta Air Lines announced that it has placed an order with CFM International for LEAP-1B engines to power its new fleet of Boeing 737 10 aircraft. The order also includes additional spare engines and an option to purchase up to 60 additional engines in the coming time. Delta was the first operator to put a CFM engine into service on April 24, 1982, with the first commercial flight of a CFM56-2-powered first McDonnell Douglas DC-8-71 aircraft between Atlanta and Savannah, Georgia.
Mahendra Nair, S.V.P. – Fleet & TechOps Supply Chain, Delta Air Lines said, “These next-generation engines offer advantages in terms of fuel efficiency, reliability, and daily utilization that are central to our ongoing effort to streamline and elevate Delta’s fleet.”
Delta Air Lines has continuously operated CFM engines since its first use in 1982. The airline currently operates more than 440 CFM-powered aircraft. CFM’s selection by Delta continues to strengthen the longstanding relationship between the two companies that spans more than 40 years.
Gaël Méheust, president and CEO of CFM International, “We are delighted to have the opportunity to bring all of the benefits of the LEAP engine to the Delta Air Lines. Our customers are seeing 15 to 20 percent better fuel efficiency, which translates to an equivalent reduction in CO2 emissions; and it has the highest reliability and daily utilization rates in this thrust class. We believe the LEAP-powered 737-10 will prove to be a real asset to Delta’s operations.”

The fleet powered by the LEAP-1B is providing 15 to 20 percent better fuel consumption and lower CO2 emissions, as well as a significant improvement in noise compared to previous generation engines. Since its entry into service in 2016, the LEAP engine allowed the operators to save more than 14 million tons of CO2.
