In December, the Federal Aviation Administration (FAA) and the European Union Aviation Safety Agency (EASA) certified the updated high-pressure turbine (HPT) hardware durability kit for the CFM LEAP-1A engines that power Airbus A320neo family aircraft. The durability kit was designed to increase time on wing, especially in hot and harsh environments, and includes the HPT stage 1 blade, HPT stage 1 nozzle, and forward inner nozzle support.

“This new hardware is fulfilling our promise to ensure that LEAP-1A engines achieve the same level of maturity, durability, and time on wing that our customers have enjoyed with the CFM56 product line,” said Gaël Méheust, President and CEO at CFM International.

To ensure that the improvements would address durability challenges in harsh environments, CFM worked with a team of geologists to engineer dust that mimicked what engines experience in these environments around the world. Using a proprietary dust ingestion system, the company was able to replicate HPT blade wear that operators were seeing in the field. The dust ingestion system allowed CFM to design, test, and validate improvements to increase the durability and time on wing of these parts.

There are currently more than 3,500 LEAP-powered aircraft in service, and the engine has surpassed 60 million flight hours after making its debut eight years ago. The engine has a 35,000-pound thrust capability, and is featured on the first Airbus A321XLR that recently entered commercial service with Iberia.
