Federal Aviation Administration Certifies New Durability Kit to Boost CFM LEAP-1A Engine Longevity

The U.S. Federal Aviation Administration (FAA) and the European Union Aviation Safety Agency (EASA) have officially certified the updated high-pressure turbine (HPT) hardware durability kit for the CFM LEAP-1A engines, which power the Airbus A320neo family aircraft. Designed to improve engine performance and longevity, the kit includes the HPT stage 1 blade, HPT stage 1 nozzle, and forward inner nozzle support.

This advanced durability kit is engineered to extend time on wing, particularly in challenging hot and harsh operating environments, enhancing the reliability of the CFM LEAP-1A engines for commercial operators. With this certification, operators can expect reduced maintenance needs and increased operational efficiency, contributing to overall cost savings.

In an effort to further improve the durability of its LEAP-1A engines, CFM International has collaborated with a team of geologists to simulate the harsh environmental conditions that engines endure worldwide. By using a proprietary dust ingestion system, the company was able to replicate the wear and tear on high-pressure turbine (HPT) blades seen by operators in extreme conditions. This innovative approach allowed CFM to test, refine, and validate key improvements aimed at extending engine life and enhancing time on wing.

The CFM LEAP engine family, known for its fuel efficiency and environmental benefits, delivers a 15 to 20 percent reduction in fuel consumption and CO2 emissions compared to older engine models. Additionally, it provides a significant noise reduction, further bolstering its reputation as a sustainable and efficient choice for airlines. With over 3,500 LEAP-powered aircraft currently in service, CFM's engine has helped operators avoid more than 40 million tons of CO2 emissions. This achievement makes the LEAP engine the most successful product launch in CFM's 50-year history, with the engine reaching over 60 million flight hours in just eight years, the fastest ramp-up in the aviation industry.
