CFM International’s new LEAP-1B turbine redesign, supported by the recently certified HPT durability kit, addresses significant operational challenges experienced within the LEAP engine family. This certification specifically targets extreme condition issues that previously impacted the engines’ performance. The HPT durability kit is designed to mitigate these problems, offering a solution for airlines operating in demanding environments. Preliminary data suggests this redesign could potentially double the time an aircraft can spend on wing under harsh conditions. CFM anticipates this upgrade will significantly enhance reliability and operational flexibility for LEAP-powered fleets worldwide.
