In addition, the company improved engine durability and reduced parts count to achieve lower maintenance costs. When combined with airplane improvements, the engine provides two percent better fuel efficiency and up to four percent lower maintenance costs. The foundation of the LEAP engine is heavily rooted in advanced aerodynamics, environmental, and materials technology development programs.
