GE Aerospace Signs Multi-Year Deal with China Airlines for GE9X Engine Maintenance

GE Aerospace has signed a multi-year service agreement with China Airlines for the maintenance, repair, and overhaul of GE9X engines for the airline's 14 new Boeing 777X aircraft. The Taiwan-based carrier has been a GE Aerospace customer since 1999. GE9X is the world's most powerful commercial aircraft engine and offers 10% better fuel efficiency than its predecessor.

CINCINNATI - July 2, 2025 - GE Aerospace (NYSE:GE) has announced a multi-year service agreement with China Airlines to cover the maintenance, repair, and overhaul (MRO) of GE9X engines for the airline's 14 new Boeing 777X aircraft. This agreement, which is effective immediately, underscores the long-standing relationship between GE Aerospace and China Airlines, which has been a GE Aerospace customer since 1999 [1].

China Airlines, a leading Taiwan-based carrier, has been a consistent customer of GE Aerospace, with service agreements in place for GE90 and GEnx engines for its B777-300ER and B787 fleet. The addition of the GE9X engines, the world's most powerful commercial aircraft engine, to its fleet further solidifies the partnership [1].

The GE9X engine, which powers the Boeing 777X family of aircraft, offers a 10% improvement in specific fuel consumption compared to its predecessor, the GE90-115B, and features emissions that are a generation ahead in technology. This makes it one of the most fuel-efficient engines in its class [1].

Russell Stokes, President and CEO of Commercial Engines and Services at GE Aerospace, expressed gratitude for China Airlines' trust in GE Aerospace's products and services. "We are grateful that China Airlines selected GE Aerospace to service its new GE9X engines and for continuing to place their trust in our products and services," he said. "We will continue to work closely with them to support the GE9X's entry into service and smooth operation of their 777X fleet" [1].

The GE9X engine, which has a diameter of 161 inches, is capable of generating up to 110,000 lbf of thrust. Its advanced materials and high bypass ratio contribute to its fuel efficiency, making it a key component in the Boeing 777X's sustainability efforts [2].

The Boeing 777X, which includes variants 777-8 and 777-9, is expected to enter commercial service in 2026, six years behind schedule due to various setbacks. Despite the delays, the aircraft is anticipated to replace older 777 models and provide a fuel-efficient, high-capacity option for airlines [2].

China Airlines, with a fleet of 113 aircraft, is one of the largest operators of the Boeing 777X, currently having 14 new aircraft on order. The airline's commitment to environmental protection and sustainability aligns well with GE Aerospace's focus on fuel efficiency and emissions reduction [1].
