ST Engineering Signs Multi-Year Agreement with Xiamen Airlines for CFM LEAP-1A PRSV Service

ST Engineering Secures Multi-Year MRO Agreement with Xiamen Airlines for CFM LEAP-1A Engines
Singapore, 4 February 2026 – ST Engineering has formalized a multi-year maintenance, repair, and overhaul (MRO) agreement with Xiamen Airlines to provide Performance Restoration Shop Visit (PRSV) services for the airline’s fleet of CFM LEAP-1A engines. This partnership extends a longstanding relationship of over 35 years, during which ST Engineering has supported Xiamen Airlines with engine services for models including the JT8D, CFM56-3, and CFM56-7B.
Strategic Partnership Amid Fleet Modernization
The agreement represents a pivotal development as Xiamen Airlines continues to modernize its fleet with next-generation aircraft powered by LEAP-1A engines. Tang Jianqi, Deputy General Manager of Engineering & Maintenance at Xiamen Airlines, emphasized the significance of the deal, noting that ST Engineering’s success in securing this competitive contract reflects its comprehensive expertise in engine maintenance, encompassing quality, service, and pricing. He underscored that engine overhaul strategy remains a critical decision within Engineering & Maintenance, and a stable, long-term partnership with a capable overhaul provider like ST Engineering aligns with the airline’s strategic objectives.
Tay Eng Guan, Head of Engine Services at ST Engineering, highlighted that the renewed agreement affirms Xiamen Airlines’ confidence in the company’s MRO capabilities, which are grounded in a proven history of reliable and high-quality maintenance. He added that by enhancing support for CFM LEAP engine PRSV services, ST Engineering aims to enable Xiamen Airlines to focus on operational growth while ensuring optimal engine performance and upkeep.
Expanding Capabilities Amidst Competitive Market Dynamics
As Asia’s first Premier MRO provider for CFM LEAP engines, ST Engineering has developed advanced testing capabilities for both LEAP-1A and LEAP-1B variants. The company is actively preparing to expand its PRSV and full overhaul services to address increasing market demand. However, ST Engineering faces challenges in maintaining competitive pricing against other third-party MRO providers, ensuring consistent quality and reliability, and managing potential supply chain constraints in an increasingly contested aftermarket.
The competitive landscape for CFM engine maintenance is expected to intensify, particularly following the renewed agreement between CFM International and the International Air Transport Association (IATA) to promote aftermarket competition through 2033. Industry players such as GA Telesis Engine Services are also expanding their CFM LEAP engine offerings, underscoring the dynamic nature of the MRO sector.
ST Engineering is currently showcasing its comprehensive MRO solutions, multidisciplinary capabilities, and technological leadership at the Singapore Airshow, held from 3 to 8 February 2026 at the ST Engineering Pavilion (G01).
CFM LEAP engines are manufactured by CFM International, a 50-50 joint venture between GE Aerospace and Safran Aircraft Engines.
