Turkish Airlines has signed a strategic agreement with CFM International to strengthen engine maintenance capabilities and support the expansion of its Boeing 737 MAX fleet.
The long-term services agreement will cover the airline group's entire LEAP-1B engine fleet, including engines already ordered and delivered, spare engines, units installed on leased aircraft and potential future options. The combined total exceeds 600 engines operated by Turkish Airlines and its subsidiary, AJet.
The memorandum of understanding (MoU) was signed during a ceremony in Istanbul by Turkish Airlines Chairman of the Board and the Executive Committee, Prof. Murat Şeker; Turkish Technic CEO and Board Member, Mikail Akbulut; and Safran CEO Olivier Andriès. Safran is one of the two parent companies of CFM International.
The agreement also includes a material services arrangement to support the development of an engine maintenance, repair and overhaul (MRO) facility in Türkiye.
Şeker said the partnership would help Turkish Airlines accommodate fleet and network growth while improving operational efficiency. He added that the expanded services agreement would provide the technical expertise and long-term support required to develop LEAP engine maintenance capabilities.
Akbulut said the agreement would enable Turkish Technic to undertake comprehensive LEAP engine maintenance. He also reaffirmed the company's commitment to investing in engine services alongside its existing aircraft and component maintenance operations.
Andriès described the MoU as another milestone in a relationship with Turkish Airlines that has lasted nearly four decades. He said the agreement reflected both companies' ambitions to support the airline's growth and fleet expansion, while promoting an open MRO ecosystem offering flexible, competitive services to improve operational performance and control costs.
GE Aerospace Chairman and CEO H. Lawrence Culp Jr. also welcomed the agreement, highlighting Turkish Airlines' extensive international network and its confidence in CFM engines. He said the partnership would build on the companies' established relationship as the airline expands its Istanbul operations and engine maintenance capabilities.
Turkish Airlines currently operates 96 Boeing 737 Next Generation aircraft powered by CFM56-7B engines and 79 Boeing 737 MAX aircraft equipped with LEAP-1B engines.
CFM said it had delivered more than 10,000 LEAP engines during the 10 years since the engine entered service, with the fleet accumulating over 100 million flight hours. The manufacturer continues to introduce upgrades, including a high-pressure turbine durability kit designed to extend time on wing and a reverse bleed system (RBS).
The agreement is expected to strengthen Turkish Airlines' long-standing relationship with CFM International and support the integration of newly ordered Boeing 737 MAX aircraft into its expanding fleet. The planned engine MRO facility will also enhance Turkish Technic's ability to provide comprehensive maintenance services.
