The Turkish Airlines CFM deal links a new engine order with long-term maintenance support for more than 600 LEAP-1B engines. The companies signed the memorandum of understanding in Istanbul on October 16, 2026.

What the Turkish Airlines CFM Deal Covers

The official October 16 announcement separates the planned transaction into engines, fleet services and maintenance support. The purchase element covers more than 300 LEAP-1B engines, including spares.

Those engines would power 100 firm and 50 option Boeing 737 MAX aircraft announced on September 23. The agreement remains an MoU, so the companies did not disclose a final contract value or delivery schedule.

Why the 600-Engine Service Scope Matters

The long-term services portion extends beyond the newly ordered engines. It covers previously ordered and delivered units, spares, leased-aircraft engines and potential options across Turkish Airlines and AJet.

That scope creates a sizable aftermarket relationship for CFM, a joint venture between GE Aerospace and Safran Aircraft Engines. Engine servicing can generate recurring revenue long after the original aircraft delivery.

Turkish Airlines currently operates 96 Boeing 737 Next Generation aircraft and 79 Boeing 737 MAX aircraft. Investors are also monitoring Boeing’s broader delivery performance ahead of its third-quarter earnings report.

Maintenance Capacity Moves Closer to the Fleet

A separate material-services agreement would support a LEAP engine maintenance, repair and overhaul facility in Türkiye. Turkish Technic said the project would expand its engine-maintenance capabilities alongside existing aircraft and component services.

Local capacity could reduce dependence on distant repair shops as the fleet grows. It may also improve scheduling flexibility during a period of tight global engine-maintenance capacity.

The agreement follows wider investment across transport and aviation technology. Recent coverage includes Delta’s earnings and demand outlook and planned Cavorite X7 aircraft testing.
