Air France Industries KLM Engineering & Maintenance (AFI KLM E&M) and SunExpress have signed a new, long-term agreement for the maintenance of CFM56-7B engines.

The contract marks a new chapter in the partnership between the two companies and will span from 2025 through 2031.

Under the terms of the agreement, AFI KLM E&M will provide comprehensive shop visit support services for the CFM56-7Bs powering SunExpress’ fleet of Boeing 737 Next Generation aircraft.

The airline has ambitious expansion plans, with its fleet projected to grow to 166 aircraft by 2035.

Cemil Sayar, chief operations officer of SunExpress, said: ” As our fleet continues to grow, it is critical to work with partners who understand our evolving operational needs.

“Through our partnership, AFI KLM E&M has consistently demonstrated technical expertise and flexibility we value, and we are pleased to extend our ongoing collaboration.”

Martijn de Vries, vice president at KLM Engine Services, said: “We are honoured to renew and strengthen our partnership with SunExpress. We are committed to delivering efficient, and high-performance engine solutions that support SunExpress in maintaining its excellent operational standards.

“The potential to expand this relationship into LEAP-1B support further reflects the trust and confidence between our teams.”
