CFM and ST Engineering sign service agreement to expand LEAP open MRO network


  • ST Engineering is first MRO provider in Asia to offer full range of LEAP- 1A, LEAP-1B Services


WEST CHESTER, Ohio – 22 March 2023 CFM International and ST Engineering’s Commercial Aerospace business have signed a CFM Branded Service Agreement (CBSA) for LEAP-1A and LEAP-1B engines. Under the terms of the CBSA, ST Engineering will provide the full scope of LEAP Maintenance, Repair & Overhaul (MRO) services for operators worldwide.


ST Engineering is the first provider in Asia to join the LEAP MRO network under a CBSA agreement. Comprehensive MRO services will be provided at their facility in Singapore.

ST Engineering has been a LEAP MRO network provider since 2020, providing quick turns for the LEAP-1A and LEAP-1B engines. The company will also add this year test cell capabilities for LEAP-1B engines. This CBSA agreement further expands their scope to provide a full range of maintenance solutions for LEAP engines to the highest standards. CBSA license holders are provided the highest level of CFM support and training, as well as expanded access to proprietary overhaul and repair technology as they work with CFM customers globally to provide comprehensive maintenance solutions.

“CFM is excited that ST Engineering is expanding its role within the LEAP MRO network as a CBSA provider," said Tom Levin, VP of CFM Commercial Programs for CFM parent company GE Aerospace. “They have significant experience in the CFM56 network and have already developed experience providing services for LEAP engines. This addition to the LEAP MRO network will further strengthen the support of our CFM customers.”

“We are pleased to further strengthen the longstanding relationship that we have with CFM International through this new license agreement,” said Jeffrey Lam, Commercial Aerospace President at ST Engineering. “With the new LEAP partnership, ST Engineering will now have an enhanced portfolio of engine MRO solutions that allows us to serve customers who transition into new-generation aircraft, as we continue in our comprehensive and dedicated support for their CFM56 engine needs. As one of a small number of CBSA providers, ST Engineering will be able to offer deep and broad LEAP OEM service solutions to drive down maintenance lifecycle costs, and provide fully-integrated overhaul and parts repair services for LEAP engines to our customers.”

“This CBSA agreement will enable ST Engineering to expand its LEAP capabilities within the CFM MRO global network”, said Nicolas Potier, VP Support & Services for CFM Parent company Safran Aircraft Engines. ”Their longstanding experience with CFM engines is a real asset for our airline customers as the LEAP fleet is growing fast. ST engineering will be a key player in our ambition to continue offering world-class support to our customers.”

Given the commercial success of the LEAP engine family that entered into commercial service in 2016, demand for LEAP MRO services will grow rapidly in the coming years.  More than 5,000 LEAP engines have been delivered to customers worldwide, with more than 10,000 engines still in the backlog. 

The advanced CFM LEAP engine continues to set industry standards for fuel efficiency and asset utilization, and has accumulated more than 29 million engine flight hours and over 13 million cycles in commercial operation. The fleet is providing up to 20 percent better fuel consumption and lower CO2 emissions, as well as a significant improvement in noise compared to previous generation engines. Since its entry into service in 2016, the LEAP engine has enabled our customers to save more than 20 million tons of CO2 compared to previous generation engines.
