LONDON – Singapore MRO giant ST Engineering has announced its expansion into maintenance and support for the LEAP-1B engine. Its new test cell support capability is expected to be ready by the end of 2023.

The firm’s expansion into LEAP-1B test cell capability follows the setting up of quick-turn services for the engine in February this year, and the receipt of approval from EASA, FAA and CAAC.

ST Engineering will work with testing and technology development solutions provider, Calspan Aero System Engineering (Calspan ASE), in setting up LEAP-1B test cell capability at its engine MRO facility in Singapore.

The proposed LEAP-1B test cell facility will become the first in the Asia-Pacific region to implement Calspan ASE’s latest technologies, found in their upgraded Data Acquisition Control System and proprietary software, ASE2000LX Version 8.

The new digital tools to be introduced by ST Engineering will thus enhance the efficiency and performance of aero-engine test cells through a system of automated engine monitoring, process repeatability and data analytics.

Management statements


Tay Eng Guan, Vice President and General Manager of Engine Services at ST Engineering said, “We are excited to increase our engine MRO offerings by developing a high-quality and environmentally-friendly test cell for the LEAP-1B engine.”

“This is another step for us in developing full MRO services for the engine, and we look forward to providing the service to our valued customers by end-2023.”

David Meier, President of Calspan ASE added, “Calspan ASE is very proud to continue our long relationship with ST Engineering by adding test-enabling hardware and updating control systems to allow efficient testing of the LEAP-1B engine in Singapore.”

“We look forward to bringing this important capability on-line to meet the growing capacity needs for LEAP MRO to the region.”

About ST Engineering


ST Engineering operates engine MRO facilities out of Singapore and Xiamen, China, and currently has test cell capabilities for the CFM56-5B and -7B engines at both facilities.

As part of its commitment to sustainability, ST Engineering will also work with Calspan ASE to incorporate energy and fuel-efficient technologies into its existing test cells.

The MRO already has engine maintenance capability, including on-wing maintenance capability. Between the two facilities, the firm has a total annual capacity for overhaul and maintenance of over 450 engines.

They have delivered more than 10,000 engines and overhauled more than 1,500 CFM56 engines since 1999.
