On-site maintenance

At Safran Aircraft Engines, our mobile teams perform a wide range of high value-added maintenance operations on-wing, on-site at customers or in our workshops. We provide operators of CFM56, LEAP, SaM146 and GE90 engines with 24/7 technical assistance anywhere in the world. 

On-site and on-wing operations


Safran Aircraft Engines has dedicated teams ready to carry out on-site and on-wing operations. All work performed at operators serves the same objectives: meet quality requirements to guarantee flight safety, reduce maintenance costs and minimize engine downtime.

To request on-site maintenance, please contact our Customer Support Center, which is available 24/7. 



All around the world, the Safran Aircraft Engines Line & Site Operations teams provide 24/7 assistance and technical expertise for operations, specializing in on-site maintenance. They carry out high value-added work in line with customer requirements, on-wing, on-site at customers or in our workshops. The Line & Site Operations teams perform more than 400 on-site operations every year. 


Safran Aircraft Engines also offers a range of LRU (line replaceable unit) services, with various options covering equipment repair and availability requirements for the CFM56n LEAP, SaM146 and GE90, which can be disassembled on wing.

From a simple Time & Material option to our Repair Pool solution, the LRU service is an agile and effective response to customer requirements. Safran Aircraft Engines maintains an inventory of over 1,000 different LRU parts and assemblies at our dedicated logistics hub. We can also hold inventories of critical LRUs on customer premises. Our LRU service can deliver parts to customers anywhere in the world and work locally with them to address all AOG situations. 


Safran Aircraft Engines designs all the tools needed for line and shop maintenance of CFM56, Sam146 and GE90 engines. We sell and distribute these tools and also offer advice. The tools needed for LEAP engine maintenance are sold by three major CFM-licensed suppliers. Safran Aircraft Engines provides operators and MRO workshops with assistance, technical support and aftersales service (maintenance, repair and replacement solutions) for all the tools we sell.
