Products
CRMA provides its customers with repair and overhaul services for a comprehensive range of products. As an AIR FRANCE INDUSTRIES repair “Center of Excellence”, CRMA is continually upgrading its capabilities and technology to meet market requirements. With the support of its Engineering Department, CRMA is continuously developing new repair solutions for its customers.
This is notably the case for the GP7200 Very Big engine (VBE), which has now joined the list of engines handled by CRMA, alongside the CF6, CFM56 and GE90. Selected by Engine Alliance (EA) as the “Primary Source” for combustion chambers, TCFs (Turbine Center Frame), and GP7200 harnesses, CRMA is currently the sole service provider worldwide for this type of repairs.
This has strengthened CRMA’s position on the Engine MRO segment and more especially on that of VBEs. As it constantly seeks to reduce maintenance costs, CRMA is 100% committed to improving reparability rates for its customers.
CRMA also provides a broad range of repair and overhaul services for aircraft components and military modules.
