Ethiopian MRO Services has announced that is has developed a shop overhaul capability for CFM56-3 and CFM56-7 engines. The new facility, approved by the Ethiopian Civil Aviation Authority (ECAA) and the US Federal Aviation Administration (FAA), cost the MRO an estimated $21m to develop. The project included: expanding the existing engine maintenance shop, attaining the required machineries, equipment and tools, training, and upgrading the existing test cell. Ethiopian MRO already had full maintenance capability for both the 737 classic and 737NG - powered by CFM engines. The addition of the CFM56-3 and CFM56-7 should provide customers with a “convenient one stop shopping” for 737 fleet maintenance requirements. The new capability development took almost three years to complete with the assistance of General Electric (GE) Aviation.
