Gas turbine maintenance – aero engines

In this paper, we discuss the history, background, and evolution of gas turbine maintenance of aero engines.The types and levels of maintenance have been discussed to develop an understanding of the reader on Aero Engine Aviation Maintenance.The layout, facilities, and the typical composition of a Gas Turbine Maintenance Establishment (GTME) of Aero Engines has been emphasized to provide an insight into the workflow in a typical GTME of Aero Engines.The role of effective logistics and supply chain management and its impact on the serviceability of the engines in a typical GTME of Aero Engines has also been covered in this paper.The challenges and the problems of the technicians, maintenance engineers, and maintenance set up and how they affect the high serviceability levels of Aero Engines have been highlighted.The current and future state of GTME have also been included in this paper.The scope for introduction and development of lean maintenance in GTME of Aero Engines to achieve high serviceability levels has also been looked into considering the increase in demand for civil aircraft for passenger and cargo service and for military aircraft for security in the next decade.
