The method that GMF used currently not able to determine cost and workscope on aircraft engine maintaince in future treatments. In order to make engine maintenance cost <br /> <br /> <br /> savings, required a maintenance optimization methods discussed thoroughly from the first shop visit until engine scrap. That can be optimized if there is the actual data the current engine maintenance cost. <br /> <br /> <br /> In this research, the development of methods that can determine the scope of work that needs to be done when maintenance the engine for optimizing maintenance cost per <br /> <br /> <br /> engine flight cycle. Determinant variables in order to optimize the maintenance cost is remaining age of Life Limit Parts (LLP) to be replaced and the Exhaust Gas Temperature (EGT) margin. The method is tested with past data and then implemented to obtain the remaining age of LLP which should be replaced in order to produce the most optimum engine maintenance cost. <br /> <br /> <br /> Tests proved that the new method is valid. For engines with a thrust rating of 20,000 lbs and 22,000 lbs remaining age of Life Limit Parts (LLP) to be replaced in order to produce the most optimum engine maintenance cost are the LLP with the remaining age under the 5,000 FC, for the machine with a thrust rating of 23,500 lbs is the LLP with the remaining age under the 1,250 FC. This implementation also shows that the machine with a thrust rating of 23,500 lbs is not recommended for use in Indonesia.
