Aircrafts are one of the most important means of transportation today. For aircrafts to be able to serve safely, their maintenance must be done in a timely and complete manner. In addition to regular maintenance, it may appear suddenly; there is also irregular maintenance performed in cases such as lightning strikes, bird strikes, and hard landings. Engine failures and maintenance has great importance in aircraft maintenance. Using the data recorded during the flight by flight data recorder, the engine health condition is monitored and the necessary maintenance procedures are carried out. In this study, the exhaust gas temperature was estimated using various data mining algorithms. Because exhaust gas temperature is one of the important parameters used to monitor the aircraft engine health condition. The obtained mining results show the Random Forest Algorithm has best estimation performance. With mining of exhaust gas temperature value, faults can be detected before costly maintenance and accidents. So preventive maintenance methods will be applied, aircraft engines will remain healthy, a significant reduction in the maintenance cost of the operator will be achieved, as well as flight safety and environmental protection.
