Abstract

One parameter that greatly affects engine performance is the inter Turbine Temperature (ITT), Inter Turbine Temperature is the engine's internal temperature between the compressor turbine and the power turbine. When the Inter Turbine Temperature indicator shows the temperature is outside the normal limit, then this is an indication of a problem with the engine, and has the potential to endanger flight safety. The failure analysis that appears on the increase in the Inter Turbine Temperature is based on observations and information obtained from the field instructor. In addition to using the observation method, this study also uses the fault tree analysis method to find the cause of the high level of inter turbine temperature problem. After knowing the problem, an inspection and troubleshooting process is carried out to resolve and overcome these problems. Perform inspection troubleshooting inspection Based on Ref. T.O. 1 T-KT1B-22 REV. A, page 5- 91.92) regarding the increase in the high level of Inter Tubine Temperature, and it was found that the problem causing the high level of Inter Turbine Temperature was the excessive amount of compressed air supply caused by the compressor bleed valve component which is in charge of regulating the air entering the compressor. stuck close / unable to open.
