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 end anger 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. The results of the analysis of high level Inter Turbine Temperature trouble findings on the Bell 412 helicopter using the Fault Tree Analysis method, which found 10 basic events that could trigger the top event to occur. The cause that can result in a high level Inter Turbine Temperature is the compressor bleed valve component experiencing stuck open/close caused by damage to the component. Another cause is the occurrence of problems in the hot section caused by ignition faults, fuel injection faults, low compression, in the combustion chamber. And problems with the inter turbine temperature indicator caused by no electrical supply and thermocouple sensor fault.
