Abstract :
Engine start system is one of the systems that exist in the engine, functioning as a start engine. When the engine operation, this system is very necessary reliability, if the system does not work, then the engine cannot be operated. In addition, the engine is part of the aircraft used for its movement. To improve its reliability, periodic monitoring, effective maintenance by means of program reliability planning must be performed. Reliability programs are used to control the reliability of an engine, system or component. In analyzing the program reliability of engine starting system, there are several research methods undertaken, namely FMEA method and weibull distribution method. The FMEA method is used because the reliability program analysis is performed based on failure, and to determine the failure mode that occurs. The weibull distribution method is used to measure the reliability of the components, determine the effectiveness of the treatment and can predict the age of the compound. In this study, weibull distribution calculation using MINITAB software. By analyzing the program reliability of engine starting system, it can be determined the value of ? (shape parameter) and RPN value. It can also determine that the starter generator is the dominant problem part of the engine starting system. From the calculation results obtained ? > 1 is ? = 3.88889, failure mode that has the highest RPN value is the starter motor not working caused by component damage (wear out) with the value of RPN 200. Based on the calculation results, the starter generator component failure worn, preventive maintenance is more effective to do with this failure. Spare parts should always be available to support maintenance and to achieve optimal operation.
