Abstract

The engine oil system of the GROB G 120 TP-A aircraft is a system for circulating oil from the oil tank to the moving components of the engine. The main components of the engine oil system consist of an oil tank, oil cooler, oil filter, oil sensor and oil pressure switch. This study aims to determine the availability and reliability of the oil system on the Grob G 120 TP-A aircraft using the Weibull distribution method. The data used to calculate reliability is damage data from the components being analyzed. From the calculation using this method, it can be seen that the availability of the engine oil system of the GROB G 120 TP-A aircraft decreases over time. The engine oil system of the GROB G 120 TP-A aircraft has the highest availability of 0.9968 or 99.68% if preventive repairs are carried out with a distance of 300 flight hours. The longer the interval of use of the engine oil system of the GROB G120-TPA aircraft, the higher the failure rate of the engine oil system of the GROB G120-TPA aircraft. The GROB G120-TPA aircraft engine oil system may be operated for a maximum of 4,040 flight hours, because if it is operated beyond that time, the level of damage is likely to be more than 10%.
