Abstract

The Grob G120TP-A aircraft is a single-engine turbo propeller trainer aircraft. The engine type is Roll Royce 250-B17F. The oil system on this engine functions to supply oil as needed, which is measured by pressure, temperature, and oil flow rate. to carry out a dry-sump lubrication system, where the oil tank is located on the airframe which is placed on the engine mounting. The Grob G120TP- A aircraft has a special inverted flight oil system which is designed so that the lubrication of the aircraft continues to work normally when the aircraft is in the inverted position. In the period from 2016 to 2020, 88 failures were found in the oil system. In this study, direct observation and fault tree analysis were used to determine the cause of the failure of the Over Temperature Oil System on the Grob G 120 Tp-A aircraft. This method is used to identify the risks that play a role in the occurrence of failure. The results of the analysis using the fault tree analysis method with the top event over temperature oil system obtained 5 intermediate events and 12 basic events, and the component that most often results in over temperature oil system is the oil filter.
