Abstract
Data obtained by the engineering unit of PT. GMF Aeroasia shows that most of the delayed Citilink Indonesia Airbus A320 aircraft that occurred during 2015-2020 were caused due to a failure of an aircraft component, especially in the Engine Fuel and Control component. The Fuel and Control Engine System is a very crucial system and can cause an aircraft to be declared AOG (Aircraft On Ground) in the event of a failure on its components, it is necessary to evaluate the reliability value of each component. The components that were evaluated were Fuel pump, IDG oil cooler, Hydromechanical Unit (HMU), fuel flow transmitter, and EEC (Electronic Engine Control). The component that often fails is the fuel pump which is mostly caused by fuel leakage and low pressure. Fuel flow transmitter is a component that has a high reliability value with a reliability value of 70% when the component operates for 9000 hours. The types of maintenance that can be done are the discard task, restoration task and on-condition task for the fuel pump. IDG oil cooler is a discard task and combination task. HMU (Hydro-mechanical Unit), namely by using the discard task and on-condition task. Fuel flow transmitter by issuing on-condition task scheduling. The EEC (Electronic Engine Control) component of the type of maintenance performed is on-condition task. Keywords: Maintenance, Engine Fuel And Control, Reliability Data yang diperoleh oleh unit engineering PT. GMF Aeroasia menunjukkan bahwa sebagian besar delayed pesawat Citilink Indonesia Airbus A320 yang terjadi sepanjang tahun 2015-2020 disebabkan karena adanya kegagalan suatu fungsi dari komponen pesawat, terutama pada komponen Engine Fuel And Control. Sistem Engine Fuel And Control merupakan sistem yang sangat krusial dan bisa menyebabkan suatu pesawat dinyatakan AOG (Aircraft On Ground) bila terjadi kegagalan pada komponennya, maka perlu dilakukan evaluasi terhadap nilai keandalan (reliability) dari masing-masing komponen tersebut. Komponen yang dilakukan evaluasi yaitu Fuel pump, IDG oil cooler, Hydro-mechanical Unit (HMU), fuel flow transmitter, dan EEC (Electronic Engine Control). Komponen yang sering mengalami kegagalan yaitu fuel pump yang kebanyakan disebabkan oleh fuel leakage dan low pressure. Fuel flow transmitter merupakan komponen yang memiliki nilai keandalan yang cukup tinggi dengan nilai keandalan 70% ketika komponen beroperasi selama 9000 jam. Jenis perawatan yang dapat dilakukan yaitu discard task, restoration task dan on-condition task untuk fuel pump. IDG oil cooler yaitu discard task dan combination task. HMU (Hydro-mechanical Unit) yaitu dengan menggunakan discard task dan on-condition task. Fuel flow transmitter dengan mengeluarkan penjadwalan on-condition task. Komponen EEC (Electronic Engine Control) jenis perawatan yang dilakukan yaitu oncondition task. Kata Kunci : Maintenance, Engine Fuel And Control, Reliability
