MULYA SEJAHTERA TECHNOLOGY}, year={2022}, url={http://eprints.stta.ac.id/1247/}, abstract={Airconditioning system is a system that functions to support the comfort and safety of passengers on the plane. Some of the possible damage that occurs to the air conditioning system of aircraft is caused by age and poor maintenance factors. The problem that occurs on the Boeing 737-300 TRI-MG aircraft at Hangar hall e PT Mulya Sejahtera Technology Bandung is a problem with the recirculasion fan. In this study, the direct observation method was used to observe and analyze the handling of the Boeing 737-300 TRI-MG aircraft at Hangar hall e PT Mulya Sejahtera Technology Bandung. In addition, this study also uses the fault tree analysis method to obtain the root cause of the failure of the Boeing 737-300 TRI-MG aircondtioning system .The results of the research on the problems of the Boeing 737-300 TRI-MG Fuel system are problems with the recirculaion fan. These problems were solved by performing troubleshooting referring to AMM Boeing 737-300 task 21-21-22 for trouble shooting, AMM Boeing 737-300 task 21-21-22 for removal and installation of recirculasion fan and AMM Boeing. 737-300 task 21-21-22 for removal and installation of recirculasion fan. By using the fault tree analysis method.} }
