Identifikasi Penyebab Kegagalan Pada Air Cycle Machine Di Pesawat Boeing 737-800 PK-LBS

Abstract

The Boeing 737-800 aircraft has an Air Cycle Machine system which functions as air expansion and compression, changing hot air into cold air. This component is very important because if this component is damaged it will disturb passenger comfort, because it can cause a reduction in speed and will affect the loss of efficiency. The temperature will increase and the air flow in the aircraft will decrease. The purpose of this research is to find out the causes of failure in the Air Cycle Machine and find solutions to solve the problem. The data source is taken based on the Fault Isolation Manual (FIM) reference. After the author found the problem from the Fault Isolation Manual (FIM), the author carried out a visual check refers to the Aircraft Maintenance Manual (AMM) and the problem with the air cycle machine where the blade on the air cycle machine is stuck and cannot twist because it touches the compressor casing and to find items and also the location of the damaged part, you can see the Illustrated Parts Catalog ( IPC), after getting the damaged part, the author replaced the damaged part by looking at the Aircraft Maintenance Manual (AMM) to see how to remove, repair and install and also tested after carrying out the replacement to ensure the problem had been successfully resolved.
