Abstract :
Anti-icing is a system in aircraft to prevent the formation of ice on critical
aircraft structures or parts that can interfere with aircraft mobility. The anti-icing
system is powered by 2 main sources, namely hot air drawn from the high
pressure compressor and electric heat. The icing that occurs on the aircraft
results in increased drag, reduced lift, increased weight on the aircraft, and
reduced thrust. In addition, the ice formed can also cause damage to important
components on the plane.
In this study, the method used is direct observation to observe and analyze
the troubleshooting process on the anti-icing engine. In addition, this study also
uses the fault tree analysis method to determine the root cause of the damage to
the Boeing 737-800 NG anti-icing engine.
The result of the research on the anti-icing engine damage is that the
thermal anti-ice component is stuck. So it is necessary to replace these
components according to the procedures for AMM Boeing 737-800 NG task 30-
21-11-000-801. The results of the analysis using the fault tree analysis method
obtained 15 basic events, namely Control Solenoid Fault, Valve Corrosion, Disk
Bending, Oxidation, Corrosion, Cable Broken, Lamp Weak, Connector Loose,
Pipe Leaking, Short Circuit
