Abstract :
The brake system on the aircraft is one of the systems that is necessary for landing and requires high energy to brake. The aircraft uses three types of braking, wheel brakes, thrust reversers, and ground spoilers. Wheel brake works by stopping the wheel to reduce the speed of the aircraft. The friction between the wheel and the runway is what stops the movement. This research was conducted on a Boeing 737- 800 NG, when the aircraft touchdown, the aircraft lost the ability to do wheel braking so that the pilot used thrust reverse to stop the aircraft. In this thesis, using observation and information method fromvarious sources. Furthermore,it also uses Fault Tree Analysis (FTA) method to determine the root cause of the failure of the wheel brake system on the Boeing 737-800 NG aircraft. The result of research on wheel brake system problem Boeing 737-800 NG, there is a problem on the brake accumulator and alternate brake selector valve. From these problems, then do a problem-solving process that refers to AMM Boeing 737-800 task 32-41-51 for brake accumulator and AMM Boeing 737-800 task 32-41- 93 for alternate brake selector valve. By analyzing the causes of failure of the wheel brake using the FTA method, we get 5 basic events consisting of fitting leak, packing/seal broken, connector loose, electrical connector disconnect, connector corrosion which can trigger the top event.
