Abstract :
Boeing 737-900 ER aircraft, first launched on July 18, 2005 The aircraft was
first used by Lion Air. cockpit of the Boeing 737-900 ER (Extended Range), has been
equipped with a Head Up Display (HUD). The landing gear of the Boeing 737-900
ER has a tricycle type configuration with air/oil shock struts. Landing gear consists
of two parts, namely Main gear and Nose gear. To keep the aircraft safe and
controllable, the landing gear must maintained be regularly
In this study using the method of observation and information from various
sources. This study also uses the Fault Tree Analysis (FTA) method to determine the
root cause of the failure of the Wheel steering system on the Boeing 737 - 900 ER
aircraft.
The results of the research on the Steering system Boeing 737 - 900 ER aircraft
is to analyze the causes of failure in the Fault Tree Analysis (FTA) heel the steering
system using.obtained 3 basic events consisting of vibration, lubrication, corrosion
that can trigger the top event.
