Abstract :
The nose wheel steering is a component of the nose landing gear that serves
to cafable the pilot direct the aircraft when it is taxied on the ground as disered.
The pilot will have difficulty in directing the nose wheel of the aircraft if there is
damage to the nose wheel steering. This happens because the aircraft operates
frequently, thereby reducing the performance of these components. To keep the
aircraft safe and airworthy, regular maintenance must be carried out. In carrying
out maintenance on the Fokker F27-500F aircraft, an indication of damage to the
nose landing gear was found, namely the nose wheel steering system. Therefore,
troubleshooting was carried out to solve the problem.
Solving problems in this study using observation methods, data collection
and fault tree analysis methods used to analyze the causes of damage to the nose
wheel steering. This research also refers to AMM Section 32-50-00 when doing
troubleshooting work to avoid technical errors. The troubleshooting process is
carried out by checking the nose wheel steering, namely the pneumatic line, control
valve, and centralizer unit.
Troubleshooting in this study uses observation methods, data collection
methods and fault tree analysis methods used to analyze the causes of damage to
the nose wheel steering. This research also refers to AMM Section 32-50-00 when
doing troubleshooting work to avoid technical errors. The troubleshooting process
is carried out by checking the nose wheel steering, namely the pneumatic line,
control valve, and centralizer unit. The results of this troubleshooting were then
analyzed using the fault tree analysis method and it was found that the damage
occurred to the tubing control valve which had a leak caused by aircraft vibrations,
damage to the screaper seal and clutch piston that was worn out. Then analyzed by
fault tree analysis method which obtained 6 basic events, namely seal crack,
fatigue, tubing leakage, connector lead loose, clutch piston worn out, piston
damage (FOD). So that a replacement was carried out according to the AMM
Fokker F27-500F, after the replacement was carried out then an operational test
was carried out and the results were that the nose wheel steering returned to
normal.
