Abstract :
Aircfrat use nose wheel steering system when landing, take off and
landing. In the research discuses the problem of nose wheel steering system B737
? 800 to minimize problems ini nose wheel steering system. The stage of this
research are to study the work system of nose wheel steering. Then look for the
cause of the problem using the FMEA analysis method. This research is based on
data from AFML (aircraft Flight and Manual Log) of the B737 ? 800 Aircraft
from January 2020 to Junu 2021 at Lion Airline. The results showed that the
problem of nose wheel steering system in the failure mode analysis process using
FMEA method data in the highest RPN ( Risk priority Number) value is 175 with
the case steering collar dan torQ link need lubrication and case Tire pressure that
caused by the lack of lubrication on the component and different pressure in tire.
Then it is necessary to do inspection before flight.
