		abstract={The hydraulic system has an important role in the operation of the Boeing 737-900 
ER aircraft starting when on the ground until the aircraft has flown. The hydraulic 
system is used to operate several components namely aileron, tail plane, rudder, air 
brake, flap, landing gear, and wheel brake. Seeing the importance of the existence 
of the hydraulic system, a simple recalculation is carried out to see a simple 
description of the hydraulic system maintenance on the Boeing 737 - 900 ER 
airplane. The recorded components that experienced many failures in the hydraulic 
system were Engine Driven Pump (EDP) and Electric Motor Driven Pump (EMDP) 
as is known that these two components are the main components that have an 
important role in the work of the hydraulic system on an airplane. The method used 
was Failure Mode And Effect Analysis (FMEA) that is an analysis carried out to be 
able to find the effects or impacts is likely to make damage that causes hydraulic 
system failure. The results of analysis using FMEA found 6 problems including EDP 
systems A and B including leak, bad condition, line fitting leakage, low pressure, 
press can't operate, and broken. The results of the analysis with the FMEA method 
obtained the results in the form of the highest Risk Priority Number (RPN) value of 
the EDP is the finding of a leak in the EDP component. The potential cause 
(dominant cause) of this failure case was a leak in the EDP component with an RPN 
value of 280.}
