abstract={The Boeing 737-900ER aircraft is the newest variant of the Boeing 737
aircraft. During operation, various problems will certainly be found. One of the
problems that occurs is the failure of the APU Lubrication System. The right type
of maintenance is needed to minimize or prevent failure. These failures will be
analyzed using the Failure Mode and Effect Analysis method to determine the RPN
value in each failure mode in order to be able to recommend a suitable type of
treatment.
The method used is the Failure Mode and Effect Analysis (FMEA) and Risk
Priority Number (RPN) methods. The first step is to identify failures in each
component. each failure mode and failure effect that occurs in each component is
translated into the FMEA table. After that, an analysis of the Risk Priority Number
is carried out by looking at the severity, occurrence and detection levels of each
component.
The conclusion obtained is identification of failures that occur in the APU
lubrication system, namely there are 22 failures in the APU lubrication system, 11
cases of Oil clog failure, 7 cases of Oil leak failure, 4 cases of Oil Temperatue
failure. Failure cases that have a high critical failure modes are oil clog with an
RPN value of 288 and oil leak with an RPN value of 256, while moderate critical
failure modes is oil temperature with an RPN value of 168.}
