Abstract :
The fuel system is an important system on aircraft that is used to flow fuel from
the tank to the engine. Failure of the fuel system can cause the plane to crash, so it is
possible for the plane to have an accident and cause casualties. This study discusses the
reliability of the fuel system on the Boeing 737-500 aircraft which includes the failure
process of the Boost pump in the fuel system.
In this study, direct observation method was used to observe and analyze the
handling of Boeing 737-500 aircraft maintenance at PT. Merpati Maintenance Facility.
The subject of this research is the Boeing 737-500 fuel system. In addition, in this study
the fault tree analysis method was used to find possible causes that would exist in the
Boeing 737-500 fuel system problem. The troubleshooting and remove/install process
refers to ATA 28, AMM (PAGEBLOCK 28-22-41/417), (PAGEBLOCK 28-22-
41/423).
Functional tests were carried out to determine the condition of the braking
system has been successfully repaired using the fault tree analysis method related to
aircraft fuel system problems, the basic events obtained were FTA analysis obtained
basic events, namely broken cables, broken conectors, leaks, clogged corrosion,
damaged impellers, leaks in seals, corrosion, stuck open.
