Abstract :
Booster pump is one component of an aircraft fuel system. Booster pumps are
often called auxiliary fuel pumps. The main function of the booster pump is to
supply fuel at the start of the engine, to move fuel from the auxiliary tank to the
main tank, croosfeeding or move fuel to maintain the balance of the aircraft, as a
backup system or help pressure fuel if there is a malfunction of the Engine Driven
pump (EDP).
Booster pump was found to be malfunctioning, which was found to be an
indication of low pressure from the booster pump. This is known from the cookpit
found the jet pump is on when the engine starts. This is an indication of the low
pressure of the booster pump. After checking, it is found that the cause is the
clogging of impurities in the booster pump. And rips on the booster pump filter.
To overcome this, replacement and renewal of filter types and repair using a
cleaning method using an ultrasonic cleaner are carried out. Aim so that the
clogging dirt can be released with frequency vibrations. Then it is assisted with
nitrogen pressure so that the dirt can be blown out but it also aims to minimize
damage during the repair process.
After the cleaning process is then carried out pressure testing to determine
the performance condition of the booster pump whether it can work normally or
has exceeded the limit of limitation. After repairing, testing and making sure the
booster pump can work normally, it can be stated that the booster pump is
serviceable.
