Fuel Drain
The Jet fuels can have unwanted water that it collects
during airplane operation. There are many ways contaminants can occur in your
fuel, however, the most common issues happen due to atmospheric absorption,
condensation, and leaking in the fuel tank. Water is arguably the most damaging
type of contamination as it can cause a series of chain reactions.
It is necessary to drain the fuel tanks sumps
regularly to remove this unwanted water. Water can promote corrosion in fuel system components. If enough water
is present, it can form ice crystals in low temperatures and clog fuel lines,
filters, or components. This could disturb or even stop the fuel supply to the
engine.
It's important to use the approved drain tool to
extract fuel from the sump drain valve. And ensure that there are no leaks
coming from the valve after the drain tool is removed. Always refer to the approved updated AMM as a guideline when carrying out a water drain on fuel tanks. Importance should be given to the fuel drain. It may look simple but it plays an important safety role.
