14.3 FUEL TANKS
14.3.1 DESCRIPTION
Where wing tanks are fitted, the composite tanks are located in the left & right hand wings. A header
tank is also fitted
– either under the passenger’s seat, under the baggage shelf or behind the rear
sound curtain. Wing tanks are an integral part of the wing structure whereas header tanks are non-
structural and may be removed if required.
A sump drain plug is provided for each tank.
14.3.2 FUEL TANK REMOVAL
As the wing fuel tanks are part of the wing integrity, these fuel tanks cannot be removed.
The header tanks may be removed if necessary to check outlet strainers etc.
-
Drain fuel from wing tanks.
-
Remove the drain plug and drain the fuel from the header tank.
-
Remove the cover from the header tank enclosure. For kit-built models where the tank is under
the passenger’s seat this may require cutting a hole into the seat pan.
-
Remove tank restraints.
-
Loosen hose clamps, remove hoses & remove tank.
-
Installation is the reverse of removal.
Main fuel tanks installed in the cabin can be removed:
-
Drain the tank.
-
Loosen the tank restraining straps
-
Loosen and remove the filler hose between the tank and the fuel filler on the outer skin of the
fuselage.
-
Disconnect the earth wire between the tank and the fuel filler earth point.
-
Lean the tank to one side to allow access to disconnect the fuel line.
-
In some cases it may be necessary to disconnect the aileron cables to allow room for the tank to
pass.
-
Remove the tank from the aircraft.
14.3.3 FUEL TANK INSPECTION
Leaks can normally be found by visual inspection: AVGAS in particular will leave dye stains where
leaks have occurred. If leaks are found contact Jabiru Aircraft for a repair procedure.
Visually inspect the tank and fittings for corrosion, damage and contamination.
14.3.4 FUEL TANK INSTALLATION
For installation, reverse removal procedure given above.
