The fuel system comprises five drain points:
- a drain on the filter bowl,
- two drain valves on each tank, located on wing lower surface:
. one at the wing root, and
.
one outboard of the landing gear well.
These drains allow a draining of water or sediments that are contained in the fuel.
Fuel tank drain valves are provided with a slot which enables them to be opened
with a screwdriver.
WARNING
Fuel system draining shall be performed prior to the first flight of the day
and after each tank refueling, using a sampler to draw fuel at the two
drain valves of each tank and at the filter vent valve.
Filter clogging is indicated by a red filter bypass flag on the fuel unit that is
externally visible when an
inspection door located on the left side under the front
baggage compartment is open. A pushbutton adjacent to the inspection door
controls the illumination of a light that provides improved visibility of the clogging
indicator. This indicator shall be visually checked during preflight inspection.
