HANDLING. SERVICE & MAINTENANCE
FUEL CONTAMINATION
Fuel
contamination
is
usually
the
result
of
foreign
material
present in
the fuel
system,
and
may
consist
of
water,
rust,
sand,
dirt,
microbes
or
bacterial growth.
ln
addition, additives
that are
not
compatible with fuel or fuel system components can cause the
fuel
to
become contaminated.
Before each flight and after each refueling, use
a
clear
sampler
-cup and
drain
at
least
a
cupful of fuel from each fuel tank
drain
Itoiation
and from the fuel stiainer quick drain valve
to
determine
if
lcontaminants
are
present, and
to
ensure
the
airplane has
been
fueled with
the
proper grade
of
fuel.
I
el
drain points
again,
I
then
gentlY rock
the
move any
additional
epeated samples
from
all fuel drain points until all
contamination
has been
removed.
lf,
after repeated sampling, evidence of contamination still exists,
the
airplane should not be flown. Tanks should be drained and
system
purged
by
qualified maintenance personnel.
All
evidence
of
contamination must be removed before further flight.
lf the
airplane
has been seruiced with the improper fuel grade, defuel
completely
and refuel with the
correct grade.
Do not
fly
the
airplane
with
contaminated
or
unapproved fuel.
ln
addition, Owners/Operators who
are not
acquainted
with
a
particular
fixed
base
operator should be
assured
that the fuel
supply
has been checked for contamination and is properly filtered
before
allowing the airplane
to be
serviced. Fuel tanks should be kept
full
between flights, provided weight and balance considerations
will
permit,
to
reduce
the
possibility
of water condensing on the walls
of
partially
f
illed
tanks.
To
further reduce
the
possibility
of
contaminated
fuel,
routine
maintenance of the fuel system should be performed in
accordance
with
the
airplane Maintenance Manual. Only
the
proper
fuel,
as
recommended in this handbook, should be used, and fuel
additives
should not
be
used unless approved by Cessna and
the
Federal
Aviation Administration.
