LOSS
OF
OIL
PRESSURE
Loss of oil
pressure
may be
either
partial
or complete.
A
partial
loss of oil
pressure
usually
indicates
a
malfunction
in
the
oil
pressure
regulating system,
and
a
landing should
be
made as
soon
as
possible
to investigate
the cause
and
prevent
engine damage.
A
complete
loss of
oil
pressure
indication
may
signify
oil exhaustion
or
may
be the
result
of a faulty
gauge.
In either case,
proceed
toward
the
nearest
airport,
and
be
prepared
for a
forced landing.
If the
problem
is not
a
pressure gauge
malfunction, the
engine may stop
zuddenly.
Maintain
altitude
until zuch
time as a
dead stick
landing
can
be accomplished. Don't
change
power
settings
unnecessarily,
as
this
may hasten
complete
power
loss.
Depending on the circumstances,
it
may be advisable to
make an
off
airport
landing
while
power
is
still available,
particularly
if
other indications
of actual oil
pressure
loss, such as sudden
increases
in
temperatures,
or oil smoke,
are apparent,
and
an
airport
is
not close.
If
engine
stoppage
occurs,
proceed
to POWER OFF
LANDING.

If
problem
is not
an
empty
fuel
tank,
land as
soon as
practical
and
have engine-driven

pump
checked.
HIGH
OIL
TEMPERATURE
An
abnormaly
high oil temperature
indication may be caused
by
a low
oil
level, an
obstruction
in the
oil
cooler,
damaged
or improper
baffle
seals, a defective
gauge,
or other
causes.
Land
as
soon as
practical
at an appropriate
airport
and
have
the cause investigated
A
steady,
rapid rise
in
oil temperature
is a
sign of trouble. Land
at
the nearest airport
and
let a mechanic
investigate the
problem.
Watch the
oil
pressure gauge
for
an accompanying loss
of
preszure.
