WARRIOR
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
suddenly.
Maintain altitude until such 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
increase
in
temperatures,
or oil smoke,
are apparent, and an airport
is
not
close.
lf
engine
stoppage occurs,
proceed
to
POWER
OFF LANDING.

Check
on full
tank
If
problem
is
not an empty
fuel
tank, land as soon
as
practical
and
have the
fuel system
checked.
HIGH
OIL
TEMPERATURE
An abnormally
high oil temperature
indication may
be caused
by a
low oil
level,
an
obstruction
in the oil cooler,
damaged or improper
baffle
seals,
a def'ective
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
pressure.
