LOW
OIL
PRESSURE.
If low
oil
pressure is
accompanied
by
normal oil
temperature, there
is
a
possibility
the oil
pressure
gage or
relief
valve
is
malfunctioning.
A
leak in the line to the gage
is
not
necessarily
cause
for
an immediate
precautionary
landing because an
orifice
in
this line will
prevent
a
sudden
loss
of
oil from the engine sump. However,
a
landing at
the
nearest
air-
port
would
be
advisable
to
inspect
the source
of
trouble.
If
a
total loss
of
oil
pressure is
accompanied
by
a
rise
in
oil tempera-"
ture, there is reason
to
suspect
an engine
failure is
imminent.
Reduce
engine power immediately and
select
a
suitable
forced
landing field.
Leave the engine running
at
low
power during the approach, using only
the minimum power
required
to
reach
the
desired
touchdown spot.
FORCED LANDINGS.
PRECAUTIONARY
LANDING WITH
ENGINE
POWER.
Before attempting an "off
airport”
landing,
one
should drag the land-
ing
area
at
a
safe but low altitude
to
inspect
the
terrain
for obstructions
and
surface
conditions, proceeding
as
follows:
(1)
Perform
"before landing" check.
(2)
Drag over
selected field
with
flaps
20°
and
75
MPH
airspeed,
noting
the
preferred area for
touchdown
for
the next landing approach.
Then
retract
flaps
upon
reaching
a safe altitude and
airspeed.
(3)
On downwind
leg,
turn
off
all
switches except the ignition and
master switches.
(4)
Approach with
flaps
40°
at
75
MPH,
(5)
Unlatch cabin doors
prior
to
final approach.
(6)
Before touchdown,
turn
ignition and
master
switches
"OFF."
(7)
Land
in a slightly
tail-low attitude.
EMERGENCY
LANDING
WITHOUT ENGINE POWER.
If
an engine stoppage
occurs, establish
a
flaps-up
glide
at
80 MPH.
If
time
permits, attempt
to
restart
the engine
by
checking for fuel quan-
tity,
proper
fuel
selector
valve position, and mixture control setting.
Also check that engine
primer is full
in and locked and ignition switch
is
properly
positioned.
