continued
operation
on "BOTH"
magnetos
is practicable.
If not,
switch
to the
good magneto
and proceed
to the
nearest
airport
for
repairs.
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 cause
for immediate
concern
because
an
orifice
in
this
line
will
prevent
a sudden loss of
oil from
the
engine
sump.
However,
a landing at
the
nearest
airport
is
advisable.
If a
total
loss of
oil pressure
is
accompanied
by a
sudden
rise
in
oil
temperature,
there
is reason
to
suspect
an engine failure
is imminent.
Reduce
engine
power
immediately
and select a suitable
for
ced 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)
Drag
over
selected
field
with
flaps 20° and 70 MPH airspeed,
noting
the
preferred
area for
touchdown
for
the
next
landing approach.
Then retract
flaps after
well
clear of all
obstacles.
(2)
On downwind leg,
turn
off all switches
except
the
ignition
and
master
switches.
(3) Approach
with
flaps
40° at
70 MPH.
(4)
Unlatch
cabin
doors
prior
to
final
approach.
(5)
Before
touchdown, turn
ignition
and
master
switches
"OFF."
(6)
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.
