ENGINE POWER LOSS IN-FLIGHT
Complete engine
power loss
is
usually caused
by
fuel flow
interruption,
and
power
will
be
restored
shortly
after
fuel flow
is
restored.
If
power
loss occurs
at
low
altitude,
the
first step is
to
prepare for
an
emergency
landing.
(See POWER OFF
LANDING.) Maintain
an airspeed of
at
least
80 MPH IAS,
and
if altitude
permits,
proceed as follows:
1. Fuel
Selector
-
switch
to
another tank
containing
fuel.
2. Electric Fuel Pump
-
On
3. Mixture
-
Rich
4.
Carburetor Heat
-
On
5.
Engine Gauges
-
check
for
an
indication of
the cause
of Power
Loss.
6. Primer
-
Check Locked
7.
If
no
fuel pressure is
indicated,
check tank selector
position
to
be
sure
it
is
on a tank containing
fuel.
When Power

Restored:
8.
Carburetor

1. Ignition Switch
-
"L" then
"R"
then
back
to
"BOTH".
2. Throttle
arrd
Mixture
-
Different
settings.
(This
may
restore
power if problem is
too
rich
or too
lean
a
mixture,
or
partial fuel
system
restriction).
3. Try
another
fuel
tank
-
(Water in
the
fuel
could
take
some
time
to
be
used up, and
allowing the engine to windmill
may restore
power.
If
power
loss
is due
to
water,
fuel
pressure
indications
will
be
normal).
