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 a low altitude,
the
first step is
to
prepare
for
an
emergency landing
(refer
to
Paragraph 3.13). An airspeed of at least
97 KIAS should be maintained.
If altitude permits, switch
the
fuel selector
to
another tank containing fuel
and
turn the
auxiliary fuel
pump
to*"HI." Move
the
mixture control
to
"RICH"
and
the
alternate air
to
"OPEN." Check
the
engine
gauges
for
an indication
of
the
cause of
the
power
loss. If no fuel
pressure
is indicated,
check
the tank
selector position
to
be sure it is
on a
tank
containing fuel.
When
power
is restored
move
the alternate air
to the
"CLOSED" position and
turn
"OFF"
the
auxiliary fuel
pump.
If
the
preceding steps
do not restore power, prepare for an emergency landing.
If
time permits, turn the
ignition switch
to
"L"
then to "R" then back
to
"BOTH."
Move
the throttle
and mixture control levers
to
different settings. This
may
restore power if
the
problem is
too
rich or
too
lean a mixture or
if
there
is a partial fuel
system restriction.
Try other fuel
tanks. Water in the fuel
could
take
some
time to be used up, and allowing
the
engine
to
windmill may restore power.
If power is due
to
water,
fuel
pressure
indications will be normal.
If engine failure was caused by fuel exhaustion
power will not be restored after switching fuel
tanks
until the empty
fuel lines are filled. This may require up
to ten
seconds.
If power is not regained, proceed with
the
Power
Off Landing
procedure
(refer
to the
emergency
check list and Ihragraph
3.13).
*The "HI" position on
the
auxiliary fuel pump switch is guarded and must
be unlatched before it can be
activated.
