1. Perform engine shutdown.
2. FIRE PULL handle – Pull.
3. Land as soon as practicable.
d. Fuel Crossfeed. Fuel crossfeed is normally
used only during single-engine operation. The fuel
from the dead engine side may be used to supply the
live engine by routing the fuel through the crossfeed
system. During extended flights, this method of fuel
usage will provide a more balanced lateral load
condition in the aircraft. For fuel crossfeed, perform
the following procedure:
1. AUX TRANSFER switches – AUTO.
NOTE
With the FIRE PULL handle pulled, the fuel
in the auxiliary tank for that side will not be
available (usable) for crossfeed.
2. STANDBY PUMPS – OFF.
3. CROSSFEED switch – As required.
4. FUEL
CROSSFEED
annunciator
illuminated – Check.
NOTE
With the FIRE PULL handle pulled, the
FUEL PRESS light will remain illuminated
on the side supplying fuel.
5. FUEL PRESS light extinguished – Check.
6. Fuel quantity – Monitor.
e. NAC LOW Light Illuminated. Illumination of
the #1 and #2 NAC LOW caution light indicates that
the affected tank has 20 minutes C 30 minutes D T
of usable fuel remaining at sea level, at normal cruise
power consumption rate. Proceed as follows:
Failure of the fuel tank venting system will
prevent the fuel in the wing tanks from
gravity feeding into the nacelle tank. Fuel
vent system failure may be indicated by
illumination of the #1 or #2 NAC LOW
caution light with greater than 20 minutes
C 30 minutes D T of usable fuel indicated in
the main tank fuel system. The total usable
fuel remaining in the main fuel supply
system with the LOW FUEL caution light
illuminated may be as little as 114 pounds,
regardless of the total fuel quantity
indicated. Continued flight may result in
engine flameout due to fuel starvation.
1. Usable fuel remaining – Confirm.
2. Land as soon as possible.
9-28. ELECTRICAL SYSTEM EMERGENCIES.
a. DC GEN Light Illuminated. Illumination of a
#1 or #2 DC GEN caution light indicates failure of a
generator or one of its associated circuits, generator
control unit. If one generator system becomes
inoperative, all nonessential electrical equipment
should be used judiciously to avoid overloading the
remaining generator. The use of accessories that
create a very high drain should be avoided. If both
generators are shut off due to either generator system
failure or engine failure, all nonessential equipment
should be turned off to preserve battery power for
extending the landing gear and wing flaps. When a
DC GEN light illuminates, perform the following:
1. GEN switch – OFF, RESET, then ON.
IF THE GENERATOR DOES NOT RESET:
2. GEN switch (no reset) – OFF.
3. Operating loadmeter – 100% maximum.
b. Both DC GEN Lights Illuminated.
1. All nonessential equipment – Off.
2. Land as soon as practicable.
c. Excessive Loadmeter Indication (Over
100%). If either loadmeter indicates over 100%,
perform the following procedure.
1. Loadmeter – Monitor.
