3. Fuel Shutoff Valve -- Pull Out (OFF).
4. Master Switch -- OFF.
5. Cabin Heat and Air -- OFF (except overhead vents).
6. Airspeed -- 105 KIAS (If fire is not extinguished, increase glide speed to
find an airspeed - within airspeed limitations - which will provide an
incombustible mixture).
7. Forced Landing -- EXECUTE (as described in Emergency Landing without
Engine Power).
ELECTRICAL FIRE IN FLIGHT
1. Master Switch -- OFF.
2. Avionics power Switch -- OFF.
3. All Other Switches (except ignition switch) -- OFF
4. Vents, Cabin Air, Heat -- CLOSED.
5. Fire Extinguisher -- ACTIVATE.
WARNING
AFTER DISCHARGING FIRE EXTINGUISHER AND ASCERTAINING THAT FIRE
HAS BEEN EXTINGUISHED, VENTILATE THE CABIN.
If fire has been extinguished and electrical power is necessary for continuance
of flight to nearest suitable airport or landing area:
6. Master Switch -- ON.
7. Circuit Breakers -- CHECK for faulty circuit, do not reset.
8. Radio Switches -- OFF.
9. Avionics Master Switch -- ON.
10. Radio/Electrical Switches -- ON one at a time, with delay after each until
short circuit is localized.

completely extinguished.
CABIN FIRE
1. Master Switch -- OFF.
2. Vents/Cabin Air/Heat -- CLOSED (to avoid drafts).
3. Fire Extinguisher -- ACTIVATE.
WARNING
AFTER DISCHARGING FIRE EXTINGUISHER AND ASCERTAINING THAT FIRE
HAS BEEN EXTINGUISHED, VENTILATE THE CABIN.
4. Land the airplane as soon as possible to inspect for damage.
WING FIRE
1. Landing Taxi Light Switches -- OFF.
2. Navigation Light Switch -- OFF.
3. Strobe Light Switch -- OFF.
4. Pitot Heat Switch -- OFF.
NOTE
Perform a sideslip to keep the flames away from the fuel tank and cabin. Land
as soon as possible using flaps only as required for final approach and
touchdown.
ICING
INADVERTENT ICING ENCOUNTER
1. Turn pitot heat switch ON. (if installed )
2. Turn back or change altitude to obtain an outside air temperature that is
less conducive to icing.
3. Pull cabin heat control full out and open defroster outlets to obtain
maximum windshield defroster airflow. Adjust cabin air control to get
maximum defroster heat and airflow.
4. Increase engine speed to minimize ice build-up on propeller blades.
5. Watch for signs of induction air filter ice regain manifold pressure by
increasing the throttle setting.
6. Plan a landing at the nearest airport. With an extremely rapid ice buildup,
select a suitable "off airport" landing site.
7. With an ice accumulation of 1/4 inch or more on the wing leading edges,
be prepared for significantly higher stall speed.
8. Leave wing flaps retracted. With a severe ice buildup on the horizontal tail,
the change in wing wake airflow direction caused by wing flap extension
could result in a loss of elevator effectiveness.
9. Open left window and, if practical, scrape ice from a portion of the
windshield for visibility in the landing approach.
10. Perform a landing approach using a forward slip, if necessary, for improved
visibility.
11. Approach at 65 to 75 KIAS depending upon the amount of the
accumulation.
12. Perform a landing in level attitude.

LANDING WITH A FLAT MAIN TIRE

2. Wing Flaps – full down•
3. Touchdown -- GOOD MAIN TIRE FIRST, hold airplane off flat tire as long
as possible with aileron control.

LOW VOLTAGE ANNUNCIATOR (VOLTS) ILLUMINATES DURING FLIGHT
(Ammeter Indicates Discharge)
NOTE
Illumination of "the low-voltage light may occur during low RPM conditions
with an electrical load on the system such as during a low RPM taxi. Under these
conditions, the light will go out at higher RPM. The master switch need not be
recycled since an overvoltage condition has not occurred to deactivate the
alternator system.

2. Alternator Circuit Breaker -- CHECK IN.
3. Master Switch -- OFF (both sides).
4. Master Switch -- ON.
5. Low Voltage light -- CHECK OFF.
