cold weather operations can not be overstressed.
BATTERY. Battery should be maintained at full
charge during cold weather to prevent freezing. After
adding water in freezing temperature, charge battery
to mix water and electrolyte. A frozen battery may
explode when
subjected to a high charge rate. Cor-
rosive damage to the area adjacent to an exploded
battery will result if the electrolyte solution is not
removed.
Instructions for remOving spilled electrolyte
are provided in this section. The battery should be
removed and stored in a warm place, if the aircraft is
to remain idle for an extended period of time.
FUEL SYSTEM. Condensation is more likely to occur
in cold weather due to a more rapid and positive divi-
sion of
moisture content from other fuel properties.
If at all pOSSible, use fueling facilities that filter
moisture from the fuel. If fueling facilities with filters
are not available, filter fuel through a good grade
chamois. Fill tanks with correct grade (octane) fuel
as soon as possible after landing to reduce the possi-
bility of condensation and ice formation in the tank.
Fuel extracted from the fuel tank drains before engine
starting, deserves a more critical examination when
aircraft is being operated in cold weather.
POST FLIGHT MAINTENANCE. Cold weather opera-
tion demands procedures that are in addition to normal
post flight maintenance procedures. The engine should
be allowed to
run dry by clOSing the fuel selector valve.
Fill fuel tanks immediately after flight. If shelter is
not available, tie aircraft down, install wing and en-
gine compartment covers when snow is in the forecast,
and be sure all openings are closed or covered.

GROUND EMERGENCY PROCEDURES
Emergency procedures must be accomplished as
rapidly as possible should an emergency arise. It is
therefore suggested that steps pertaining to each
emergency be committed to memory in order to ac-
celerate the procedure and minimize any possible
damage. The best solution is to avoid emergenCies
by following the procedures contained throughout this
manual.
ENGINE FIRES
If a fire develops in the engine compartment during
engine starting, continue the engine start in an attempt
to blow the fire out. If the fire persists, proceed as
follows:
a. Cowl flaps - CLOSE.
b. Mixture control - IDLE CUTOFF.
c. Fuel selector valve - OFF.
d. Cabin ventilation control - CLOSED.
e. Ignition and master battery switch - OFF.
f. Abandon aircraft.
ELECTRICAL FIRES
Circuit breakers will automatically trip and stop the
current flow to a shorted circuit. However, as a
safety precaution in the event of an electrical fire,
turn master battery switch OFF. Use a fire extin-
guisher approved for electrical fires to extinguish flame.
