SECTION 3
CESSNA
MODEL R172K
EMERGENCY PROCEDURES
NOTE
If sufficient ground personnel are available (and fire is
on groun~ and not too dangerous) move airplane away
t
fhromh th.e fire by pushing rearward on the leading edge of
e onzontal stabilizer.
(7) Fire D amage -- INSPECT, repair damage or replace damaged
components or wiring before conducting another flight.
ENGINE FIRE IN FLIGHT
(1) Throttle -- CLOSE.
(2) Mixture -- IDLE CUT-OFF.
(3) Fuel Shu toff Valve -- OFF.
(4) Master Switch -- OFF.
(5) C~bin Heat and Air -- OFF (except overhead vents).
(6) Airsp~ed -- 10? KIAS (If fire is not extinguished , increase glide
sp.eed to fmd an airspeed which will provide an incombustible
mixture).
(7) Fo.rced Land~ng -- EXECUTE (as described in Emergency Land-
mg Without Engme Power). Do not attempt to restart engine.
ELECTRICAL FIRE IN FLIGHT
(1) Master Switch -- OFF.
(2) All Other Switches (except ignition switch) -- OFF .
(3)
Vents/Cabin Air/Heat -- CLOSED .
(4)
Fire Extinguisher -- ACTIVATE (if available).
!WARNING'
After discharging an extinguisher within a closed cabin
ventilate the cabin. '
If fire appears out and electrical power is necessary for continu-
ance of flight:
(5) Master Switch -- ON.
(6)
Circuit Breakers -- CHECK for faulty circuit, do not reset.
(7) Radi?/Electri~al ~witches -.- ON one at a time, with delay after
each until short circuit is localized.
(8) Vents/Cabin Air/Heat -- OPEN when it is ascertained that f.
. 1 t 1 . .
ire
is comp e e y extmgmshed.
CABIN FIRE
(1) Master Switch -- OFF.

SECTION 3
EMERGENCY PROCEDURES
(2) Vents/Cabin Air/Heat -- CLOSED (to avoid drafts).
(3) Fire Extinguisher -- ACTIVATE (if available).
!WARNING'
After discharging an extinguisher within a closed cabin,
ventilate the cabin.
( 4) Land the airplane as soon as possible to inspect for damage.
WING FIRE
(1) Navigation Light Switch -- OFF.
(2) Strobe Light Switch (if installed) -- OFF.
(3) Pitot Heat Switch (if installed) -- OFF.
NOTE
Perform a sideslip to keep the flames away from the fuel
tank and cabin, and 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 tempera-
ture that is less conducive to icing.
(3) Pull cabin heat control full out to obtain maximum windshield
defroster airflow.
(4) Increase engine speed to minimize ice build-up on propeller
blades.
(5) Watch for signs of induction air filter ice and regain manifold
pressure by increasing the throttle setting.
(6) Plan a landing at the nearest airport. With an extremely rapid
ice build-up, select a suitable "off airport " landing site.
(7) With an ice accumulation of 1/ 4 inch or more on the wing lead-
ing edges, be prepared for significantly higher stall speed.
(8) Leave wing flaps retracted. With a severe ice build-up on the
horizontal tail , the change in wing wake airflow direction caused
by wing flap extension could result in a loss of elevator effective-
ness.
(9) Open left window and, if practical , scrape ice from a portion of
the windshield for visibility in the landing approach .
