EMERGENCY PROCEDURES
CESSNA
MODEL 172N
FORCED
LANDINGS
If all attempts
to restart
the engine
fail
and a
forced landing is
imminent,
select a suitable
field
and
prepare
for the landing
as
dis-
cussed
in
the
checklist
for
engine-off emergency
landings.
Before
attempting an
"off
airport" landing with
engine
power
avail-
able,
one
should drag
the
landing area at
a safe
but low altitude to
inspect
the
terrain for obstructions
and
surface
conditions,
proceeding
as
discussed
under the
Precautionary
Landing With Engine Power
checklist.
Prepare
for ditching
by securing
or
jettisoning
heavy
objects
locat-
ed
in
the baggage area
and collect
folded coats for
protection
of occu-
pants'
face
at
touchdown.
Transmit Mayday
message
on
121.5 MHz
giving
location
and
intentions.
Avoid a
landing
flare
because of
diffi-
culty
in
judging
height
over
a
water
surface.
LANDING
WITHOUT
ELEVATOR,
CONTR,OL
Trim
for horizontal
flight(with
an airspeed
of approximately
60
KIAS
and
flaps
set to
20")
by
using throttle and
elevator
trim control.
Then do
not
change
the elevatoi
trim
control
settingl
control
the
glide
angle
by
-
adjusting
power
exclusively.
At
flareout,
the
nose-down
moment resulting
from
power
reduction
is
an adverse factor
and
the
airplane
may hit
on
the nose
wheel.
Consequently,
at
flareout,
the elevator
trim control should
be adjusted toward the full
nose-up position
and
the
power
adjusted so
that
the
airplane
will
rotate
to
the horizontal
attitude
for
touchdown.
Close
the
throttle
at
touchdown.
FIRES
Although
engine fires
are
extremely
rare in
flight, the steps of
the
appropriate
checklist
should
be followed
if one
is encountered.
After
completion
of
this
procedure,
execute a
forced
landing.
Do not
attempt
to
restart
the engine.
The
initial indication
of
an
electrical
fire is
usually the odor
of
burn-
ing
insulation.
The
checklist
for this
problem
should
result
in
elimination
of the fire,
