SECTION 3
EMERGENCY
PROCEDURES
LANDING WITHOUT ELEVATOR CONTROL
Trim for horizontal flight with
an
airspeed of approximately 65 KIAS
and flaps set to 20° by using throttle and elevator trim controls.
Then
do
not
change the elevator
trim
control
setting; control
the.
glide angle
by
adjusting power.
During the
landing flare (round-out), the nose will come down when
power is reduced and the
airplane may touch down
on
the
nosewheel before the main wheels. When
in
the flare, the elevator
trim control should
be
adjusted toward the full nose
up
position
and
the power adjusted
at
the same time so that the airplane will rotate
to a
horizontal attitude for touchdown. Close the throttle
at
touchdown.
FIRES
Improper starting procedures involving the excessive use of
auxiliary fuel pump operation can cause engine flooding
and
subsequent collection of fuel
on
the parking ramp as the excess fuel
drains overboard from the intake manifolds. This
is
sometimes
experienced
in
difficult starts
in
cold weather where engine preheat
service
is
not available. If this occurs, the airplane should be
pushed away from the
fuel puddle before another engine start is
attempted. Otherwise, there is a possibility
of
raw
fuel
accumulations
in
the exhaust system igniting during
an
engine start,
causing a
long flame from the tailpipe,
and
possibly igniting the
collected fuel
on
the pavement.
If
a fire occurs, proceed according
to the
checklist.
Although
engine fires are extremely rare
in
flight,
if
a fire iSI
encountered, the steps of the appropriate checklist should be
followed. After completion of this procedure, execute a forced
landing.
Do
not attempt to restart the engine.
The first sign of
an
electrical fire
is
usually the smell
of
bUrningl
insulation. The
checklist procedure should result
in
the elimination
of the fire.
