AND
SYSTEMS DESCRIPTION
ENTRANCE DOORS AND CABIN WINDOWS
(Continued)
Exit from the
airplane is accomplished by rotating the door handle
from the LOCK position, past the CLOSE position, aft to the OPEN
position and pushing the door open. To
lock the airplane, lock the
right cabin door with the inside
handle, close the left cabin door,
and using the ignition key,
lock the door.
The
left
and
right cabin doors are equipped with openable windows
which are
held
in
the closed position by a detent equipped latch
on
the lower edge
of
the window frame. To open the windows, rotate
the
latch upward. Each window is equipped with a spring- loaded
retaining arm which will help rotate the window outward, and hold it
there.
If
required, either window may be opened at any speed
up
to
163
KIAS. The rear side windows and rear windows are of the fixed
type and cannot
be
opened.
CONTROL
LOCKS
A control lock is provided to lock the aileron and elevator control
surfaces to prevent damage to these systems
by
wind buffeting
while the airplane is parked. The lock consists of a shaped steel
rod
and flag. The flag identifies the control lock
and
cautions about its
removal before starting the engine. To install the control lock, align
the hole
in
the top of the pilot's control wheel shaft with the hole
in
the top of the shaft collar
on
the instrument panel and insert the rod
into the
aligned holes. Installation of the lock will secure the ailerons
in
a neutral position and the elevators
in
a slightly trailing edge
down position. Proper installation
of
the lock will place the flag over
the ignition switch.
In
areas where high or gusty winds occur, a
control surface lock should
be
installed over the vertical stabilizer
and
rudder. The control lock
and
any other type of locking device
should be removed prior to starting the engine.
