CARGO DOOR
An optional cargo door, located adjacent to the cabin door. is a one-
piece, outward opening, side-hinged door. The cargo door provides a larger
opening when loading large, bul ky items. The door warning light on the an-
nunciator panel will illuminate if the cargo door is not securely latched.

WINDOWS
Six windows are provided on each side of the airplane. All windows are
unopenable. except the emergency exit window. A foul weather window is
incorporated into both the pilot's and copilot1s side window. The foul
weather windows may be opened during all ground operations and inflight.
Airspeed is not restricted with the foul weather
windo~s
open.
EMERGENCY EXIT WINDOW
The forward cabin window on the right side of the passenger compartment
can be opened for emergency exit or during ground operations. To open the
emergency exit window, remove the plastic cover over the emergency release
handle under the window. Push the safety cl ip forward and pull the red
handle fully aft until the window releases. Push the window out and up
until the up-lock brace holds the window up. The door warning light on the
annunciator panel will illuminate if the emergency exit window is not
closed.
CONTROL LOCKS
A control column lock is provided to restrict control column movement.
This restriction holds the ailerons in a neutral position and the elevators
approximately 10° down, thus preventing damage to the control surfaces in
gusty wind conditions.
The rudder is secured with the optional rudder gust lock. To engage the
lock, center the rudder, insure the elevator is fully down. then move the
external rudder lock handle to the lock position. The rudder lock is
disengaged by rotating the external rudder lock handle to the unlock posi-
tion. The rudder lock handle is located above the left horizontal stabili-
zer in the s ide of the fuselage.
If the opt i ana 1 rudder lock is not i n-
stalled, the rudder can be secured by placing an external control surface
lock over the vertical stabilizer and rudder. If neither rudder lock is
available, caster the nosewheel to the full left or right position. This
action will deflect the rudder against its stop, thus restricting rudder
movement.

PROPELLERS
The airplane is equipped with all-metal, three-bladed, constant-speed,
full-feathering, single-acting, governor-regulated propellers. Each pro-
peller util izes oil pressure which opposes the force of springs and coun-
terweights to obtain correct pitch for engine load. Oil pressure from the
propeller governor drives the blades toward low pitch (increasing RPM)
while the springs and counterweights drive blades toward high pitch
