ENTRANCE DOORS AND CABIN WINDOWS
Entry to, and exit from the airplane is accomplished through either of two entry doors, one on each side of the cabin at the front seat positions (refer to Section 6 for cabin and cabin door dimensions). The doors incorporate a recessed exterior door handle, a conventional interior door handle, a key-operated door lock (left door only), a door stop mechanism, and an openable window in the left door. An openable right door window is also available.
To open the doors from outside the airplane, utilize the recessed door handle near the aft edge of either door by grasping the forward edge of the handle and pulling outboard. To close or open the doors from inside the airplane, use the combination door handle and arm rest. The inside door handle has three positions and a placard at its base which reads OPEN, CLOSE, and LOCK. The handle is spring-loaded to the CLOSE (up) position. When the door has been pulled shut and latched, lock it by rotating the door handle forward to the LOCK position (flush with the am rest). When the handle is rotated to the LOCK position, an over-center action will hold it in that position. Both cabin doors should be locked prior to flight, and should not be opened intentionally during flight.
The left cabin door is equipped
with an openable window which is held in the closed position by a detent
equipped latch on the lower edge of the window frame. To open the window, rotate
the latch upward. The window is equipped with a spring-loaded retaining arm
which will help rotate the window outward and hold it there. An openable window
is also available for the right door, and functions in the same manner as the
left window. If required, either window may be opened at any speed up to 164
KIAS. The cabin top windows (if installed), rear side windows, and rear window
are of the fixed type and cannot be opened.
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 with a red metal flag attached to it. The flag is labeled CONTROL
LOCK, REMOVE BEFORE STARTING 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 red 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.
