MAINTENANCE MANUAL
GENERAL
1. Description and Operation
The airplane is controlled in flight by the use of three primary control surfaces, consisting of ailerons,
elevator and rudder. Operation of these controls is through movement of the dual control wheels and
rudder pedals. On the forward end of each control wheel is a quadrant assembly to which the aileron
control cables are fastened. Also connected to the control wheel push-pull tubes are interconnect arms
to the elevator torque tube located behind the instrument panel. Mounted on this torque tube are sectors
to which the elevator control cables are fastened; thus the forward and aft movement of the control
wheels in turn moves the torque tube and sectors thus transmitting movement thru the control cables to
the elevator.
The rudder controls are driven from dual rudder pedals through torque tubes which have dual sectors
connected and control cables from these sectors to the rudder sector located in the aircraft tail section.
Provisions for elevator and rudder trim are provided by adjustable trim mechanisms. The trim controls
and indicators are in the pedestal located on the instrument panel. Elevator trim is through cables routed
to the elevator trim screw located in the tail cone which drives dual actuators to the trim tab. The rudder
trim is controlled by a trim wheel and screw assembly connected to a bungee assembly connected to the
rudder torque tube behind the instrument panel.
The ailerons and rudder are interconnected through a spring system which is activated only when
controls are out of harmony. In normal coordinated flight it is inactive.
2. Standard Practices and Procedures
Tips for the removal, installation and rigging of the various assemblies:
A. It is recommended, though not always necessary, to level and place the airplane on jacks during
rigging and adjustment.
B. Remove turnbuckle barrels from cable ends before withdrawing the cables through the structures.
C. Tie a cord to the cable end before withdrawing the cable through the structures to facilitate
installation of cable.
D. When referring to marking cable end, etc., before disconnecting, use a felt tip marking pen.
E. Assemble and adjust the turnbuckles so that each terminal is screwed an approximately equal
distance into the barrel. Do not turn the terminals in such a manner that will put a permanent “twist”
into the cables.
F. Cable tensions should be taken with the appropriate control surface in its neutral position.
G. After completion of each adjustment, check the turnbuckles to be sure not more than three terminal
threads are visible outside the barrel. Install the locking clips, and check for proper installation by
trying to remove the clips using fingers only. Both locking clips may be installed in opposite holes.
Locking clips which have been installed and removed must be scrapped and not reused.
Turnbuckles may be safetied in accordance with Advisory Circular 43.13-1, latest revision.
H. When pushrods or rod ends are provided with an inspection hole, the screw must be screwed in far
enough to pass the inspection hole. This can be determined visually or by feel, inserting a piece of
wire into the inspection hole. If no hole is provided, there must be a minimum of .375 of an inch
thread engagement.
I. When installing rod end jamnuts, refer to 20-00-00, Figure 2, for proper installation method.
