RIGGING AND ADJUSTMENT OF AILERON CONTROLS. (Refer to Figure 27-10.)
1.  
Check and adjust the rigging of the aileron controls as follows.

— Note —
Adjust and rig flap controls completely before adjusting and rigging aileron controls.

2.  
Check that the control wheels are properly adjusted and in their neutral position. Place the tee bar in the full forward position and maintain in this position by use of a suitable tool.

3.  
Check that both bellcranks are at their neutral positions. The neutral position is obtained when the forward and aft cable connection holes on the bellcrank are an equal distance from the adjacent outboard wing rib.  Rigging tools, as shown in Figure 27-9 may be fabricated to hold the bellcranks in their neutral positions. A snug fit of the tool is required between the bellcrank arms and ribs, which may necessitate loosening a primary or balance cable. Refer to Chapter 91 for tool fabrication details.

4.  
With the aileron control rod connected between the bellcrank and aileron, check that the trailing edge of the aileron is even with the trailing outboard edge of the flaps. This is the aileron neutral position. The ailerons may be allowed to droop by approximately 0.125 of an inch at this point.

5.  
Should the two trailing edges (aileron and flap) not align, disconnect the aileron control push rod from the bellcrank and aileron, loosen the jam nuts at each rod end, and adjust the rod ends to obtain trailing edge alignment. Apply a slight up pressure against the trailing edge of the aileron while making this adjustment. Check that there is sufficient thread engagement at both rod ends.  Any adjustment should be distributed between both rod ends.

6.  
Adjust the primary and balance cable tension as given in Figure 27-10 by the following procedure:

A.  Remove the two front seats if desired, and the bottom of the rear seat to facilitate in the necessary operation.
B.  Loosen the connecting bolts of the idler crossover sprockets at the control tee bar to allow the chain to fit snug around the control wheel sprockets and over the idler sprockets, then tighten bolts.
C.  Ascertain that both bellcranks are at their neutral position.
D.  Adjust the turnbuckles (located in the access opening just aft of the main spar) of the primary and balance cables to their proper cable tension and maintain neutral position of the control wheels. To obtain neutral position of both control wheels, it may also be necessary to adjust the roller chain turnbuckle located between the control wheel sprockets. Finish the adjustment with even tension on all cables and remove any rigging tools.
7.  
Check control operation to insure that the left aileron up and right aileron down stops are contacted simultaneously and vice versa. Adjust the stops as required.

8.  
Rotate the left control wheel in each direction until the bellcranks contact the stops. The sprocket stops on the tee bar should not be contacted until additional “override” movement (cushion) of 0.030 to 0.040 is obtained between the sprocket pin and adjustable stop bolts. (Refer to Figure 27-6.)

9.  
Place the ailerons in the neutral position (aligned with flaps). Check that the up and down travels of each aileron from neutral position is in accordance with specifications given in Figure 27-10. When measuring these travels maintain a light up or down pressure just sufficient to remove the slack between the bellcrank and aileron. Total free play at the aileron trailing edge should not exceed 0.120 of an inch.

10.
Should an out-of-trim condition persist despite all rigging corrections that can be made, there is a possibility that the trailing edge of the aileron has been used to move the aircraft forward. This can result in a slight bulging of the aileron contour at the trailing edge which will cause an out-of-rig con-dition that is very difficult to correct.

RUDDER CONTROL CABLES.
REMOVAL OF RUDDER CONTROL CABLES.  (REFER TO FIGURE 27-11.)

1.  To remove either the forward or aft rudder cables:
A.  Remove the access panel to the aft section of the fuselage.
B.  Disconnect the desired cable at the turnbuckle in the aft section of the fuselage.
2.  To remove either forward rudder cable
A.  Remove the floor panel located directly aft of the main spar by removing the center seats, seat belt attachments and the screws securing the floor panel. Lift the panel and remove from air-plane.
