Do these steps if you cannot install the rig pins freely, the aileron adjustment and the cable tension is out of tolerance, or a new cable was installed:
(a)
Install rig pins A/S-8 and A/S-9 in the inboard aileron quadrants (Fig. 504).
(b)
Adjust the cables until you get these conditions: 1) The inboard trailing edge corners of the ailerons are set
0.35 to 0.50 inch below the wing trailing edge.
2) The tension of the cables is not more than the specified limits (Fig. 501).
(c)
Remove the all rig pins.
(d)
Operate the ailerons through a minimum of one cycle, with the system at the neutral position when you stop. 1) Make sure the aileron position stays between 0.35 to 0.50
