18. Rigging of Aileron Trim
(a) To adjust aileron trim, ensure the following is accomplished either during installation or as a
preadjustment check:
(1.) Trim cables are evenly wrapped (centered) on drums both below control pedestal and in
wing and both cable tumbuckles are located approximately at Wing Station 90.
(2.) Trim drum in wing is centered between stops of trim screw.
(3.) The cable tension is set according to specifications in Figure 502.
(b) Remove access plates on underside of right wing at Stations 171.0 and 176.0.
(c) With trim screw held from rotating, turn trim drum until 0.560 inch exists between forward screw
stop and drum housing measured along screw. (This is neutral position of screw.)
(d) With right wing rigging tool (P/N 72159-2) installed and ailerons in neutral position, rotate trim
wheel in cockpit to specifications in figure 27-6 as indicated on rigging tool. Ensure cable
tension meets specifications in Figure 502.
(e) Ensure rotation of wheel from stop to stop is smooth and free with no binding or chafing.
(f) Using tool (L73035) and a dial type torque wrench, check trim system friction at pedestal by
removing trim wheel and attaching tool and torque wrench to splined shaft. Friction must not
exceed 9 inch-pounds when tested in either direction at any point between limits.
