Washout Angle - Cub Crafters CC11-100 Maintenance Manual

(a) Remove the front wing root fairings.
(b) Stretch a string from wing tip to wing tip above the front spar and pull tight and
secure.
(c) Measure down from the string to the top of the inboard edge of the front spar cap
(Figure 6.3.4.2). The measurement should be 3 inches plus or minus 0.13 (1/8)
inches. This adjustment is accomplished by turning the forks in or out. However,
prior to making any adjustment, proceed to step (d) and (e).
(d) To determine that each wing panel has the same dihedral, hold a straightedge on
the end of a 30-inch level so that one end of the straightedge protrudes 0.41
(13/32) of an inch above the level (see Figure 6.3.4.2). Place the level
combination along the front spar bottom between the lift strut and jury strut
attachment fittings as illustrated in Figure 6.3.4.2. The bubble should be
approximately centered. Check the opposite wing panel in the same manner.
(e) If the dihedral angle is not equal for both wing panels, adjust the threaded fork on
the lower end of the front strut until the dihedral angle is the same. Recheck the
total dihedral and readjust as necessary.
(f) Record the actual results in the aircraft logbook.

(3) WASHOUT ANGLE

(a) Check the washout of each wing by holding a straightedge on the end of a 30-
inch level so that one end of the straightedge protrudes 0.38 (3/8) inches above
the level (See Figure 6.3.4.2
of the full rib next to the outboard end of the aileron. The level end with
straightedge space should fit to the rear of the rib while the other end of the level
should be placed under the front spar.
(b) To obtain the proper washout, adjust the threaded fork at the lower end of the
rear strut at the fuselage end until the bubble is centered.
(c) Repeat on the opposite wing if needed.
(d) Record the actual results in the aircraft logbook.
There should not be more than 15 threads exposed on the lift strut forks.
