RIGGING THE WINGS

(1) PREPARATION

The aircraft must be level longitudinally and laterally prior to setting or adjusting the
dihedral or the washout angles. Refer to the leveling procedure described in Section
6.3.22.

(2) DIHEDRAL ANGLE

(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
