WING INSTALLATION
(See Figures 7-11 through 7-14)
To install the wings, proceed as follows
using all new nuts, tube nuts, bolts and
washers:
* NOTE *
Coat all bolt shanks with Snap-
On™ General Purpose Anti-
seize lubricant, or equivalent,
prior to installing. Be careful,
however, not to get anti-seize
on bolt threads, as this
invalidates torque readings.
A. If the landing gear is not installed,
support the fuselage at a convenient
height using jacks at the landing gear
attach points, left and right, and at
the aft jack point.
B. On the left wing, install the outboard
wing attach angle on the main spar
web with NAS1104-16 bolts, ¼ inch
AN960 and MS20002C washers and
MS21042 nuts. Torque the nuts per
Table 7-3, six places.
Figure 7-11: Wing Spar Inboard End and Splice Plates
On all NAS bolts described
hereinafter, insure that at
least two bolt threads are
showing beyond the edge of
the fiber locknut and that the
nut has not bottomed-out on
the bolt threads.
C. On the left wing, install the center
splice plate if removed, to the spar
web and install the 3/16” and ¼”
bolts and c/s screws, AN960 and
MS20002C washers and MS21042
nuts per Figure 7-12. Torque the
nuts per Table 7-3, 152 places.
