UPPER AND LOWER ROOT SKINS
22.
The root skins consist of an Upper and Lower Skin.
23.
IMPORTANT: Upper Root Skin orientation is determined by an extra
hole in the FWD Tip side of the skin.
Refer to
FIGURE 05C-23
for
orientation.
24.
The Lower Root Skin has flanges on the Leading and Trailing Edge.
NOTE: There is a left-hand and right-hand as well as a top and bottom
side to the Lower Root Skin.
The Lower Root Skin is positioned such
that the flanges point up as to “envelope” the tank. #40 holes are pre-
located along the root side of the skin which match to Tinnerman
locations in the Root Rib. Refer to
FIGURE 05C-24
for orientation.
25.
Most rivet holes in the Upper and Lower Root Skins are dimpled to
accept countersunk rivets. Some rivet locations must
NOT
be dimpled.
Refer back to
FIGURES 05C-23
and
05C-24
for details.
IMPORTANT:
Be sure the dimpling is done to the correct sides of the Root Skins
.

Rib. Secure the fuel line to the compression tube with a Nylon Tie and
stand-off. Cut fuel line to length as required to connect to the fitting on
the AFT inboard side of the Fuel tank.
