| Step 1:
Deburr the edges of all remaining parts to prevent scratching during
fitting. 09/30/07 |
 |
| Step 2:
As shown in Figure 1,Cceco together all the parts of the
vertical stabilizer skeleton: the rear spar assembly, the VS-1006 Top
Rib, the VS-1004 and VS-1007 inspar Ribs, the VS-1002 Front Spar, and
the VS-1005 and VS-1013 Nose Ribs.
Final-Drill all the holes common to the parts
in the skeleton using a #30 drill.

| Step 3:
Remove the vinyl from the inside surface of the VS-1001 Stab Skin then cleco
it to the frame work as shown in Figure 2
09/30/07 |
 |
| Step 4: Final-Drill all
the holes common to the skin and skeleton with a #40 drill, then remove
the skin from the skeleton and deburr the holes. |
|
| Step 5: Empennage
fairing screw holes are indicated on page 6-6, Figure 1, along the
bottom edge of the depicted skin. Mark the corresponding holes in the
VS-1001 Vertical Stab Skin, and in the flanges of the VS-1005 Bottom
Nose Rib, the VS-1004 Bottom Inspar Rib, and the VS-1003 Rear Spar. |
|
| Step 6: Dimple all the
holes of the VS-101 Vertical Stab Skin except for the following: the
eight vertical stab tip faring attachment holes at the top of the skin
(see Page 06-06, Figure 1) and the holes just marked in Step 5.
Depending on the vintage of your "C" frame tool, you may not be able to
reach all of the holes to dimple. The unreachable holes can be dimpled
with a pop rivet dimple die set available from tool suppliers. |
|
| Step 7: Remove the ribs
from the front and rear spars then deburr all of the holes. Except for
the holes marked in step 5, dimple all of the rib side flange holes
(including the hole in the small tabs at the front of the VS-1004 and
VS-1007 Inspar ribs). |
|
| Step 8: Machine
countersink (Section 5E) the flange holes in the VS-1003 Rear Spar which
are common to the VS-1001 Vertical Stab Skin and to the VS-1014-L
and VS-1014-R Rear Spar Caps (see note along the side of Figure 2). Do
not, however, countersink the holes in the spar (located at the bottom
of the skin) which were marked in step 5. The countersink should be deep
enough to accept the dimple of the skin. Leave the spar caps clecoed in
place during this operation. |
|
| Step 9: Disassemble the
rear spar assembly and deburr all holes. Be sure to mark (Section 5C)
the rudder hinge brackets as they are removed so they can be reinstalled
in the same position as drilled. |
|
| Step 10: Dimple the
flange holes of the VS-1003 Rear Spar above the machine countersunk
holes. |
|
| Step 11: Final-Drill
with a #12 drill the single 3/16" hole in each of the VS-1010 Bottom,
VS-1011 Middle and VS-1012 Top Rudder Hinge Brackets. Deburr the holes. |
