| Step 1:
Trim flange material (shaded areas)
from opposite ends of the two VS-1014 Rear Spar Caps using the
dimensions (which apply to both spar caps) in Figure 1. Make sure to
trim the material from the longer of the two flanges. (When marking the
parts for trimming, clamp them
to a table or back to back to remove the bow in the parts.) Once trimmed
the spar caps become dedicated left and right parts (VS-1014-L
and VS-1014-R respectively) as labeled in the figure. Deburr (Section
5B) the edges of both spar caps to prevent them from scratching mating
parts. Note: Deburr and clear away chips at all appropriate stages 09/23/07 |

| Step: 2
Nest the VS-1014-L & -R Rear Spar Caps into the corners of the VS-1003
Rear Spar as shown in Figure 2. Note that the
trimmed flange of the rear spar caps
fits against the web of the rear spar. Flush the bottom of the rear spar
caps with the bottom edge of the spar flanges then clamp them in
place along the spar flange.
Starting from the bottom of the spar, match-drill about every fourth hole of the rear spar web into the spar caps using a 1/8" drill (ignore the 3/16" upper attach bolt holes; these holes are drilled in Step 5). Cleco each hole as you drill and be sure to drill perpendicular to the spar web, particularly any holes common to the VS-1010 and VS-1011 Bottom and Middle Rudder Hinge Brackets. After reaching the top of the spar caps, go back with the same drill and match-drill the remaining 1/8" holes of the rear spar web into the spar caps. Remove the spar caps and deburr the holes. Clear away any chips, then cleco the rear spar caps back in place 09/23/07 |

| Step: 3
Match-Drill the flange holes of the
VS-1003 Rear Spar into the VS-1014-L and -R Rear Spar Caps using
a #40 drill, deco as you go. Once again, remove the spar caps and deburr the holes. Clear away any chips, then cleco the rear spar caps back in place 09/23/07 |

| Step: 4 Deburr
the edges of the VS-1008 Rear Spar Doubler. Cleco the doubler,
the VS-1014-L and -R Spar Caps, the VS-1010 Bottom Rudder Hinge
Brackets, and the VS-1011 Middle Rudder Hinge Brackets to the VS-1003
Rear Spar as
shown in Figure 2. Cleco the VS-1012 Top Rudder Hinge Brackets and the
VS-1017 Hinge Doubler in place. With all the parts clecoed together, use a #30 drill to final-drill the holes of the top, middle, and bottom rudder hinge brackets, the hinge doubler, and all the 1/8" holes of the spar doubler and spar caps. 09/23/07 |

Step: 5 Match-Drill the upper attach bolt holes of the VS-1003 Rear Spar and VS-1008 Rear Spar Doubler into the VS-1014-L and -R Spar Caps using a 3/16" drill. Don't final-drill these holes to size (#12) yet; this is done when the vertical stabilizer is fitted to the tailcone. 09/23/07 |
 |
|||||||||||||
| Step: 6:
Machine countersink (Section 5E) all of the #30 holes
on the forward side of the VS-1008 Spar Doubler, below the
upper attach
bolt holes, for 1/8" flush rivets. 09/30/07 |
