Step 1: Cleco the left and right front spar assemblies to the E-1008 Ribs and E-1001 Skins as shown in Figure 1.

Step 2: Rivet the E-1002 Front Spar to the forward E-1008 Rib Flanges using the rivets called out in the figure.

Step 3: Place the elevators on a flat work surface with the clecos securing the E-1001 Skins to the E-1002 Front Spars hanging over the edge. Rivet the Skins to the spars using the rivets shown on Page 9-20, Figures  1 & 2. For the time being, however, leave out the rivets in the spar flanges outboard most E-1008 Rib and inboard of the inboard most rib. Not installing these rivets leaves the outboard and inboard sections of the elevators accessible for riveting the E-903 and 904 Tips Ribs and the E-921 Elevator Gusset.

Step 1: Rivet the aft flange of the E-905 Root Rib to the E-1007 Rear Spar using the rivets shown in Figure 1.

Step 2: Remove clecos and lift the corner of one of the E-1001 Skins to gain access to the E-921 Elevator Gusset (Not visible in figure) Using the rivets shown, rivet the gusset to the root rib.

Step 3: On this end of the elevator, rivet the E-1001 Skins to the flanges of the E-905 Root Rib and E-1002 Front Spar using the rivets shown on page 9-20, Figures 1 & 2.

Step 4: Cleco the Rib Tip assembly to the elevator, then rivet the assembly to the E-1022 Shear clip using the rivets called out in the figure. Access to the clip can be gained from between the skins of the trailing edge.

Step 5: Remove the clecos required to lift the corner of the E-1001B Bottom Skin to gain access to the back of the E-1002 Front Spar. Rivet the tip rib assembly to the front spar using the rivets shown in the Figure.

Step 6: The rivets used in this step can be found on Page 9-20, Figures 1 & 2. Rivet the E-1000 Top Skin to the flange of the E-1002 Front Spar.

 Rivet the Skin to the E-1013 Counterbalance skin and the flange of the E-903 Outboard tip rib. Don't rivet the flange of  the counterbalance skin and elevator skin (the same holes that blind rivets are called for in the figure for the E-1001B Bottom Skin) can be accessed in the E-1001 Top Skin for solid riveting at this point.

Repeat this step for riveting the E-1001B Bottom Skin to the front spar and tip assembly. Remember not to rivet the skin to the outboard tip rib aft of the rear spar. The two holes that call for blind rivets in the figure, will need to be drilled with a 7/16" drill.
