ELEVATORS

Note: There is a close out tab on the two E-1001A Top Skins and the two E-1001 Bottom skins that must be bent prior to assembling the elevators. AT this point, the top skins are identical and the bottom skins identical. Howe ever, once the tabs are bent in the direction shown in Figure 1, the skins become dedicated left or right. The tabs will make it easier to identify the inside surface skins throughout the building process; they are directed toward the inside of the elevators.

 

Step 1: Remove the vinyl from the skins in the area of the tab. Mark the bend line on the skins as shown in Figure 2.

Step 2: Clamp a skin between the surface of a work bench and a piece of wood with the bend line at the edge of the workbench as shown in Figure 3.

Step 3: Begin forming the bend by hand using a small wood block, Plans called for tapping with flush rivet set, we used a dead blow hammer and it formed very nicely.

Step1: Cleco the E-910 Reinforcement Plates to both E-1002 Front Spars, as shown in Figure 1, then final-drill all the 1/8" Holes common to the spars and plates using a #30 drill.

Mark the plates so that they can be reinstalled in the same position, Remove the plates from the spars and set them aside.

Step2: 

Step 3: Cleco the E-1002 Front Spars to the E-1001B Bottom Skins as shown in Figure 1 (be sure the tabs in the skins are directed as sown). Install the clecos from the skins into the spars.

Step 1: Cleco the E-1008 Ribs (the rib halves should still be clecoed together) and the E-905 Root Rib to the E-1002 Front Spar and to the E-1001B Bottom Skin as shown in Figure 1. Note that, except for the root ribs, the flanges of all the ribs are directed outboard on both elevators. The holes in the front spar used to attach the root ribs are 3/32" while holes for the other ribs are 1/8". This is intentional, so don't be tempted to drill them to match the rest.

Step 2: Cleco the E-1007 Rear Spar to the E-1008 and E-905 Ribs and E-1001B Bottom Skins.

Step 3: Final drill the two holes at the outboard end of the E-1007 Rear Spar the holes that don't match with a rib) using a #30 drill. Final Drill the holes common to the root rib and spars using a #40 drill.
Step 4: Cleco E-1022 Shear Clip to the E-1007 Rear Spar and to the E-1008 Rib shown in Figure 1. The longer flange of the shear clip is positioned inboard of the tab in the E-1001B Skin see Page 9-7) Figure 1) The clecos attaching the shear clip to the rib and spar need to be installed from the inside of the elevator to keep the holes in the longer flange of the shear clip accessible for drilling later
