Step 1:   Flute and straighten all ribs per Section 5N

Note: I am putting just a light flute in the ribs, looking down the line and try to straighten them a little. It is hard to tell how much is required now because of the notches in the ribs. From experience on the RV7 fine tuning the fluting is required when you begin to fit the skin to the ribs, especially on the leading edges and tanks. You will need to put the ribs in and out and make adjustments so the holes line up and not use force to bring things into alignment. You will find that fluting is a fine art and takes some time to gain experience.

Step 2:  Cut a piece of AA6-063X3/4X3/4, 7 13/16 inches long as shown in Figure 1.

Step 3:  Cut a piece of .063 2024-T3 Alclad and mark the alignment lines per the dimensions in Figure 2.

Step 4:   Cut a piece of .063 2024-T3 ALCLAD and mark the dimension in Figure 3.

Step 5:  Clamp W-1029A-L Torque Tube Support Bracket, W-1029D Spacer and W-1029E Spacer together with the centerlines drawn in steps 2 and 3 aligned with the holes n the support bracket s shown in Figure 4. Match-Drill the spacers #30 using the torque tube support bracket as a drill guide.

Step 6: Cleco the VA-146 Flange Bearing in between the W-1029A-L and W-1029B-L Torque Tube Support Brackets. Cleco the assembly to the upper and lower flanges of the W-1010-R Inboard Wing Rib as shown in Figure 5. (The support brackets Cleco into the forth and fifth holes back from the front of the main flange not counting the tab.) Clamp the W-1029C Angle flush against the aft face of the W-1029B-L Torque Tube Support Bracket and the inboard face of the inboard wing rib.

Step 7: Match-Drill #30 and Cleco the W-1010-R Inboard Wing Rib to the W-1029C Angle using the holes in the rib as a drill guide.

Step 8: March-Drill and Cleco the W-1029A-L and W-1029B-L Torque Tube Support Brackets to the W-1029C Angle at two attach points using the support brackets as drill guide. Use a right angle drill or extension bit for best results.

Match Drill the holes common between the torque tube support brackets and the VA-146 Flange bearing. Disassemble all the parts from the inboard wing rib. Cleco the W-1029B-L Torque Tube Support Bracket to the angle at the two location just drilled and Match-Drill #30 the remaining attach holes.

Step 9:  Cleco the W-1025B-L Flap Hinge Rib and W-1025A Flap Hinge Bracket to the W-1010-R Inboard Rib as shown in Figure 7. Final-Drill all common attach holes in the assembly to #30.

Step 10:  Cleco the W-1025B-R Flap Hinge Rib and W-1025A Flap Hinge Bracket to the two alignment holes in the W-1011-L Inboard Wing Rib as shown in Figure 8. March-Drill #30 the inboard wing rib using the holes in the flap hinge rib and bracket as a drill guide. Final-Drill #30 the two alignment holes.  Repeat this process to create two assemblies as shown in Figure 8.
