Step 5: Attached the F-01276C-1 Systems Blocks and F-01276E Systems Block Stiffeners to the screws in the F-01276-1 Bottom Skin as shown in the detail view of Figure 2.
Completed step 1 psge 29iS/U-03
Step 1: Dimpled the F-1201P to make the F-1201P-L & -R. Dimpled the corresponding screw holes in the F-01201A-1 first, then dimpled the rivet holes in the F-01201A-1 per Detail A.
Completed steps 1-6 page 29iS/U-05
Step 1: Separated the F-1202M as shown in Figure 1. Step 2: Separated the F-01201Q-1 as shown in Figure 2. Step 3: Machine countersunk #40 and attached nutplates to the F-01201Q-L-1 & -R-1 as shown in Figure 2. Step 4: Separated the F-1202D, then dimpled the F-01202D-L & -R as shown in Figure 3 Step 5: Separated the F-01202C as shown in Figure 4.
Completed steps 1-8 page 29iS/U-06 Step 1: Cut two pieces of AA6-125X1X1 angle and mark as shown in Figure 1. Step 2: Fabricated the F-1202Y by match-drillied the holes in the F-1202H-L & -R into the angles as shown in Figure 2. Aligned the centerline marks with the nutplate screw holes and ensured that the bottom surfaces of the parts are in the same plane Step 3: Machine countersunk the rivet holes in the F-1202M-L flush on the outboard side that correspond to the web of the F-1202H-L as shown. Step 4: Machine countersunk #40 the rivet holes in the upper and aft flanges of the F-1202H-L. Step 5: Dimpleg the rivet holes in the web of the F-1202H-L that correspond to the F-1202M-L flush on the outboard side. Step 6: Final-Drilled #17, deburr, then dimpled the nutplate screw holes in the upper flanges of the F-1202H-L. Step 7: Cleco the F-1202M-L and F-1202Y to the F-1202H-L. Step 8: Final-Drill 1/4 the forward nutplate screw hole as shown. Remove the clecos and deburr
Step 6: Dimpled the rivet hole in the F-01202C-L as shown in Figure 4.
