Completed step 5 page 20iS/U-04. Riveted F-1204T-L and F-1204U-L to F-01204-1 as shown in Figure 5. Repeaedt for the right side Completed steps 1-9 and 12 page 20iS/U-05. Step 1: Riveted F-1204P-L & -R to F-01204-1 as shown in Figure 1. Step 2: Riveted F-01204F-L-1 & -R-1 to F-01204D-1. For now, riveted only the bottom eight holes in F-01204F-L-1 & -R-1 per the call-out. Refer Page 20iS-06 for rivet call-outs. Step 3: Clecoed F-01204D-1 to F-01204-1, (except at F-01204F-L-1 & -R-1), and clecoed both F-01204J, F-01204G-L & -R, F-1205A, and two F-01205B-1 to the F-01204-1 assembly as shown in Figure 1 (for rigidity). Refer Figure 2 for the position of F-1205A on F-01204-1. Step 4: Clamped F-01204G-L & -R to F-01204-1 using a C-clamp and a small block of wood held in the footprint of the rivet pattern on the fwd side of the F-01204G-L & -R. Step 5: Final-Drilled #30 F-01204G-L & -R in three to four places using F-01204-1 (and F-01204F-L-1 & -R-1) as a guide. Step 12: Machine countersunk #30 the four holes near the centerline of F-01204D-1 to 100° per the Figure 1 call-out.
