Step 1: Press the two SB625-7 Snap Bushings into the 5/8" holes in the front spar assembly as shown in Figure 1.

Step 2: Cleco the inspar Rib, stringer, and stringer web assembly (riveted on the previous page) into position on the front spar assembly. Do not rivet the assembly in place at this time since it shares rivets with two nose ribs.

 

Step 3: Except for the out board HS-904 Inspar Ribs (see figure 1), cleco the remaining inspar ribs to the front spar assembly. Slide the HS-1004 Inspar Ribs along the stringers to get them into position.

Rivet these ribs in place using the rivets called out in the figure. The rivets called out in the blow up apply to all the HS-1004 inspar ribs except for the inboard two.
