S-4 Closeout - Rans N512DT Text Manual

RANS S-21 OUTBOUND
1. Trim the S-4 closeout to the outside edge of the trim lines on the top corners.
2. Trim the top middle section and the bottom edges to leave a 1/8" flange for
rigidity.
3. Trim the corners for clearance around the window support angles.
4. Cut Spacers from provided stock per FIGURE 07-07A. Glue the (2) spacers to
the back side of the S-4 closeout at the marker divots in the S-4 closeout. Drill
#11 from the bushings through the closeout.
5. Test fit the S-4 closeout and note where trimming is needed to fit the curvature of
the top corners to the tailcone top skin.
6. Trim conservatively and test fit. Repeat until satisfied with fit.
7. Transfer drill #11, through the Closeout at the bushing locations into the S-4
bulkhead. Remove the S-4 closeout and drill the locations for nut plates and rivet
them in place.
8. Locate and drill (4) #11 holes in the aft section of the baggage floor where the S-
4 closeout overlaps and forward of the S-4 bulkhead flange. It is not necessary to
locate these holes in the bulkhead flange, as it is not pressed all the way to 90°,
which causes problems.
9. Drill (2) additional holes just above the baggage floor into the baggage side
panels.
10. Drill these (6) locations for nut plates and rivet nut plates in place.
11. Reinstall the S-4 Closeout. Use a hole finder to transfer drill the (6) holes to the

S-4 Closeout.
