Chapter 5


The first task is to check the line continuity of the canopy. The following method may be used by riggers who do not have access to a canopy hanger. Figure 5-22 shows examples of a seven-cell and nine-cell canopy when viewed from the bottom as by the jumper when in flight. The examples show the line attachment nomenclature referred to in the continuity check. Figure 5-23 shows the standard canopy nomenclature as referred to in the continuity check.


1. First, lay out the canopy on its left side, the slider spanwise with its tape down, and lay out the container with the harness up.

2. If slider bumpers are used, thread one bumper over each riser and down a few inches.

3. Place the slider on the risers spanwise, with its tape facing the canopy.

4. Locate the leading edge and A line attachment. Follow the line 8A (10A) to the outboard side of its link and attach the link to the right riser, finger tight.

5. Pick up line 1A at the canopy attach point. Follow it down to the outboard side of its link and attach the link to the left front riser, finger tight.

6. Turn the container over, harness down, and orient the rear risers to receive their respective links. This simplifies C/D link attachment.

7. Rotate the leading edge under the rest of the canopy. Split the aft section along with its associated control line groups to make the C/D links easily accessible for routing and installation.

8. Locate the data panel at the center cellís upper surface trailing edge. From this center reference point, follow the trailing edge to the left stabilizer and pick up line 1D.

9. Route this line to the outboard side of its link and attach the link to the left rear riser, finger tight.

10. Again from the center reference, follow the trailing edge to the right stabilizer and pick up line 8D (10D).

11. Route this line to the outboard side of its link and attach the link to the right rear riser, finger tight.

12. Return to the center reference point of the trailing edge. Locate and pick up the left side upper control lines consecutively. Verify their continuity to the junction with the lower control line.

13. Removing twists as you go, follow the left lower control line to its running end. Route it through the appropriate slider grommet, and then through the guide ring.

14. Remove the toggle from the riser and route the running end of the lower control line through the toggle attachment loop or grommet.

15. Slide the toggle up to the mark on the control line. Secure it with an overhand knot tied closely to the toggle.

16. The control line attachment for the right side is done in a similar manner.

17. When the control line installation is complete, compare the two toggle settings under equal tension to ensure their uniformity.

18. At this time, verify the continuity of the control line system. Begin at the trailing edge on each side, ensuring that all twists have been removed from the upper and lower control lines. Check that the lower control lines have been properly routed through their appropriate slider grommets and that the toggles have been properly secured equidistant from the trailing edge.

19. Separate the aft section and control line groups to their respective sides and locate the center reference point at the trailing edge.

20. Following the trailing edge control surface outboard will lead the rigger to the left stabilizerís bottom seam and the attachment point of line 1D.

21. Holding D lines 1,2,3, and 4 (1,2,3,4,5) in your right hand and D lines 5,6,7, and 8(6,7,8,9,10) in your left hand, verify the continuity of the C and D lines through the cascades to their respective rear risers.

22. Gather in the control lines and flip the canopy over so the leading edge faces up. Verify this orientation by locating the attachment points of A lines 1 and 8(10).

23. In the same direction you flipped the canopy, rotate the container system harness up.

24. Pick up the front riser groups, follow them to the canopy, and separate.

25. Pick up A lines 8,7,6, and 5 (10, 9,8,7,6). If you have continuous center cell lines, follow the bottom seam down and pick up line 5B (6B). Verify continuity of the A and B lines, through the cascades, to the right front riser.

26. Pick up A lines 1,2,3, and 4 (and 5). If you have continuous center cell lines, follow the bottom seam down and pick up line 4B (5B). Verify continuity through the cascades to the left front riser. The continuity check is now complete.

27. Tighten the connector links with an appropriate size wrench. Do not over tighten! Inspect the links for any marks or damage possibly done during the tightening process. Mark the barrel of the connector links with a telltale mark.

28. Move the slider upward from the risers onto the suspension lines.

29. Move the slider bumpers upwards and into position over the connector links. Hand tack the bumpers in place according to the type used.
