REPLACE
Replace an unserviceable control line by fabricating as follows:
1. Place the canopy in proper layout on a repair surface and apply partial tension to the suspension lines.
2. Trace the applicable control line from the toggle to the control line bridle.
3. Remove the toggle from the control line bottom end.
4. Cut and remove the control line top end from the reefing ring through which the control line bridle
passes.
5. Cut a 28½-foot length of type II, nylon cord, for use as a control line and wax the ends.
6. Make a mark at a point 4½-inches from one end of the cord length. Make a second mark at a point
1¼-inches above the first mark.
7. Pass the marked end of the cord length through the original control line reefing ring, located on the
control line bridle, until the reefing ring is located between the two marks. Fold the cord length
marked end back and align the two marks.
