original construction as possible using a double needle sewing machine, size E nylon thread, and 7
to 11 stitches per inch.

When re-sewing the rib to the new section, pull tension on the top and
bottom skin as required ensuring the rib and the end of the section fits
back into its original place.
The loaded ribs are sewn on top of the ¼-inch seam sewn in step 8., above
(see illustrations known as VIEWs 2 & 5). Ensure that raw edges are not visible.
13. Using the ripstop blocks as a guide, re-sew the non-loaded rib to the center of the section with a
double row of stitching using a double needle sewing machine, size E nylon thread and 7 to 11
stitches per inch (see illustrations known as VIEWs 2 & 5).
14. Fold and sew the loaded ribs with a second double row of straight stitching as shown in the
illustrations known as VIEWs 3 & 6.
15. After sewing the loaded ribs, ensure that all raw edges of the new material are hidden between the
double rows of stitching. Ensure that the stitching cannot be seen on the outside of the canopy both
on the top and bottom skins.
16. If the canopy section is located near the tail, close the tail as required.
17. Re-sew any reinforcement tapes as required.
