ARMY TM 10-1670-281-23&P AIR FORCE T.O. 13C5-32-2 NAVY NAVAIR 13-1-32 (l)  Moving to the connector link, hold replacement line and adjacent line tightly together at link and trace both lines from link to canopy skirt under equal tension.  Mark new line where lines reach  lower  edge  of  lower  lateral  band  (figure  2-114).    Check  correctness  of  marking  by again applying equal tension on both lines. (m)    Hold  adjacent  line  and  new  line  together  at  lower  lateral  band,  grasp  both  lines  at  upper lateral  band,  and  apply  equal  tension  to  both  lines.    Mark  new  line  at  upper  edge  of  upper lateral band.  Check correctness of marking. (n)  Aline the mark made in (m), above, with the upper edge of the upper lateral band.  Secure the cord to the radial seam with temporary tacking or push pins.  Cut the cord even with the upper edge of the upper lateral band. (o)    Position   the   loose   end   of   the   applicable   vent   line   alongside   the   new   suspension   line positioned in (m), above, so that the end of the vent line is 6 inches below the upper edge of the upper lateral band. Secure in place with temporary tacking or push pins.  Ensure that the vent line passes through the bridle loop before being secured to the radial seam. (p) Cut a 6-inch length of 9/16-inch wide, type I nylon webbing and wax each webbing end 1/4 inch. (q)  Place the 6-inch long webbing lengthwise on the inside of the affected radial seam with the upper end of the webbing length alined with the upper edge of the upper lateral band.  Insure the  webbing  length  is  centered  on  the  respective  radial  line  and  positioned  vent  line  end. Secure the webbing length with temporary tacking or pushpins. (r)  Working on the canopy outside, secure the positioned end of the vent line to the applicable radial  seam  and  6-inch  webbing  length  by  stitching  a  3/16-inch  wide  row  of  double-throw zigzag stitching from a point 1/4 inch above the upper lateral band to the lower edge of the applicable vent line end. Stitching will be made using a medium-duty sewing machine, size E nylon thread, 7 to 11 stitches per inch. (s)    Beginning  6  inches  below  the  upper  edge  of  the  upper  lateral  band,  secure  the  radial  line upper  end  to  the  radial  seam  and  6-inch  webbing  length  by  stitching  a  6-inch  long  row  of 3/16-inch wide double throw zigzag stitching to the upper edge.  Stitching will be made using a  medium-duty  sewing  machine,  size  E  nylon  thread,  7  to  11  stitches  per  inch.    Remove temporary tacking or pushpins installed in steps (n), (o) and (q), above. (t)  Reinstall the upper, intermediate and lower seam reinforcement tapes removed in (e), above, by restitching according to original construction details and paragraph 2-28, below.  Stitching will be made using a medium-duty sewing machine, size E nylon thread, 7 to 11 stitches per inch. (u)  Aline mark on new line with lower edge of lower lateral band and sew new line to canopy at all  attaching  points  in  accordance  with  figure  2-114.    Use  a  medium-duty  sewing  machine and size E nylon thread, 7 to 11 stitches per inch. (v)  Aline mark on line with inside edge of link assembly and tie line to link in accordance with figure 2-114. 2-139
