ARMY TM 10-1670-281-23&P AIR FORCE T.O. 13C5-32-2 NAVY NAVAIR 13-1-32 4839-152 Figure 2-151.  Forming Riser Clevis Safety Pin.   (4)  Bridle line. (a)  Restitching.  Stitch and restitch broken or loose stitching using a zig-zag sewing machine with size E nylon thread which matches the color of the original stitching, when possible.  Restitch by  overstitching  each  end  of  the  stitch  formation  by  1/2  inch.    Restitch  directly  over  the original stitching, following the original stitch pattern as closely as possible. (b)  Replacement.  Replace an unserviceable bridle line by fabricating as follows: 1  Remove the bridle line from the inner loop within the static line pilot parachute bag by untieing the knot securing the line to the loop. 2  Cut a 22-inch length of type IV coreless nylon cord and taper-cut 1/2 inch of each end. 3  Using a suitable marking aid, mark the cord length at points 2 1/2, 5 1/2, and 8 1/2 inches from one end, and 2 1/2 and 10 1/2 inches from the opposite end. 4  Insert a suitable splicing aid into the cord casing at the 8 1/2-inch mark and work the splicing aid through the cord casing to the outside at the 5 1/2-inch mark. 5  Attach the nearest tapered cord end to the splicing aid and pull the aid back through the cord casing until the 2 1/2- and 5 1/2-inch marks are alined and a 1 1/2-inch long loop is formed (figure 2-152). 6    Hold  the  alined  marks  together  and  continue  pulling  the  splicing  aid  back  through  the  cord casing  to  the  outside  at  the  8  1/2-inch  mark,  allowing  only  the  cord  tapered  end  to  protrude from the cord casing. 7  Remove the cord tapered end from the splicing aid.  While holding the alined marks, stretch the cord length to permit the tapered end to recede into the cord casing. 8  Reinsert the splicing aid into the cord casing at the 8 1/2-inch mark and work the splicing aid through the cord casing to the outside at the 10 1/2-inch mark. 2-211
