Inspection Square Canopy—Pilot Chute Attachment Point  Repair Disassembly Procedure 11. Trim the top and bottom edges as marked.  [Figure N] •  Seam alignment should be straight. •  Check the tension of the replaced rib material. •  Make sure the seams are restitched correctly. •  Verify that the crossport is cut correctly. •  The line attachment tape must be replaced correctly  with no twists in the suspension line. 12. Pin the top seam back onto the top panel. Sew in place  with either the single needle or if available, with the  double needle machine and puller.  [Figure O]  Repeat  with the bottom seam. •  Applicable Products: Square main canopies •  Description: Repair of the main canopy pilot chute  attachment point. •  Authorized Repairmen: FAA Master Parachute Rigger  •  Materials: E thread; fabric—type and color to match,  reinforcing tape—type and color to match, reinforcing  fabric—type and color to match •  Machines: 301 straight stitch—medium duty 7–11  SPI, 308 zigzag—medium duty 7–11 SPI, 1 inch ×  42 stitch bar tack •  Equipment: Scissors, seam ripper, marking pencil,  and 12–inch ruler 1.  Inspect the area to determine the extent of the damage.  [Figure A]  If the stitching that holds the attachment  point to the canopy is simply coming loose, re-stitch  as per the original. 13. Inspect finished work.  [Figure P] This repair is quite common. If the canopy is inspected  regularly, the beginnings of the damage will be noticed and  a simple re-stitching will solve the problem. However, many  times it is not and the resultant damage is quite extensive  requiring repair of the rib, as well as the top panel. 7-28
