## Inspection 

• 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. 

## Square Canopy—Pilot Chute Attachment Point Repair 

• 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 

## Procedure 

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. 

## Disassembly 

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.
