STITCHING AND RESTITCHING
Perform stitching and restitching as follows, refer to Tables 1 and 2.
1. Parachute canopy assemblies. The stitching and restitching made on parachute canopies should be
accomplished with thread that is contrasting in color to the fabric being restitched. If contrasting color
thread is not available, thread of matching color may be used, providing all other specifications are met.
Straight stitching and restitching on parachute canopy assemblies should be locked by at least 2-
inches at each end of a stitch row, when possible. Zig-Zag stitching does not require locking; however,
zig-zag restitching should extend at least ¼-inch into undamaged stitching at each end, when possible.
When restitching parachute canopy assemblies, stitch directly over the original stitching and follow the
original stitch pattern as closely as possible.
