point that the leg strap would slip on opening. In addition, the webbing at the ring location shows
wear and is replaced at the same time. This procedure is typical for a Flexon and Talon 2 articulated
harness configuration.

2.2 Take the Ty-8 webbing and sew a bowtie fold with the
Ty-4 tape buffer at the 3.50" mark [Figure B].
2.3 Turn the adapter upside down and install the Ty-8 webbing
as shown and glue in place [Figure C].
2.4 Install the bowtie around the ring and glue in place
[Figure D]. The picture shows the inside orientation of
the harness.
2.5 Double check the correct orientation of the hardware [Figure E].
2.6 Mark the stitch pattern [Figure F].
2.7 Sew the webbing with the harness machine in a 4-point W-W pattern [Figure G].
2.8 Reinstall the leg pad. Route the upper pad flap through the adapter from the bottom
[Figure H] and zigzag.
2.9 Fold the bottom pad under and zigzag in place [Figure J].
Note that the ends of the upper and lower pads are offset to
reduce the thickness to be sewn.
3.0 INSPECTION:
3.1 Verify the hardware orientation is correct.
3.2 Verify the stitch pattern is correct.
3.3 The leg pad must be reinstalled correctly.

BACKGROUND. The following steps provide an overview of the procedure to follow.
STEP ONE.
The first thing the rigger must do is to inspect the parachute harness to identify the make and model
and determine the extent of the damage. In some cases, particularly for older designs, it may not be
practical or economically feasible to repair the harness. If the rigger determines that repair is practical,
he/she must then establish a repair plan for the project. There are two reasons for this. One, that
the project is done logically and efficiently. And two, if not having done this type of repair before,
having contacted the manufacturer for guidance, the rigger can explain what he/she intends to do to
effect the repair.
The rigger must make detailed measurements of the harness. Figure A shows a typical harness configuration
and the needed dimensions. On a situation where one side of the harness is intact and can
be used for reference, the rigger still needs dimensions to work against to determine how much
material to order or bill to the job. If both sides of the harness are damaged, great care must be taken
