Parachute Repair Procedure
TITLE: 7.3.2 Lower Leg Strap Shortening
NUMBER OF PAGES: 2
APPLICABLE PRODUCTS: All harness configurations.
DESCRIPTION: Shortening of the lower leg straps.
AUTHORIZED REPAIRMEN: FAA Master Parachute Rigger
MATERIALS: 5-cord nylon thread—color to match original
MACHINES: Heavy-duty harness machine—Singer 7-33 or equivalent 5-7 SPI
EQUIPMENT:
Seam ripper or scalpel
Marking pencil
Ruler
Hot knife
PROCEDURE
Note: The shortening of the leg strap, while a relatively straightforward process, is an extremely
important procedure. If done improperly, it could result in the harness fitting improperly or the leg
straps to come unthreaded and the user to fall out during opening.
1.0 DISASSEMBLY:
1.1 If the leg strap is of the thread-thru configuration, unthread the webbing from the leg adapter.
If the leg strap has an adjustable “V” ring used in conjunction with a snap, disconnect the
“V” ring from the snap. Lay the leg strap out flat.
1.2 Remove the harness stitching from the rolled end of the webbing.
1.3 Measure the required distance from the end of the
strap that is required for shortening and mark
accordingly [Figure A].
1.4 Trim the webbing at the mark using the hot knife.
2.0 REASSEMBLY:
2.1 For the thread-thru configuration, place a mark at
3.50" from the end of the webbing on the bottom of
the webbing [Figure B]. This will be the “fold to”
mark for the first fold of the webbing. Fold one more time for a total of three layers of webbing
[Figure C].
2.2 Sew the rolled stop end according to Figure D with the harness machine.

7-64
2.3 For the “V” ring configuration, place a mark at 2.00" from the top end of the webbing. This
will also be the “fold to” mark for the first fold. Make two additional folds for a total of four
layers.
2.4 Sew the rolled stop end according to Figure E
with the harness machine.
3.0 INSPECTION:
3.1 Check the stitching for the correct pattern and
thread tension.
3.2 For the thread-thru configuration, make sure there is no twist to the leg strap and thread the
webbing through the leg adapter. The rolled end should face outward.
3.3 For the “V” ring configuration, connect the “V” ring to the snap. The rolled stop end should
also face outward.
