Parachute Repair Procedure
TITLE: 7.3.7 Main Riser Steering Toggle Velcro® Replacement
NUMBER OF PAGES: 1
APPLICABLE PRODUCTS: Most main risers with a Velcro® toggle installation.
DESCRIPTION: Replacement of the Velcro® toggle keeper on main risers.
AUTHORIZED REPAIRMEN: FAA Senior or Master Parachute Rigger
MATERIALS: E thread
Velcro® of the appropriate width and type
MACHINES: 301 Straight Stitch—Medium Duty 7-11 SPI
EQUIPMENT:
Scissors
Seam ripper or scalpel
Marking pencil
6" ruler
PROCEDURE
NOTE: The term “Velcro®” is used in a generic fashion for hook and loop fastener. While the rigger
should replace the Velcro® to match the original configuration, this installation has proven superior
for its holding ability and the secure line stow configuration.
1.0 DISASSEMBLY:
1.1 Mark the location of the old Velcro® [Figure A].
1.2 Remove the old Velcro®.
2.0 REASSEMBLY:
2.1 Cut a new piece(s) of Velcro® to match the original.
2.2 Position the Velcro® to the original location.
2.3 Sew the hook Velcro® with a single needle machine.
Sew an additional row of stitching down the center of the Velcro® [Figure B]. This keeps the
center from lifting during use and tearing out the edge stitching.
2.4 Position the loop line
stow Velcro® to match the
hook and sew along the
edge, overstitching the
ends [Figure C].
3.0 INSPECTION:
3.1 Check that the location of
Velcro® is the same as the
original.
3.2 Check stitch patterns and center stitching.

Accessory components are comprised of the reserve pilot
chute, reserve deployment bag or device, main deployment
bag, main pilot chute and bridle, main and reserve
toggles, reserve static line (RSL) lanyard, 3-ring release
handle, and reserve ripcord.
The reserve components generally do not suffer much
wear due to their infrequent use. In addition, with their
frequent inspection during the repack cycle, any necessary
repairs become obvious and are taken care of before
they become major problems.
1. Metal ripcords usually are not repairable and must be
replaced when they are damaged.
2. Reserve pilot chutes experience torn mesh, minor
canopy damage, broken hand tackings, and damaged
grommets in the cap.
The reserve free bag may have the grommets in the closing
flap pull out of the material. The high-drag bridle is a
critical area and is usually not repairable.
The RSL lanyard is another critical item that is usually
not repairable, except for the replacement of a defective
snap shackle.
Main components, on the other hand, are subject to extensive
wear and tear. Most jumpers do not take time to
inspect their main components on a regular basis and generally
operate on a “repair as broken” basis. By the time
the rigger sees the components, it is easier and more cost
effective to replace than to repair them. However, there
are regular wear trends that the rigger can make their customers
aware of so they can look for them and have them
taken care of.
7.4 The following are repairs to accessory components,
found in Section 4 of this chapter.
7.4.1 Reserve pilot chute repair—Mesh, tackings,
and bad grommet
7.4.2 Reserve free bag repair—Grommet pullout
7.4.3 Main pilot chute repair—Top canopy

7.4.4 Main pilot chute collapsible bridle replacement
