Diagonal cutters
PROCEDURE
Note: The canopy fabric portion of a reserve pilot chute would be repaired as necessary with similar
patching techniques as used on a canopy. The mesh portion, however, may be subject to different
techniques. Another area of common damage is the thru grommet in the top of the pilot chute. The
following procedure describes the replacement of the grommet in the top of the pilot chute. Figure A
shows a damaged grommet.
1.0 DISASSEMBLY: Grommet replacement.
1.1 Remove the hand tackings used to secure the base of the
pilot chute to the spring [Figure B].
1.2 Turn the pilot chute upside down and push the canopy
down until the grommet is exposed [Figure C].
1.3 Using diagonal cutters, remove the damaged grommet
being careful not to damage the fabric of the cap [Figure D].
7-82
2.0 REASSEMBLY:
2.1 Using the handset, set a new grommet. Be careful not to catch any fabric during the process
[Figure E].
2.2 Reposition the canopy over the spring. Grasp the skirt at the bottom end of the spring. Make
sure that the radial tapes run directly from the bottom to the cap in a straight line [Figure F].
If the tapes “barberpole” around the spring, the pilot chute may not inflate properly on
launch.
2.3 Hand tack the bottom of the canopy to the bottom of the spring [Figure G].
3.0 INSPECTION:
3.1 Verify the grommet is secure.
3.2 Tapes should be straight.
3.3 Tackings should be secure.
4.0 DISASSEMBLY: Mesh repair.
4.1 Remove the tackings used to secure the base of the pilot chute to the spring.
4.2 For small holes, turn the mesh inside out and zigzag the edges together.
5.0 REASSEMBLY:
5.1 Reattach the bottom of the pilot chute to the spring with hand tacking.
6.0 INSPECTION:
6.1 Tapes should be straight.
6.2 Tackings should be secure.

Parachute Repair Procedure
TITLE: 7.4.2 Reserve Free Bag Repair – Grommet Pullout
NUMBER OF PAGES: 2
APPLICABLE PRODUCTS: Most reserve free bags.
DESCRIPTION: General repair to the reserve free bag.
AUTHORIZED REPAIRMEN: FAA Master Parachute Rigger
MATERIALS: E thread
1 1/2" Ty-3 tape
Grommets to match the original type and size
MACHINES: 301 Straight Stitch—Medium Duty 7-11 SPI
EQUIPMENT:
Scissors
Seam ripper or scalpel
Marking pencil
6" ruler
Hot knife
Grommet set
Hole punch
PROCEDURE
Note: Most reserve free bag designs are fairly robust. The most common types of damage seen are
the pulling out of the grommets in the tongue of the bag [Figure A] and tearing out of fabric from the
binding tape due to overstressing during packing. Damage to the bridle portion of the free bag is
generally not repairable nor allowed by most manufacturers. Consequently, any damage in this area
would necessitate the replacement of the bag. The following procedure deals with the repair of the
tongue area and replacement of the grommets.
1.0 DISASSEMBLY:
1.1 Remove the grommets from the tongue [Figure B].
1.2 Remove the binding from the tongue area by unpicking the
stitching [Figure C].
2.0 REASSEMBLY:
2.1 Cut two pieces of 1 1/2" Ty-3 tape and overlay them on each
side of the damaged area. Sew around the edges of the tape
and down the center to secure it [Figure D].
7-84
2.2 Trim the ends of the tape to match the shape of the tongue.
2.3 Using the single needle machine, reapply the binding tape around the edge of the tongue
[Figure E].
2.4 Punch new holes over the exact position as the original ones [Figure F].
2.5 Insert new grommets [Figure G].
3.0 INSPECTION:
3.1 Reinforcing tape must be secure.
3.2 Binding must be resewn.
3.3 Grommets must be set and secure.

Parachute Repair Procedure
TITLE: 7.4.3 Main Pilot Chute Repair – Top Canopy Reinforcing
NUMBER OF PAGES: 1
APPLICABLE PRODUCTS: Most main hand deploy pilot chutes.
DESCRIPTION: Repair of the apex area of a hand deploy pilot chute.
AUTHORIZED REPAIRMEN: FAA Senior or Master Parachute Rigger
MATERIALS: E thread
3/4" Ty-3 tape
MACHINES: 301 Straight Stitch—Medium Duty 7-11 SPI
EQUIPMENT:
Scissors
Seam ripper or scalpel
Marking pencil
6" ruler
Hot knife
PROCEDURE
Note: Most repairs of the main pilot chute consist of fabric or mesh repairs and may be repaired similar
to canopy procedures. The most common damage seen on main pilot chutes is in the area of the
apex and the hand deploy handle [Figure A]. This area is subject to fairly severe stress and strain.
The following procedure deals with the apex area repair. It should be noted that if the repair is too
