2" past the end of
the side flap. Remove
the side flap.
2.0 REASSEMBLY:
2.1 Take the new flap and sew it in place on the main container starting approximately .38" from
the corner [Figure C]. On this design and others like it, the lower end of the main riser cover
is unstitched during removal of the main flap. When sewing the new flap in place, make sure
that the side flap is sewn to the main container first and then the riser cover on top of it. Look
at the opposite side to see which is on top and duplicate.
2.2 If option 1 was used, take the original binding tape, fold over the seam and sew in place with
two rows of stitching. Note that there is a second row of stitching sewn directly on top of the
inside row of stitching for reinforcement [Figure D]. This is very important.
2.3 If option 2 was used, it will be necessary to replace the binding tape with new. Stitch down
the loose end of the binding tape at the top and then overlap the tape by approximately 2"
using the double needle machine and tape binder [Figure E]. Overstitch the inside row for
reinforcement.
2.4 Trim the bottom end of the binding tape at the corner.
2.5 Note that the junction of the side flap and riser cover is overstitched and reinforced as needed
[Figure F].
2.6 Close the bottom of the container as per the original and reinforce as required.
3.0 INSPECTION:
3.1 Check that the flap is installed correct side out.
3.2 Check the inside binding for reinforcing stitching.
3.3 The side flap/riser cover should be stitched and reinforced.
3.4 The container bottom must be closed correctly and reinforced.

TITLE: 7.2.6 Bottom of Container (BOC) Pocket Replacement
NUMBER OF PAGES: 1
APPLICABLE PRODUCTS: Any main container with a BOC pocket configuration.
DESCRIPTION: Installation of a BOC pocket to the main container.
AUTHORIZED REPAIRMEN: FAA Senior or Master Parachute Rigger
MATERIALS: E thread—color to match
MACHINES: 301 Straight Stitch—Medium Duty 7-9 SPI
308 Zigzag—Medium Duty 7-11 SPI
EQUIPMENT:
Scissors
Seam ripper or scalpel
Marking pencil

PROCEDURE
Note: The following technique is typical of many modern container systems. This procedure
addresses only the disassembly of the container and replacement of a factory made replacement part.
It does not address the manufacture of a replacement part. Depending on the size of the container
assembly, it may be possible to do the replacement of the BOC pocket with the reserve packed.
However, the smaller the system, the more difficult it will be. If
the container cannot be placed under the machine, then remove
the reserve canopy.
1.0 DISASSEMBLY:
1.1 Mark the location of the corners of the BOC pocket on
the container with a marking pencil.
1.2 Open the lower right corner of the main container
[Figure A].
1.3 Remove the old BOC pocket.
2.0 REASSEMBLY:
2.1 Locate the new BOC pocket on the container at
the marks of the old pocket and pin in place
with T-pins [Figure B].
2.2 Stitch around the perimeter of the pocket with
the single needle machine. Backstitch at the
corners for reinforcing [Figure C].
2.3 Restitch the corner of the main container as per
the original configuration.
3.0 INSPECTION:
3.1 Check the orientation of the pocket with the
opening to the right (unless for left-handed
deployment).
3.2 Check the stitching and corner reinforcing.
