PROCEDURE
1.0 LAYOUT:
1.1 Draw the shape of the BOC pocket on the para-pak fabric to the size required to fit the pilot
chute. This will be the base panel.
1.2 Fold the Spandex® fabric in half and cut to the same size as the base panel. This will be the
pocket panel. Make sure the grain of the fabric is parallel with the length of the pocket for
stretch. Trim 1/2" off the end opposite the fold [Figure A].
2.0 ASSEMBLY:
2.1 Open the sides of the pocket at the folded end and insert the length of elastic tape. Sew the
tape in place with the single needle on both sides.
2.2 Mark the center of the mouth and bar tack the elastic reinforcing as shown [Figure B].

2.3 Lay the pocket on the para-pak base and sew in place [Figure C]. (Hint—Sewing with the
Spandex® on the bottom and the para-pak on top will minimize stretch from the presser foot.)
2.4 Bind the pocket, starting at the bottom corner opposite the mouth of the pocket [Figure D].
2.5 Bar tack the mouth of the pocket securing the elastic reinforcing on both sides [Figure E].
2.6 The pocket is now complete and ready for installation.

TITLE: 7.7.1 Hand Tacking Techniques
NUMBER OF PAGES: 2
APPLICABLE PRODUCTS: Any systems requiring hand tacking.
DESCRIPTION: Securing housings, hardware, etc., with hand tackings.
AUTHORIZED REPAIRMEN: FAA Senior or Master Parachute Rigger
MATERIALS: Nylon supertack tacking thread
MACHINES: None
EQUIPMENT:
Scissors
Assorted hand tacking needles
Modified navy end tab
PROCEDURE
Note: Hand tacking is an integral part of rigging skills. There are numerous places where components
or parts are joined. Hardware, housings, cones, and other parts require hand tacking to secure
them to their positions. The following examples show typical tacking techniques.
1.0 PILOT CHUTE:
1.1 Take the needle and supertack and pass it through the
reinforcing tape at the bottom of the pilot chute mesh
capturing the spring coil [Figure A].
1.2 Cross over the radial seam reinforcing tape and again
pass the needle through the reinforcing tape and capturing
the spring coil as before [Figure B].
1.3 Secure the ends of the supertack with a surgeon’s knot
and locking knot [Figure C]. Trim to a 3/4" tail.
