Parachute Repair Procedure
TITLE: 7.5.3 Automatic Activation Device (AAD) Installation
NUMBER OF PAGES: 3
APPLICABLE PRODUCTS: Most 1-pin sport piggyback systems.
DESCRIPTION: Installation of a CYPRES® AAD to a 1-pin sport piggyback harness and
container system.
AUTHORIZED REPAIRMEN: FAA Master Parachute Rigger
MATERIALS: E thread—color to match
CYPRES® installation kit
Spandex® fabric [Optional]
MACHINES: 301 Straight Stitch—Medium Duty 7-11 SPI
308 Zigzag—Medium Duty 7-11 SPI
EQUIPMENT:
Scissors
Seam ripper or scalpel
Marking pencil
12" ruler
Hot knife
Wallpaper roller
PROCEDURE
Note: The following procedure is representative of a typical installation of the CYPRES® AAD into
a modern 1-pin reserve container system. While providing guidance for this operation, it is imperative
that the rigger possesses the proper instructions from both the harness-container manufacturer
and the AAD manufacturer.
1.0 DISASSEMBLY:
1.1 Open the right side corner of the reserve container
[Figure A]. While this might not be needed on some size
containers, it generally makes the installation of the
pocket easier and it’s not that hard to close the corner
back up.
2.0 REASSEMBLY:
2.1 Mark the center of the container wall at the bottom [Figure B].
2.2 Mark the center of the Spandex® portion of the CYPRES® pocket [Figure C]. Do not mark
the center of the entire pocket. The Spandex® must be centered on the wall to allow for the
correct positioning of the CYPRES® processing unit.
2.3 Align the marks and the pocket as close to the bottom of the wall as possible [Figure D].
7-99
2.4 Sew around the pocket with the single needle machine.
Backstitch .5" at each of the corners for reinforcing.
2.5 Next, install or create a cable channel for the control cable.
Some systems such as the one shown, can be modified to
provide the channel. Others need to use the adhesive backed
channel provided with the CYPRES® kit.
2.6 BUILT-IN CHANNEL MODIFICATION CONFIGURATION.
2.6.1 Mark the bottom and top of the pack tray cover as shown
[Figure E]. Place a hand tack at the A position. Unpick the
stitching between the corner bar tack and the hand tack at
the A position. Also, unpick the stitching between the B bar
tacks.
2.6.2 There is now a built-in channel to slide the control cable thru
and stow the excess cable as well [Figure F].
2.7 ADHESIVE CHANNEL INSTALLATION.
2.7.1 Measure the distance along the long axis of the reserve container
from the bottom of the pocket location to the top of
the container near the planned location for the control unit
[Figure G].
2.7.2 Cut a piece of the adhesive backed channel to the same
length. Remove the adhesive covering and position the channel
in place. Roll the channel with the wallpaper roller to
secure the adhesive.
2.8 Locate the position for the control pocket. Unpick the stitching
that holds the main container to the backpad [Figure H].
2.9 Insert the pocket with the mouth towards the channel opening
and restitch the container to the backpad [Figure J].
Make sure the control head will fit into the pocket.
