Inspection Automatic Activation Device (AAD) Installation Procedure Disassembly Reassembly 3.  Align the marks and the pocket as close to the bottom  of the wall as possible.  [Figure D] 1.  Mark the center of the container wall at the bottom.  [Figure B] •  Verify the length is correct. •  Check that the bar tacks are at the original location. •  Applicable products: Most 1-pin sport piggyback  systems •  Description: Installation of a CYPRES $^{®}$ AAD to a  1-pin sport piggyback harness and container system 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. •  Authorized repairmen: FAA Master Parachute Rigger  •  Materials: E thread—color to match, CYPRES $^{®}$  installation kit, and Spandex$^{®}$ fabric (optional) •  Machines: 301 straight stitch—medium duty 7–11 SPI  and 308 zigzag—medium duty 7–11 SPI •  Equipment: Scissors, seam ripper or scalpel, marking  pencil, 12-inch ruler, hot knife, and wallpaper roller 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. 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 is not that hard to close the corner back up. 7-77
