ARMY TM 10-1670-281-23&P AIR FORCE T.O. 13C5-32-2 NAVY NAVAIR 13-1-32 2-16.  Packing the 64-Foot Cargo Parachute, Model G-12D (cont). (1)  Top, that portion of the equipment that is farthest from the packing surface. (2)  Bottom, that portion of the equipment that is nearest to the packing surface. NOTE Packing of the G-12D parachute will require a 3-person team. c.   Preparing Parachute for Proper Layout.    Prepare  the  parachute  for  proper  layout  by  positioning  the canopy in an elongated manner on a suitable packing surface, with the vent lines located next to a stationary post  (figure  2-9)  and  the  suspension  risers  near  a  tension  device.    Disconnect  the  pilot  parachute,  static  line and deployment line.  To complete the proper layout, perform the following: (1)  Removing canopy inversion.  Inspect the canopy vent lines to determine if the canopy is inverted.  If the  vent  lines  are  located  on  the  inside  of  the  upper  lateral  band,  the  canopy  is  inverted.    To  remove  the inversion, lift the canopy skirt and walk up through the canopy to the vent area.  Grasp the bridle loop and pull the canopy vent down through the canopy skirt between two adjacent suspension lines (figure 2-10).  On the outside of the canopy, pull the canopy vent back to the stationary post.  Attach the bridle loop to the stationary post. (2)  Locating suspension lines in proper layout.  Locate the top center gore of the canopy and divide the suspension lines into two groups, Lines 1 through 32 in the left group and lines 33 through 64 in the right group. Maintain the line group separation and remove any turns, tangles or twists from the suspension lines as follows: (a)  Turns.  A turn occurs when one group of suspension lines rotates around the opposite group of suspension lines.  Remove the turn by rotating the suspension lines (figure 2-11) in a direction opposite to that of the turn. (b)    Tangles.    To  remove  a  tangle,  or  tangles,  in  the  suspension  lines,  begin  by  maintaining suspension line group separation and work the tangle(s) to a point as close as possible to the connector links. Select the top line(s) forming the tangle and, using the left hand, lift the line(s) away from the lines in the group. Using  the  right  hand,  reach  through  the  opening  formed  by  the  raised  lines  and  pull  the  suspension  risers through the opening (figure 2-12).  Repeat the procedure to remove each remaining tangle in either group of suspension lines. (c)  Twists.  A twist occurs when the suspension lines in one group become improperly crossed. To determine if twists are present, trace lines 1 and 64 from the canopy skirt to the connector link assemblies. If the lines cannot be traced directly to the inside of the top connector links, the suspension lines are twisted. Remove a twist by rotating the suspension risers between the suspension line groups in a direction opposite to that of the twist (figure 2-13). (d)  Canopy layout.  Check the canopy assembly for proper layout by tracing suspension lines 1 and 64 from the canopy skirt to the inside of the top connector-links and lines 32 and 33 from the canopy skirt to the inside of the bottom connector links.  To complete the proper layout of the canopy, arrange the risers, connector link assemblies and suspension clevis as indicated in figure 2-14. 2-26
