+ Nylon Parachutes Get a Monthly Airing in a Dry Locker Once every 30 days, whether it has been used or not, every Navy parachute is unpacked and hung full length in a special chamber with a temperature of about 70° F. and humidity of 54 percent. All naval air sta tions and aircraft carriers have equipment for this pur pose. After hanging 24 hours, chutes are ready for inspec tion and repacking. Here a Wave student rigger lowers a parachute slowly while her classmate carefully coils the nylon suspension lines to prevent snarling. -> Pat and Classmates Watch the Instructor as He Checks a Chute After leaving the dry locker, the parachute is stretched taut on a smooth topped table, where each line and segment is checked for chafing, tears, and other signs of wear. Folding comes next, start ing with the canopy. Here an instructor (holding line) demonstrates the operation to the class; normally two riggers make a packing team. The rigging kit (fore ground) contains packing tools-an awl, a bag of shot used as a weight, and as sorted hooks, bars, and pins which help in fitting the 790 square-foot canopy neatly into its container.
