2. Pack Releasing Cone (T-10R). In the front view of the pack-releasing cone (looking straight at the
drilled hole opening), the hole position must clearly extend beyond the teardrop surface and break
the edge of the cone surface. In addition, when routing the cone 90 degrees (making sure the
suspected edge faces towards the individual), a broken edge, or concave dip in the cone surface
must also be clearly visible. If an unserviceable cone is identified, that pack tray assembly must be
removed from service and the pack release cone must be replace before the pack tray can be placed
back into service. Check the position of the drilled hole on both sides of the cone to determine if the
edge of the drilled hole has broken into the edge of the cone beyond the flat teardrop surface. The
teardrop surface is defined as the flat surface on each side of the cone from the top of the cone to
the base. The point of the teardrop faces towards the base of the cone. If the parachute is packed,
apply a downward pressure on the pack fastener and grommet to expose as much of the tip of the
pack-releasing cone as possible. While checking for the position of the drilled hole, move the ripcord
locking pins from side to side, with out removing them from the cone, to obtain the best view of the
drilled hole location. Pay particular attention to the outside edge of the drilled hole to see if it breaks
the edge of pack releasing cones since that would be the area in which the pack fastener would most
likely catch or hang up. The drilled hole does not have to be completely centered within the teardrop
surface. If it is questionable whether or not the drilled hole is beyond the teardrop surface or has
broke the edge of the cone, rotate the cone 90 degrees in both directions to see if there is a broken
edge or concave dip in the cone’s surface. If it has not broken the edge of the cone to cause a
concave dip, it is still considered a serviceable cone.
3. Cloth. Inspect for breaks, burns, cuts, frays, holes, rips, snags, tears; loose, missing or broken
stitching or tacking; weak spots, wear, or deterioration.
4. Fabric tape, webbing, and cordage. Inspect for breaks, burns, cuts, frays, holes, snags, tears,
incorrect weaving, and sharp edges formed from searing; loose, missing, or broken stitching, tacking,
whipping, and weaving; weak spots, wear, and deterioration.
5. Pressure-sensitive (adhesive) tape. Inspect for burns, holes, cuts, tears, weak, spots, looseness and
deterioration.
6. Rubber and elastic. Inspect for burns, cuts, holes, tears, weak spots; loss of elasticity and
deterioration.
IN-STORAGE INSPECTION
An in-storage inspection is a physical check conducted on a random sample of air delivery equipment,
which is located in storage. The purpose of the inspection is to insure that the equipment is ready for
issue, that the item is properly identified and segregated from other types of equipment, that no damage
or deterioration of equipment has been incurred, and that all modifications or similar action requirements
have been completed. The inspection shall also concern the methods and procedures applied to the
storage of air delivery items, the adequacy of storage facilities, efforts of pest and rodent control, and
protection against unfavorable climatic conditions. Air delivery equipment, which is in storage, will be
inspected at least semiannually and at more frequent intervals if prescribed by the local parachute
maintenance officer. The frequency of inspection may vary according to the type of storage facilities and
local climatic conditions. In-storage inspection will be conducted only by parachute rigger personnel
designated by local parachute maintenance officer.
EQUIPMENT DISPOSITION
Air delivery equipment may be rendered unserviceable by either normal fair wear or by aging and will
subsequently be repaired, modified, or condemned, as appropriate. Equipment that is uneconomically
reparable (outdated) will be condemned. Disposition of air delivery equipment that is condemned,
unserviceable, or for which the serviceability is questionable, will be accomplished using the following
procedures, as applicable.
