TM 10-1670-272-23&P                                                         0009 00       0009 00-4 Air delivery equipment that 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.  Only parachute rigger personnel designated by the local parachute maintenance officer will conduct in-storage inspections. 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  Equipment that is uneconomically reparable (outdated) will be condemned.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 questioned, will be accomplished using the following procedures, as applicable: 1.  Item requiring repair or modification.  An air delivery item that requires repair or modification will be tagged in accordance with DA PAM 738-751.  Subsequent work on the item will be performed at the maintenance level specified for the maintenance function in the applicable supporting technical publication. 2.  Parachutes with exhausted age or service life.  Any parachute component or air delivery equipment whose age or service life has expired as specified in TB 43-0002-43 will be removed from service, condemned, and tagged as prescribed by DA PAM 738-751. 3.  Disposition of condemned air delivery equipment.  Condemned equipment, other than fatality parachutes, will be removed from service and disposed of in accordance with current directives listed in this work package.   4.  Rejected equipment.  Equipment which, prior to use, is deemed unserviceable for use will be reported in an EIR in accordance with DA PAM 738-750, as authorized by AR 750-1.  Each applicable item that is defective will be held and safeguarded pending receipt of disposition instructions from the National Maintenance Point (NMP).  In all instances, EIR exhibit material will be handled as prescribed in DA PAM 738-750.  If the quality or the serviceability of an item is questionable, clarification and assistance may be obtained by contacting Commander, US Army Soldier and Biological Chemical Command, ATTN: AMSSB-RIM-E(N), Kansas Street, Natick, MA 01760-5052. 5.  Equipment of doubtful serviceability.  Equipment that has had previous use and has not exceeded normal fair wear or aging criteria, but of which further serviceability is doubtful, will be tagged as prescribed in DA PAM 750-751.  In addition, the equipment will be reported in an EIR, in accordance with DA PAM 738-750 and AR 750-1.  The item(s) in question will be held as EIR exhibit material as outlined in DA PAM 738-750 pending receipt of disposition instructions from the NMP.  A maintenance activity holding EIR exhibit material will not tamper with the applicable item(s) or make any attempt to ascertain cause factors. Unnecessary handling of EIR exhibit material may disturb or alter peculiar aspects of the affected item(s) that might affect the judgment of engineering personnel who have the responsibility for final evaluation of EIR actions. 6.  Equipment immersed in salt-water.  Any air delivery item equipment constructed from cotton material that has been immersed in salt-water will be condemned.  Cotton thread used for tacking and sewing on nylon parachute packs that have been immersed in salt-water will only be replaced when there is visible evidence or deterioration such as extreme discoloration or indications of broken thread. Any air delivery equipment constructed of nylon or rayon material that has been immersed in salt-water for a period less than 24-hours, but which cannot be rinsed within 48-hours after recovery will also be condemned.  However, if the cited time limitations can be met, then immediately upon recovery, suspend or elevate the recovered equipment in a shaded area and allow the item(s) to drain for at least 5-minutes.  Do not attempt to wring the equipment fabric or the suspension lines.  Within 48-hours after recovery, under the supervision of a qualified parachute rigger (92R), rinse the recovered equipment as indicated in WP 0008 00.   END OF WORK PACKAGE
