TM 10-1670-293-23&P            0009 00 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 deliver equipment.  Condemned equipment, other than fatality parachutes, will be removed from service and disposed of in accordance with current directives listed in WP 0009 00 of this manual. 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, U.S 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 D 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 immerse in salt-water.  Any air delivery item 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, unless the following actions are performed.  Upon removal from the salt water, the parachute is placed in a single heavy duty plastic trash bag, the top of the bag secured closed and kept in a wet state until a rinse can be performed following normal rinse procedures.  The bag must be doubled when outside temperatures exceed 85 degrees F.  The bags must be inspected after transport and storage to insure the bag did not get torn and the assembly was allowed to dry.   Parachutes recovered using this method must be rinsed NLT than 7 days after the salt water immersion or 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 Change 1 0009 00-4
