TM 1-1520-240-BD • Repair  Materials.  Repair  materials  for shielded or unshielded  wire  and  co-axial  cables  are  provided. Bulk  stock  of  shielded  and  unshielded  wire,  tubular shield braid, heat shrinkable tubing and wire harness tie tape is provided on spools stored in a removable rack.    Other  repair  materials  are  stored  in  plastic boxes   to   reduce   FOD   hazard.      The   boxes   are labeled    at    each    end    with    the    repair    materials location reference number, name, and part number. A   label   on   the   box   cover   contains   abbreviated instructions for using the repair material. Additionally, four boxes are used to store connector pins and sockets. (b) Use.      Before   using   kit   components,   a working   knowledge   of   the   instructions,   and   material application  charts  is  required.    The  software  package duplicates  the  environmentally  protected  software.    It provides    instructions    for    the    use    of    the    tools,    the component  selection  charts,  and  proper  application  of repair materials.  Proficiency in the use and application of  this  material  is  necessary  to  achieve  desired  repair capability. (c) Procedure.      The   following   procedure   is typical when using the kit to repair wire or cable: • Perform necessary steps to make aircraft safe, such as  making  sure  all  electrical  power  is  disconnected and  all  systems  are  deactivated.    Disconnect  the aircraft’s battery. • Review DA  Form 2404 and apply the information to the aircraft’s' serviceability tables. • Establish the sequence for wire repair, starting with the  most  essential  requirement  and  proceeding  to non-essential, as time permits. • Perform   diagnostic   and   troubleshooting   tests   as applicable per paragraph 9-7b(1). • Use illuminated magnifying glass to aid in determining  type  and  gage  of  the  wire  used  in  the system. • Use the repair component selection charts to determine the repair material to be used. • Refer to the general wire repair procedure and material instructions to determine the tools required. • Set up and check out the HT-900A Heat Gun at the repair site. • Refer to the contents chart to located required tools and repair material. • Remove  the  necessary  tools  and  repair  materials from the kits.  Verify that the proper stripper blades are   installed   in   the   stripper   handle.      Change   as necessary. • Prepare the wire or co-axial cable for installation of repair material. • Install repair material per instructions. • Perform  the  remaining  repairs  on  other  wire  or  co- axial cables. • Use the test equipment to verify the repair. NOTE Use the TDR to obtain a chart record of  all  repairs  performed  on  co-axial cables.  This record will be included in  the  aircraft  maintenance  records. It  will  provide  a  signature  of  the  co- axial  cable  characteristics  if  a  future system  degradation  occurs.    Clearly annotate   the   chart   record   with   the aircraft  serial  number,  date,  airframe hours,  cable  number,  system,  repair action   performed,   and   vertical   and horizontal TDR attenuations. • Return all tools and unused repair materials to their proper     storage     compartment.          Verify     the     kit inventory  account  for  all  components,  and  prevent FOD. • After     completing     all     repairs     and     verifying     kit inventory, check out aircraft and systems (powered). (4) Emergency Wire Repair and Aircraft Recovery Kit. (a) Mission  And  Major  Components.    The  kit is  used  for  emergency  repairs  on  a  downed  aircraft’s' electrical   wiring   to   allow   a   self-recovery   flight   to   an AVIM  or  AVUM  area.    The  kit  contains  the  basic  tools, repair 9-6
