TM 1-1520-240-BD b. Temporary    Repair    Techniques.        Repair performed  under  the  guidelines  of  this  paragraph  may be used for a period of 140 flight hours.  At this time of the  temporary  repair  is  to  be  inspected  and  a  decision made to either extend the use of the temporary repair or make  a  permanent  repair.    This  paragraph  describes temporary repair techniques for co-axial cable and large wire-side splices, connection or junction boxes, terminal board bridging, and insulation repair with heat- shrinkable  tape.    Prior  to  performing  any  of  the  listed repairs, the repair technician must be knowledgeable in the basic repair procedures and proficient in the use of the wiring repair tools and materials. (1) Co-Axial Cable Splice.    The  wire  repair kit     contains     materials     for     making     environmentally protected  splices  on  aircraft  co-axial  cables.    As  these splices  are  a  new  item,  and  not  fully  qualified  at  this time,  splices  performed  with  these  materials  must  be categorized   as   temporary,   even   though   performance loss  of  a  co-axial  cable  system  using  these  splices  in minimal.  Figures 9-27 through 9-32 illustrate the basic procedure  to  splice  co-axial  cables  of  the  types  noted. These  instructions  are  the  same  as  the  repair  material storage    container.        One    co-axial    cable    splice    is allowable  for  every  eight  feet  of  co-axial  cable  length. Additional  splices  per  cable  may  be  authorized  by  the maintenance authority as local conditions warrant. NOTE The item number on each illustration  indicates  the  location of    the    repair    material    storage container    and/or    required    tools within the wiring repair kit portion of the repair set. After completing a  co-axial splice, obtain  a  chart  record  of  the  co- axial cable signature for inclusion in the aircraft records.  This chart record is to be obtained using the TDR.    Annotate  the  chart  record with  aircraft  serial  number,  date, cable number, vertical and horizontal    TDR    attentions,    and any  other  data  of  interest.    This chart record is to be used to verify the    integrity    of    the    repair    and provide     a     baseline     for     future comparison in the event of system degradation.
