TM 1-1520-240-BD (c) Procedures.      The   following   procedures are typical when performing emergency wire repairs: • Before  leaving  for  the  downed  aircraft  site,  obtain copies  of  the  "flight  essential"  serviceability  tables (as    a    minimum)    for    the    aircraft    model    to    be recovered. • At  the  site,  perform  an  assessment  of  wire  to  be repaired  prior  to  self-recovery  flight  of  the  aircraft. Use  the  serviceability  tables  to  determine  wires  to be repaired. • Select the necessary tools and materials and make necessary emergency wire repairs. • Use the teflon tape to "cap" off severed nonessential wiring.    The  scissors  of  the  Swiss  Army  knife  may be used to cut the teflon tape.  Non-essential wiring repair   is   deferred   until   return   to   an   AVIM/AVUM area. • Use  the  DMM  to  verify  proper  continuity  (aircraft non-powered) and voltage levels (aircraft powered). • Return the DMM, tools, and unused repair materials to  the  proper  storage  compartment.    Verify  the  kits inventory and prevent FOD. • Perform    aircraft    ground    check    and    fly    to    an AVIM/AVUM  area.    This  is  a  one-time  flight  of  one hour maximum. • At    the    AVIMIAVUM    area,    convert    "emergency" repairs  to  "temporary"  or  "permanent"  status  using the HT-900 heat gun (paragraph 9-7b(3)). • Perform ACM/BDR assessment of aircraft and make additional necessary repairs per paragraphs 9-7b(1), 9-7b(2), and 9-7b(3). 9-8. ACM/BDR ELECTRICAL WIRING SYSTEM REPAIR   DEFINITIONS   AND   CAPABILITIES .      The ACM/BDR  wiring  repair  set  provides  for  three  types  of aircraft electrical wiring repairs, classified as "PERMANENT," TEMPORARY" and "EMERGENCY" as defined in paragraphs 9-8a.  through 9-8c.  Examples of typical    ACM/BDR    repairs    and    techniques    will    be provided in paragraph 9-9. a. Permanent  Repair.    A  permanent  repair returns  the  electrical  wiring  system  to  full  capability,  as manufactured,    with    no    degradation    of    any    system operating   characteristics.      No   periodic   inspection   or replacement is required with a permanent repair. b. Temporary   Repair.   A   temporary   repair returns the electrical wiring system to a reduced level of capacity,   with   a   possible   slight   reduction   of   system operational   capability.      Temporary   repairs   must   be reinspected    at    140    flight    hours.        At    this    time,    a permanent  repair  will  be  performed  or  an  extension  of use for the temporary repair will be granted. c. Emergency Repair.  An emergency repair is performed to enable the recovery of a downed aircraft to an AVIM/AVUM area Emergency repairs are allowed for  a  one-time  flight  not  to  exceed  one  hour  duration. Most   emergency   repairs   can   be   easily   upgraded   to permanent or temporary status at the AVIM/AVUM area. NOTE Temporary   and   emergency   repairs established  in  this  TM  will  only  be applied in time of war. The commander or his designated representatives may authorize deviations  necessary  to  accomplish wartime requirements. 9-9. REPAIR  TECHNIQUE.    Electrical  wiring  system ACM/BDR is used to restore damaged circuits which are essential   to   the   mission   and   to   make   nonessential circuits  safe,  in  the  shortest  possible  time.    The  best techniques and materials available are used to make the most suitable repair within the allotted repair time.  The methods described are the most preferred, but are by no means  exhaustive.    In  battle,  situations  may  arise  that will require the ACMIBDR assessor and repair personnel to   develop   innovative   repair   techniques   beyond   the scope    of    this    TM.        This    paragraph    describes    and illustrates  repair  capabilities  to  broken  and/or  damaged wires, shielded and co-axial cables, electrical connectors and associated electrical components in the combat  environment.    Example  of  repairs  meeting  the ACM/BDR permanent, temporary, and emergency repair standards are shown. a. Permanent    Repair    Techniques.        This paragraph describes permanent repair techniques for: • Unshielded and shielded primary wires. • Cable shielding and cable shield termination. 9-8
