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).

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.

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.
