Emergency Repair Techniques. Emergency
repairs allows a downed aircraft to make a one-time
flight of up to one hour duration to an AVIM or AVUM
area. This paragraph describes emergency repair
techniques for unshielded, primary wires, damaged
insulation, and wire bundle forming. These repair are by
no means exhaustive. Innovative repairs may be
developed 'on-site" to recover the downed aircraft. Prior
to performing any of the listed repairs, the maintenance
technician must be knowledgeable in use of the repair
tools and materials.
NOTE
Temporary and emergency repairs
established in this manual will only
be applied in time of war. The
commander
or
his
designated
representatives
may
authorize
deviations necessary to accomplish
wartime requirements. Permanent
repairs may be used at any time.
(1)
Unshielded
Primary
Wire
Splice.
Unshielded primary wire splice repairs are performed
with the splices of wire repair segments contained within
the repair kit. The procedures are identical as those
described in paragraph 9-9a(1), except the place sealing
sleeve, heatshrink operation is deferred until the return
of the aircraft to the AVIM or AVUM area. In lieu of the
heat-shrink operation, the splice-seal sleeve is held in
place with a short piece of Teflon tape. The Teflon tape
is applied to the small end of the sealing sleeve after
centering the sleeve over the crimp barrel as shown in
Figure 9-36.
NOTE
The repair may be upgraded from
emergency to permanent status upon
return of the aircraft to a AVIM/AVUM
area, removing the Teflon tape, and
performing the heat-shrink operation
per paragraph 9-9a(1).
(2)
Insulation Repair. Emergency repair to
damaged wire insulation may be accomplished by
wrapping the damaged insulation with four layers of
Teflon tape. Extend the tape wrap one inch from each
end of the damaged area over undamaged insulation. If
over 25% of the wire conductors are severed, and time
permits, an emergency splice should be performed.
(3)
Wire-Bundle Forming. Often, wire bundle
tie tape and/or self-clinching cable straps will either be
found to be damaged or will require removal prior to
performing emergency repairs. The repair kit contains
replacement self-clinching cable straps.
