Personnel should refer to SAE ARP5369,
Guidelines for Wire Identification Marking using
the Hot Stamp Process, for guidance on
minimizing insulation damage. TEFLON insulated
wires that cannot be marked by the hot stamp
process may be laser marked or identified by
imprinting the wire number on heat-shrinkable
sleeves installed within 3 inches of each end of the
wire and at 15 inch intervals along the length of
the wire.
98.5.4.3
Shielded and unshielded twisted pair
conducts may be ink jet marked or identified by
imprinting the wire number on heat-shrinkable
sleeves installed within 3 inches of each end of the
wire and at 15 inch intervals along the length of
the wire.
98.5.4.4
Cable Markers will be used on all
wiring of 8 gauge or larger to identify the wire by
code and cable markers will be installed within 3
inches of each end of the wire and at 15 inch
intervals along the length of the wire or where
practical.
98.5.5 Soldering
98.5.5.1 Tin coated and silver-plated
conductors present no unusual problems when
soldering is required. Common 60/40 resin solder
will produce and acceptable solder joint. With
nickel-plated conductors, use of an active flux will
help to produce an acceptable solder joint.
98.5.5.2
Kester solder 44 of Kester liquid flux
1544, or equivalent are products which aid in
soldering nickel-plated conductors. Care should
be used in soldering to prevent wicking of solder
under the insulation. Excessive wicking can be
determined by visually examining the solder
connection.
98.5.6 Wire Support
Conductor breakage can be virtually eliminated
with care and attention to the area of wire
termination.
For aircraft S/Ns 30687, 30576, 30817, 30931 and
30599 airframe wiring routing shall be done in
accordance with Drawing D212-725-8 located in
Appendix A of Chapter 96-00-00. For all S/Ns
except 30687, 30576, 30817, 30931 and 30599,
airframe wiring routing shall be done in
accordance with Drawing D212-725-8-G2 located
in Appendix A of Chapter 96-00-00. Clamping,
terminating, and/or repair of the harness shall be
done following procedures stated in the Bell
Electrical Standard Practices Manual (BHT-ELEC-
SPM), and/or AC 43.13-1B, Chapter 11, Aircraft
Electrical Systems.
98.5.6.1
Wire must be routed and clamped
such that under vibration or maintenance
conditions, any flexing of the wire will not occur at
the termination of the insulation.
98.5.6.2
Crimp contact connectors should have
either a strain relief or a rubber sealing grommet
on the rear of the connector.
98.5.6.3 When installing crimp terminals,
ensure that the wire is installed far enough in the
terminal after crimping the insulation grip of the
terminal has contacted the wire insulation.
98.5.6.4
The greatest care should be taken
where a solder termination is required on any
device mounted in the airframe. Wire breakage as
solder joints is usually due to poor soldering
techniques that result in excessive wicking of the
solder under the wire insulation. Before making a
solder connection, place a suitable piece of heat
shrinkable sleeving over the solder joint are far as
practical and shrink it to its minimum recovery
diameter.
