Electromagnetic Interference (5.5.5.5) - ANswEr-caused when electromagnetic fields
(radio waves) induce high-frequency voltages in a wire or component. (AC 43.13-1B 11-
89)
Grounding (5.5.5.5) - ANswEr-Establishing a physical wire path that gives electricity a
path to earth/ground.
Bonding (5.5.5.5) - ANswEr-Connection of non-current carrying conductive elements ie.
enclosures and structures.
Conductor plating (5.5.5.1) - ANswEr-Copper wire plated with Tin, Silver, or Nickel. Tin is
the most common. wire plating has a slower oxidation rate than bare copper.
Voltage drop in wires (5.5.5.1) - ANswEr-Should not exceed 2% of the regulated voltage
when the generator is carrying rated current or the battery is being discharged at 5
minute rate.
The allowable voltage drop in a 28 volt continuous circuit is:
a. 1 volt
b. 2 volts
c. 5 volts
d. 4 volts - ANswEr-a. 1 volt
Voltage rating (5.5.5.1) - ANswEr-The voltage rating of a cable is the highest voltage that
may be continuously applied to a completed cable construction in compliance with the
relevant cable standard or specification
, Shielded wire (5.5.5.1) - ANswEr-Electrical wire that is enclosed in a braided metal jacket.
Electromagnetic energy radiated from the wire is trapped by the braid and is carried to
ground.
Receiving Inspection (5.4.1.1) - ANswEr-ensure that incoming parts are checked against
purchase orders, manufacturers specifications, drawings and dimensions and other
available documentation to CONFIRM AUTHENTICITY of the material. Conformance to
applicable technical standards will be verified. Incoming material must be separated from
previously inspected material
cable (5.5.5.1) - ANswEr-A bundle of wires covered by rubber or plastic along which an
electric current can pass.
New Equipment Acceptance (5.4.1) - ANswEr-Receiving inspection, physical condition,
inventory of equipment and accessories for installation
Visual inspections (5.4.1.2) - ANswEr-New parts will be visually inspected to confirm the
PN and SN, the part markings, and general condition. All parts/components must be
accompanied by documents the CLEARY INDICATE APPROVED/ACCEPTABLE SOURCE.
Suspected Unapproved Parts (SUP) - ANswEr-Red Tagged - Placed in quarantine - report
using FAA Form 8120-11. Ref. AC 21-29.
Direct Marking (5.5.5.3) 1 - ANswEr-Several different methods can be used to mark
directly on the wire: hot stamp marking, ink jet printers, and laser jet printers. The hot
stamp method can damage the insulation of a newer type of wire that utilizes thin
insulators.
Indirect Marking (5.5.5.3) 2 - ANswEr-Identification sleeves can be used if direct marking
on the wire is not possible. Indirectly-marked wire or cable should be identified with
printed sleeves at each end and at intervals not longer than 6 feet. The individual wires
inside a cable should be identified within 3 inches of their termination
Wire Identification (5.5.5.3) - ANswEr-All wire used on aircraft must have its type
identification imprinted along its length. It is common practice to follow this part number
with the five digit/letter Commercial and Government Entity (CAGE) code identifying the
