Exam 2025 Questions and Answers
Electromagnetic Interference (5.5.5.5) - ✔✔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) - ✔✔Establishing a physical wire path that gives electricity a path to
earth/ground.
Bonding (5.5.5.5) - ✔✔Connection of non-current carrying conductive elements ie.
enclosures and structures.
Conductor plating (5.5.5.1) - ✔✔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) - ✔✔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 - ✔✔a. 1 volt

, Voltage rating (5.5.5.1) - ✔✔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) - ✔✔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) - ✔✔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) - ✔✔A bundle of wires covered by rubber or plastic along which an
electric current can pass.
New Equipment Acceptance (5.4.1) - ✔✔Receiving inspection, physical condition,
inventory of equipment and accessories for installation
Visual inspections (5.4.1.2) - ✔✔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) - ✔✔Red Tagged - Placed in quarantine - report
using FAA Form 8120-11. Ref. AC 21-29.
Direct Marking (5.5.5.3) 1 - ✔✔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.
