1. 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)
2. Grounding (5.5.5.5)
Establishing a physical wire path that gives electricity a path to
earth/ground.
3. Bonding (5.5.5.5)
Connection of non-current carrying conductive elements (e.g., enclosures
and structures).
4. 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.
5. 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 a 5-minute rate.
6. The allowable voltage drop in a 28-volt continuous circuit is:
a. 1 volt ✅
7. 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.
,8. 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.
9. Receiving Inspection (5.4.1.1)
Ensure incoming parts are checked against purchase orders, manufacturers'
specifications, and other documentation to confirm authenticity.
10. Cable
A bundle of wires covered by rubber or plastic along which an electric
current can pass.
11. New Equipment Acceptance (5.4.1)
Includes receiving inspection, checking physical condition, and inventory of
equipment and accessories for installation.
12. Visual Inspections (5.4.2.1)
A general visual inspection of incoming material including physical
condition, proper identification, and quantities.
13. Suspected Unapproved Parts (SUP)
Parts that do not conform to approved data or are not properly
documented. Must be quarantined, investigated, and reported if
determined to be unapproved.
14. Direct Marking (5.5.5.3)
Several 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 newer wire types with thin insulators.
15. Indirect Marking (5.5.5.3)
Identification sleeves can be used if direct marking is not possible.
,Indirectly-marked wire should be identified at each end and at intervals not
longer than 6 feet.
16. Wire Identification (5.5.5.3)
All wire used on aircraft must have its type identification imprinted along its
length. This often includes a Commercial and Government Entity (CAGE)
code identifying the manufacturer.
17. Wire Identification Requirements (5.5.5.3)
Identification markings should be placed at each end of the wire and at 15-
inch maximum intervals. Wires less than 3 inches in length need not be
identified.
18. Performance Standards - Technical Standard Order (TSO) (5.3.6.3)
A minimum performance standard for specified materials, parts, and
appliances. TSO authorization is NOT an approval to install in an aircraft,
only authorization to manufacture the part or material.
19. Performance Standards - Parts Manufacturer Approval (PMA)
(5.3.6.3)
PMA production approval allows you to produce and sell FAA-approved
aircraft articles that are eligible for installation on FAA Type Certificated
Products.
20. Schematic diagram (5.3.8.2)
Used to illustrate a principle of operation and indicate component
locations. Best utilized for troubleshooting.
21. Preservation and Storage of Aviation Parts (5.4.1)
Articles stored for installation shall be stored or preserved in accordance
with manufacturer's recommendations to provide maximum protection
from damage or deterioration.
, 22. Preliminary Inspection (5.4.2.1)
Visually inspect all items for physical damage and ensure all necessary and
current information and specifications are available.
23. Record Keeping
Includes: Work Order Form, Amended Equipment List, Service Bulletins/AD
compliance sheets, copies of technical data, function test/calibration results,
configuration data, component traveler, and copies of Return to Service
documents.
24. Return to Service of an article after maintenance/alteration will
include:
A log book entry, FAA Form 337 for major repair or alteration, and an
Amended Equipment List.
25. Calibrated equipment
Check that test equipment has a current calibration label attached.
26. Hardware Identification
AN = Air Force Navy Standard, NAS = National Aircraft Standard.
27. What prevents RFI?
Grounding and bonding.
28. Bonding Jumper length
Jumpers should be kept as short as practicable, and the resistance of each
connection should not exceed 0.003 ohm.
29. Bonding and grounding surface prep
Nonconducting finishes, such as paint and anodizing films, should be
removed to ensure a low-resistance connection.
