bonding. Bonding connections are made of screws,
nuts, washers, clamps, and bonding jumpers. Figure
2-55 shows a typical bonding link installation.
Bonding also provides the necessary
low-resistance return path for single-wire electrical
systems. This low-resistance path provides a means
of bringing the entire aircraft to the earth’s potential
when it is grounded.
Whenever you perform an inspection, both
bonding connections and safetying devices must be
inspected with great care.
STATIC DISCHARGERS
Static dischargers are commonly known as static
wicks or static discharge wicks. They are used on
aircraft to allow the continuous satisfactory operation
of onboard navigation and radio communication
systems. During adverse charging conditions, they
limit the potential static buildup on the aircraft and
control interference generated by static charge. Static
dischargers are not lighting arrestors and do not
reduce or increase the likelihood of an aircraft being
struck by lightning. Static dischargers are subject to
damage or significant changes in resistance
characteristics as a result of lightning strike to the
aircraft, and should be inspected after a lightning
strike to ensure proper static discharge operation.
Static dischargers are fabricated with a wick of
wire or a conductive element on one end, which
provides a high resistance discharge path between the
aircraft and the air. See figure 2-56. They are
attached on some aircraft to the ailerons, elevators,
rudder, wing, horizontal and vertical stabilizer tips,
etc. Refer to your applicable aircraft’s MIM for
maintenance procedures.
