hen you remove the
radio for maintenance or
to work on other compo-
nents, the pulling and tug-
ging can strain and break
the cable’s shielding.
If that happens, you
may lose communication,
plus exposed wires will let
radio frequencies interfere
with the wire bundles for
the automatic flight con-
trol system (AFCS).
the antenna
cable on the
Chinook’s
AN/ARC-186
radio is a
short
one.
There’s only
one good way
to stop that
tug of war,
aircraft
repairmen!
I t-t-told
you this
c-c-could
hap-pen!
That could mean uncommanded movements
in the aft end of the aircraft during flight or
on the ground during runups.
Let
go!
no!

Let
go!

Pull and
check cable
connectors
for proper
installation
So get your avionics shop
to make a 6-inch extender
with matching
male
and
female
connectors.
While you’re checking out the cable, check the following items that can also interfere with
radio communication.
✔
Make sure the antenna cable connector plug body locks onto the radio AM jack J4. The
pulling and tugging can loosen the connector.
✔
Make sure the connector is installed properly on the cable. Otherwise it won’t mate prop-
erly with the receiver jack’s contact.
✔
Make sure the connector’s nuts are torqued to 9 to 11 in-lbs. Hand tight won’t do.
