Conducting interference tests to determine if
operating the equipment causes problems with other
installed electronic equipment or if it is hampered by
interference from other electronic or nonelectronic
equipment. The interference tests also identify the
source and amplitude of interference emanating from
nonelectronic equipment.
Listing all approved modifications required

Physical Inspections
Physical inspections include visually inspecting
and determining the condition and adequacy of all
equipment, cabling, repair parts, and tools.
Maintenance Administration Inspections
Maintenance administration inspections determine
if there is an established procedure for submitting a
Ship’s Maintenance Action Form (OPNAV 4790/2K)
and a Ship’s Configuration Change Form (OPNAV
4790/2CK).
Checks are also made to ensure that there is a
procedure for listing field changes on field change
plates and updating electronics publications.
These inspections include, but are not limited to,
checking to determine if the quantity and rates of elec-
tronics personnel on board meet the ship’s allowance
and if the electronics personnel assigned to the ship
are capable of supporting the allowed equipment.
They are also used to determine if there is an estab-
lished program for on-the-job training (OJT), as well
as a program for sending personnel to fleet and
NMPC-controlled electronics schools.
PREOVERHAUL TESTS
AND INSPECTIONS
Preoverhaul tests and inspections (POT&Is) are
held approximately 10 to 12 months before an over-
haul. These inspections cover work on combat system
items to be done during the upcoming overhaul. They
provide information that is used to develop the plans
for the ship’s overhaul.
Personnel performing these inspections are
normally from the ship’s home yard. Personnel from
the Naval Space and Warfare Command (NAVSPA-
WARCOM) or the Naval Sea Systems Command
(NAVSEASYSCOM) may also perform part of these
inspections.
POSTOVERHAUL INSPECTIONS
Postoverhaul inspections furnish the commanding
officer of the ship a report on the condition, capabili-
ties, and limitations of the shipboard equipment and
systems. These inspections include new installations
of equipment and systems, as well as the equipment
or systems that were included in the overhaul job
orders.
MAINTENANCE AND MATERIAL
MANAGEMENT RESPONSIBILITIES
By this point in your career, you probably have
an extensive knowledge of the maintenance and mate-
rial management (3-M) systems. You should follow
those requirements automatically. However, as an FC1
or FCC, you should know the full use of the 3-M sys-
tems and must ensure that your personnel comply with
the requirements.
Maintenance periods and overhauls are scheduled
at various times according to the needs of the ship,
the fleet, the type of ship, and the available funds.
Regular overhauls are normally scheduled approxi-
mately every 60 months. Alterations are any changes
made to improve the military or technical aspects of
a ship.
The required heavy maintenance and overhauls
that cannot be accomplished while the ship is under
way usually takes from 2 to 6 months. During this
time, many new electronics installations and equip-
ment or system overhauls may be completed with the
assistance of yard, tender, or civilian contract per-
sonnel.
