Configuration Change Form
On board ship it is very important for the
equipment technicians to submit a CCF for any
changes or modifications to their equipment. This
also includes any discrepancies in preventive
maintenance. These technicians basically know
when something is not right with their equipment.
The leading Storekeeper or chief should also be
aware of any changes that take place on board.
You have to make sure the various departments
submit a configuration change if they want you
to support them with the necessary repair parts.
The importance of configuration change
reporting cannot be overemphasized. You have
to make sure these various work centers submit
the changes. By submitting the CCF, these centers
will help improve the supply and maintenance
support to their own ship and to the fleet.
The responsibility of identifying and reporting
configuration changes rests with all levels of
command. Whenever new equipment is installed
aboard ship, whether it is during an overhaul,
done by ships force, or done by an outside
activity, you should make sure a configuration
change is submitted. From some of these activities
you will hear We will submit the configuration
changes for you. Do not accept this as hard fact.
You should personally ensure submission of a
configuration change so that you will get the
When a work center fills out a configuration
change, it has to be screened by the supply
department for completeness. You also have to
complete various blocks on the form. After you
complete the form, it should be forwarded to the
ships 3-M coordinator for submission to the
TYCOM. To understand the proper procedures
for filling out and submitting a change, you
should see the ships 3-M Manual, OPNAVINST
4790.4. See figures 2-7 and 2-8 for examples of
two different OPNAV Form 4790/CK usages.
A variety of COSAL correspondence is
directed to every ship. Most of the correspondence
is directed to the supply department; for example,
APL revisions based on CASREP and 3-M usage
data from the fleet, TYCOM class allowances,
change reports, and ships allowance change
reports. When this type of correspondence comes
in, you should make sure changes to the COSAL
are made and the necessary repair parts are
ordered for stock.
Other less obvious but still important
correspondence is generally not associated with
supply, but you should make sure all COSAL
correspondence is routed via the supply
department so that the necessary changes can be
promptly made. These types of changes often
include ORDALTs, SHIPALTs, and hardware
systems command letters.
REQUESTS FOR APLs AND AELs
Occasionally, you will need copies of APLs
or AELs that are missing, mutilated, or illegible.
Also, when an initial or revised APL or AEL for
a newly installed or modified equipment has not
been received, you can request it from the nearest
supply center, tender, shipyard, or from the
cognizant TYCOM. If you are not near any of
these activities, you can request a copy of the APL
from the Ships Parts Control Center (SPCC),
Mechanicsburg, Pennsylvania. You can do this
by phone, message, speedletter, or use the
NAVSUP Form 1220-1.
SHIPS OPERATING CYCLE
Completing a regular overhaul or a complex
overhaul triggers the start of a ships overhaul.
The ships operating cycle is defined as the period
between overhauls and includes periods of
Reporting procedures are different during
availabilities and, therefore, are addressed under
shipyard availability period not including the
integrated logistics overhaul (ILO).
During the operating cycle, the ships
responsibility is to report, inquire, or request
equipment/component or equipage changes
detected or accomplished by the ships force, a
tender, an intermediate maintenance activity, or
an alteration installation team. Any team that
