The OPNAV 4790/CK form is completed to the
maximum extent possible by the accomplishing
activity and provided to the ship or activity 3-M
The 3-M coordinator then reviews the forms for
legibility (all copies) and ompleteness and provides the
forms to the applicable workcenter supervisor, who
ensures that the proper documentation is completed and
accomplished, including required signatures to indicate
verification of all reported configuration changes.
The ship is also responsible for reporting and
monitoring all changes accomplished by ship's force
during any type of availability, and for providing the
Configuration Change Form to the overhauling activity.
The ship is not responsible for reporting configuration
changes accomplished by an overhauling activity
accomplishment of any action prescribed by an
alteration directive (SHIPALT or equipment alteration)
or (2) the installation, removal, or modification of any
replacement of repair parts (such as nuts, bolts, wires,
0-rings, gaskets, resistors, and capacitors) with like
parts, does not constitute a configuration change.
The OPNAV 4790/CK form is used to report a
configuration change or to report the completion of a
previous deferral that resulted in a configuration
change. Deferred maintenance actions and completed
maintenance actions that do not result in configuration
changes are reported on OPNAV 4790/2K. The
OPNAV 4790/2K form will never be used to report
accomplishment of any maintenance action that results
in configuration changes.
A configuration change occurs whenever the
accomplishment of a maintenance action results in the
Addition or installation of any new equipment.
Deletion, removal, or turn-in of any installed
Replacement or exchange of any equipment. A
replacement or exchange is reported as the
removal of an installed item of equipment and

CAUTIONS ON ERRORS
Since the data entered on the MDS forms is used by
data processing equipment to provide information to a
ship in the form of the CSMP report, it is essential that
each form be filled in completely and accurately. A
computer cannot recognize anything that it is told does
not exist. It will reject incorrect and incomplete entries
and the data will not be available for use. To prevent this
from happening, it is important that the completed
forms be reviewed at all levels. Some of the common
errors that workcenter supervisors, division officers,
department heads, and 3-M coordinators should be alert
omission of slash marks through zeros and Z's;
use of improper codes for alterations and field
too many or not enough spaces between words
in the Remarks section;
incorrect dates; and
These are only a few of the many errors detected
each day by a typical TYCOM 3-M staff section.
Some areas on the 4790/2K require special
mention. Alterations and field changes are identified in
block 18 by a two-letter code in the first two spaces,
followed by the identification number of the change. A
title code, such as A, D, F, or K may be shown in the
authorizing directive of SHIPALTs. This title code, if
assigned, must be entered in the extreme right hand
position of the block.
