e. Maintenance
requirement:
A
brief
description of each maintenance require-
ment.
f. Periodicity code: Shows how frequently
the maintenance is to be performed.
g.
Rate
(skill
level):
Identifies
the
recommended skill level of the person(s)
considered capable of performing the
maintenance
requirement.
Qualified
personnel
other
than
the
rate/rating
specified may be assigned. When a Navy
Enlisted Classification (NEC) is assigned,
substitution of other personnel is not
allowed.
h.
Man-hours (MH): Total time required to
do the maintenance.
i.
Related maintenance.
(1) Mandatory
(2) Convenience
(3) None
j.
Scheduling aids: Amplifying instructions,
if needed, are located in the maintenance
requirement description block.
k.
SYSCOM MIP control number.
l.
Inactive equipment maintenance (IEM):
Maintenance performed when specific
equipment will remain inactive for 30 days
or longer and is not scheduled for repair,
maintenance, or overhaul by either the
ship's force or an external repair activity.

The Departmental Master PMS Manual also
includes a MIP to Workcenter File (fig. 7-3).
WORKCENTER PMS MANUAL
The Workcenter PMS Manual contains only the
planned maintenance requirements applicable to a
particular workcenter. It is designed to provide a ready
reference of planned maintenance requirements for the
workcenter supervisor and should be retained in the
working area, near the Weekly PMS Schedule, in the
holder provided.
Maintenance Requirement Cards (MRCs)
Maintenance Requirement Cards (MRCs) (fig. 7-4)
provide the detailed procedures used to perform a
maintenance action and state who is to perform the
maintenance and what is to be done, and when, how,
and with what resources a specific requirement is to be
accomplished.
MRCs
contain
the
following
information and instructions:
SHIP
SYSTEM,
SYSTEM,
SUBSYSTEM,
EQUIPMENT.—These
blocks
contains
the
identification of the ship system (functional group),
system, subsystem, or equipment involved.
MRC CODE.—The MRC code consists of two
parts. The first part of the MRC code is the MIP series
code. MRCs applicable to more than one MIP series
will have each MIP series entered in this block. If more
than four MIP series apply, reference will be made to a
note in the Procedure block. The second part is the
maintenance requirement periodicity code. The only
authorized periodicities are listed in Table 7-1.
The periodicity code also includes a number for
specific identification. When more than one MRC of
the same periodicity exists in the same MRC set, the
MRCs, in most cases, will be numbered consecutively;
for example, D-1, D-2, D-3, or M-1, M-2, M-3. An
existing MRC may be reapplied to a revised MIP even
though the periodicity code of the reapplied MRC may
not fall within the normally sequential numeric
periodicity codes. For example, W-1, W-2, W-3, and
W-6 may appear on a MIP, since W-6 was an existing
MRC that was reapplied to this equipment. Technically,
valid MRCs will not be reprinted merely to change the
periodicity code number. Nonsequential numbers will
not affect scheduling or management control.
Dual periodicity codes are used when con-
figurations or utility differences of a permanent nature
exist
between
installations
of
the
same
system/equipment. A dual periodicity may be assigned
if no other aspect of the MRC requires modification to
fit both periodicities. For example, equipment installed
in an SSN or in a surface unit may see daily use, while
the same equipment installed in an SSBN may be idle
for long periods of time because of the nature of the
ship's mission. This long period of idleness may result
in
less
frequently
performed
maintenance
requirements. In this case a dual periodicity, such as
M-1/Q-I or Q-1/S-2, may be assigned. When dual
periodicities are assigned a note on the MIP and the
MRC will specify the frequency of maintenance, for
example, "NOTE: SSBN, schedule quarterly; all others
schedule monthly." The unrequired periodicity should
be deleted by having a line drawn through it.
