The maintenance control board contains the cycle
schedule and the current and subsequent quarterly
schedules. The board summarizes the status of current
and planned combat systems preventive maintenance.
It is updated weekly by the division officer for all
deferred and completed maintenance items.
This subsection describes the maintenance index
page and the cycle, quarterly, and weekly schedules.
Maintenance Index Page
The maintenance index page (MIP) contains a
brief description of the requirements on the main-
tenance requirement card for each item of equipment,
including the periodicity code, the man-hours in-
volved, the minimum required skill level, and, if ap-
plicable, the related maintenance requirements. The
MIPs for all equipments in a department are main-
tained in the departments master PMS record, the
record that is used by the department head to schedule
maintenance on the PMS schedule forms. Each work
center has a work-center PMS record that contains the
MIPs applicable to that work center.
The weekly schedule is a visual display that is
normally posted in the working area of each mainte-
nance group. The maintenance group supervisor uses
the weekly schedule to assign specific personnel to
perform maintenance on specific equipment. Assign-
ments include system and equipment tests and service
MAINTENANCE DATA SYSTEM
The Maintenance Data System (MDS) has three
functions. It provides a means of (1) recording main-
tenance actions, (2) processing the recorded data to
define important facts about maintenance and equip-
ment, and (3) retrieving information for analysis.
Significant data identified by the system include the
reason the malfunction occurred and the manner in
which it was discovered, the man-hours expended, the
exact equipment affected, any delays in repair, the
reasons for delays, and the types of maintenance
Recording Maintenance Actions
The cycle schedule is a visual display of pre-
ventive maintenance requirements based on the ships
current overhaul cycle. It is used by department heads
to assist in the quarterly planning of non-PMS-related
activities, such as inspections and training.
The quarterly schedule, planned from the cycle
schedule, is a visual display of the ships employment
schedule. It is prepared by department heads in co-
operation with division officers and maintenance
group supervisors. The schedule shows the current
status of preventive maintenance for each group and
assigns specific requirements in conjunction with the
ships operational schedule.
Maintenance personnel should record (document)
certain shipboard maintenance actions and corrective
maintenance on specific categories of equipment at
the time the maintenance actions are performed or
deferred. Information is recorded and submitted to the
MDS for input on the Ships Maintenance Action
Form (OPNAV 4790/2K).
Processing Recorded Data and
The MDS data-processing facilities collect, store,
and analyze maintenance information inputs into the
system. The MDS yields a data path concerning
equipment maintainability and reliability, man-hour
usage, equipment alteration status, material usage and
costs, and fleet material condition. Various automated
