PLANNED MAINTENANCE SYSTEM
provide enough information for the CSO to develop the
mission summary reports.
The SERT must evaluate, monitor, and report
system status during competitive and fleet exercises.
This includes organizing and instructing observers,
preparing recording forms, defining data requirements,
collecting and evaluating data, and preparing a
composite internal report. These reports should be
limited to an evaluation of combat system materiel and
personnel readiness during the exercise.
ALIGNMENT LOGS
During PMS activities and exercises, the SERT is
responsible for determining the mechanical and
electrical alignment of interrelated combat system
functions. The SERT must also assess the impact of a
misalignment on the mission. When SERT members
brief subsystem and equipment personnel before an
exercise or mission, they must emphasize the need for
caution when making adjustments to equipment
subsystems that may in turn affect the total combat
system alignment. Alignment tests and efforts to
reestablish reference standards are complex and
time-consuming. They frequently require shore
facilities, ideal environmental conditions, and extensive
data collection. Technicians should avoid making
realignments that, because of incomplete or inaccurate
reference data, result in inefficient use of manpower and
resources. Experience has shown that unnecessary
alignment efforts can be avoided if reference data are
kept current, accessible, and in a form that can be
interpreted by all team members. Therefore, a combat
system alignment smooth log (if not already in effect)
must be maintained and kept current and accurate. A
total combat system alignment manual for the class of
ship (with combat system) should be available (separate
from CSTOM). The manual should explain the purpose
of total combat system alignment, provide management
data needed for the analysis and troubleshooting of
alignment problems, and provide step-by-step
procedures needed for combat system alignment.
INTEGRATED MAINTENANCE
CONCEPTS
This section of the chapter describes the planned
maintenance system (PMS) as it relates to the
maintenance documentation of a typical integrated
combat system.
Combat system readiness requires efficient main-
tenance. The key to this capability is an organized system
of planned maintenance that is designed to ensure the
maximum operational readiness of the combat system.
The OPNAVINST 4790.4, Ships’ Maintenance and
Material Management (3-M) Systems, sets forth an
effective PMS and assigns PMS management
responsibility.
The PMS provides regularly scheduled tests to
detect degraded performance and prevent failures
(preventive maintenance) during tactical operations.
When failures occur during combat system operations,
the PMS provides a formal step-by-step fault isolation
and repair procedure (corrective maintenance).
Complete technical documentation, including combat
system, subsystem, and individual equipment manuals,
is an integral part of the PMS. These manuals provide
the necessary information for understanding, operating,
and maintaining the combat system.
Shipboard maintenance falls into the three
following categories:
1.
2.
3.
Maintenance within the capability of ship
personnel (organizational level)
Maintenance requiring assistance from outside
the ship (intermediate level) such as a tender or
mobile technical unit
Maintenance requiring port facilities (depot
level) such as shipyard maintenance
Since the goal of PMS is to perform maintenance
on the organizational or intermediate level, depot level
maintenance is not reflected in PMS.
The PMS is a planning and control system that
prescribes a logical and efficient approach to complex
mechanical, electrical, and electronic maintenance. The
PMS was developed to provide supervisors at each
maintenance level with methods for effectively
planning, scheduling, and controlling shipboard
maintenance. It includes a maintenance data collection
system used to record important scheduled and
corrective maintenance information, and electronic data
processing capabilities used to retrieve this information
for maintenance analysis.
You should already be familiar with the 3-M
Systems at this point in your career as an ET; however,
we will summarize the planned maintenance system and
will then add information on the integrated combat
system concept.
