This document provides guidance on the Planned Maintenance System (PMS) used by the Navy to manage shipboard maintenance. It describes the key elements of the 3M system including Maintenance Requirement Cards, Equipment Guide Lists, feedback reports, and responsibilities of personnel involved in maintenance from the Commanding Officer to work center maintenance personnel. Safety precautions and procedures for documenting maintenance, reporting discrepancies, and scheduling preventative maintenance are also outlined.

2. Providing maintenance and material
managers the means to plan, acquire,
organize, direct, control and evaluate the
manpower and resources used for the
support of maintenance.
3M is the nucleus for managing
maintenance onboard ships.
103.1

3. a. Standardization - achieve uniform maintenance standards and criteria.
b. Efficiency - effective use of available manpower and material resources
in maintenance and maintenance support efforts.
c. Documentation - recording of maintenance and maintenance support
actions to establish a material history.
d. Analysis - provision to be used in the improvement of maintainability
and reliability of systems and equipment, and the reduction of cost of
material ownership.
e. Configuration Status Accounting - a means of reporting and recording
changes in what equipment is installed onboard, equipment configuration
specifications, and shipboard location.
f. Scheduling - standardized method for scheduling, planning, managing,
and tracking maintenance required and accomplished.
Information collected on completed maintenance and
configuration changes provides the following benefits:

and operating shipboard equipment is required.
* Accidents do not respect persons or rights.
Statistics show that a high percentage of accidents or
casualties could have been prevented if specific
precautionary measures had been taken.
* Every effort has been made to indicate
hazards to personnel in the "Safety
Precautions" block and in the appropriate steps
of the procedure block of MRCs.
WARNINGS WILL BE INSERTED

matters related to PMS.
103.8

42. FBR FORM
Two versions: SKED and Hardcopy
SKED – Instructions are available in the
help file, with some specific Do’s and
Don’ts
Hardcopy - composed of an original and
four copies. Instructions for preparation
and submission of the form are printed on
the back of the last copy.

43. Category A -- This type of FBR
is non-technical in nature and is
intended to meet PMS needs
which do not require technical
review. Category A FBRs are
submitted to request classified
or other PMS documentation
which cannot be obtained
locally.
There are three types of FBRs:
Category A, Category B, and Urgent.
103.8

44. This type of FBR is technical in
nature, and is used to report:
Technical discrepancies inhibiting PMS
performance.
Shift of maintenance responsibilities.
Requests for TYCOM assistance.
Category B --
103.8

45. When the reason for submission of a PMS FBR
involves safety of personnel, ship, or equipment
and relates to the technical requirements of PMS,
the FBR will be considered URGENT.
The message shall describe the unsafe procedures
or conditions, and shall identify the MIP/MRC
involved.
URGENT Feedback Reports.
103.8

46. TMDER
Used to correct Technical Manuals and
Publications used in the maintenance of

the back of the Manual.

47. CONFIGURATION
Known as:
4790/CK, Configuration Change, & Configuration
Items
Used to get support for newly installed equipment.
Will initiate all logistics:
PMS, Parts, & Technical Documentation
NOTE: FBR’s can be used to start and change PMS, but will
do nothing for the other elements of logistic support.
