EQUIPMENT NOT READY/AVAILABLE IF
This column lists the criteria that will limit the use of equipment or make it not ready for use. Depending on the
severity of the limitation, the MSD may not be able to operate and perform its primary mission. The terms "ready/
available" and "mission capable" refer to the same status: Equipment is on hand and can perform its combat
mission. If tools required to perform PMCS are not listed in the work package, notify unit maintenance. Write up
items not fixed on DA Form 2404 for unit maintenance. For further information on how to use this form, see DA
DOCUMENTATION OF PMCS ITEM FAILURES
PMCS item failures are to be recorded on DA Form 2404, Equipment Inspection and Maintenance Worksheet,
and forwarded to unit maintenance via the vessel's chief engineer. Documentation of PMCS item failures must
include the compartment location and item number within the work package to ensure proper dissemination. All
corrected faults will be recorded on DA Form 4640 (Harbor Boat Deck Department Log for Class A&B Vessels)
and DA Form 4993 (Harbor Boat Engine Department Log for Class A and C-1 Vessels). All uncorrected faults will
be transcribed to a DA Form 2407, Maintenance Request, and the appropriate log entry must be made. The crew
will service the LT as outlined by the intervals contained in the PMCS tables.
CORROSION PREVENTION AND CONTROL (CPC)
Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any corro-
sion problems be reported so that they can be corrected and improvements made to prevent future problems.
Corrosion is typically associated with rusting of metals, but it can also include deterioration of other materials,
such as rubber and plastic. Unusual cracking, softening, swelling, or breaking of materials may indicate a corro-
sion problem. Suspected corrosion problems should be reported using SF 368 (Product Quality Deficiency
Report). Use of key words such as "corrosion," "rust," "deterioration," or "cracking" will ensure that the informa-
tion is identified as a CPC problem.
Equipment operation is allowable with minor leakages (Class I or II) except for fuel
leaks. Of course, consideration must be given to the fluid capacity of the item or system
being checked. When in doubt, ask your supervisor.
When operating with Class I or II leaks, continue to check fluid levels as required in your PMCS. Class III leaks
should be reported immediately to your supervisor. It is necessary to know how fluid leakage affects the status of
the MSD. The following are definitions of the classes of leakage an operator or crewmember needs to know to be
able to determine the condition of the leak. Learn and then be familiar with them. When in doubt, ask your
LEAKAGE CLASSIFICATIONS I, II, III
Leakage classifications. Leakage definitions for operator/crew PMCS shall be classified as follows:
1. Class I: Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops.
2. Class II: Leakage of fluid great enough to form drops but not enough to cause drops to drip from the item
3. Class III: Leakage of fluid great enough to form drops that fall from the item being checked/inspected.
