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 LT 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 PAM 738-750.
DOCUMENTATION OF PMCS ITEM FAILURES
PMCS item failures are to be recorded on DA Form 2404, Equipment Inspection and Maintenance Worksheet, and for-
warded to unit maintenance via the vessel's chief engineer. Documentation of PMCS item failures must include the com-
partment 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 corrosion
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 corrosion 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 information is identified as a CPC problem.
LEAKAGE DEFINITION
! CAUTION
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 LT. 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 supervisor.
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 being
checked/inspected.
3.
Class III: Leakage of fluid great enough to form drops that fall from the item being checked/inspected.
