Procedure Column. This column provides the procedure to check or to service the item(s) listed in the
Equipment Not Ready/Available If: Column. This column tells you what faults will keep the trailer from
being capable of performing the primary mission. If you perform check and service procedures that show
faults listed in this column, do not operate the trailer. Follow standard operating procedures for maintaining
the trailer or reporting equipment failure.
It is necessary for you to know how fluid leakage affects the status of the trailer. The following are
definitions of the classes of leakage you need to know to be able to determine the status of the trailer.
Learn these leakage definitions and REMEMBER - WHEN IN DOUBT, REFER TO NEXT MAINTENANCE LEVEL.
Equipment operation is allowable with minor leakages (Class I or II). Consideration must be given to the
fluid capacity of the item or system being checked. When Operators are in doubt, refer to Field Level
When operating with Class I or II leaks, continue to check fluid levels as required in your PMCS.
Operators must report Class III leaks to Field Level Maintenance. Failure to comply may result in damage to
CLASS I - Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops.
CLASS II - Leakage of fluid great enough to form drops but not enough to cause drops to drip from item
CLASS III - Leakage of fluid great enough to form drops that fall from the item being checked.
Look for signs of a problem or trouble. Senses help here. You can feel, smell, hear, or see many problems.
Be alert when on the trailer.
Inspect to see if items are in good condition. Are they correctly assembled, stowed, and secured, or
excessively worn, leaking, corroded, or improperly lubricated? Correct any problems found or notify the next
level of maintenance.
