SPECIAL INSTRUCTIONS - CONTINUED
5. Hoses and fluid lines: Look for wear, damage, and leaks, and make sure clamps and
fittings are tight. Wet spots show leaks of course. But a stain around a fitting or
connector can mean a leak. If a leak comes from a loose fitting or connector,
tighten it. If something is broken or worn out, report it to organizational
maintenance.
It is necessary for you to know how fluid leakage affects the status of your vehicle. The
following are definitions of the types/classes of leakage you need to know to be able to
determine the status of your vehicle. Learn and be familiar with them, and remember - when in
doubt, notify your supervisor!
Leakage Definitions for Operator/Crew PMCS
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 being checked/inspected.
Class Ill
Leakage of fluid great enough to form drops that fall from the item
being checked/inspected.
CAUTION
When operating with class I or II leaks, continue to check fluid levels in addition to
that required in PMCS. Parts without fluid will stop working and/or cause damage to
the parts.
NOTE
Equipment operation is allowable with minor leakage (class I or II). Consideration
must be given to the fluid capacity in the item being checked/inspected. When in
doubt, notify your supervisor.
