2-5. GENERAL PMCS PROCEDURES (Con't).
(6) Air and Hydraulic Hoses and Lines. Look for wear, damage, and signs of leaks. Ensure that
clamps and fittings are tight. Wet spots indicate leaks, of course, but a stain around a fitting or connector can also
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
your supervisor.
(7) Fluid Leakage. It is necessary for you to know how fluid leakage affects the status of your dolly set.
The following are definitions of the types/classes of leakage you need to know to be able to determine whether or not
the dolly set is mission-capable. Learn and be familiar with them, and remember - when in doubt, notify your
supervisor!
Equipment operation is allowable with minor (Class I or II) leakage. Fluid levels in an
item/system affected with such leakage must be checked more frequently than
required in PMCS. Parts without fluid will stop working or may be damaged. When in
doubt, notify your supervisor. IMMEDIATELY report Class III leaks to Unit
Maintenance.
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 the item being inspected.
Class III . . . . . . Leakage of fluid great enough to form drops that fail from the item
being inspected.
