FLUID LEAKAGE
Wetness around seals, gaskets, fittings, or connections indicates leakage. A stain also denotes leakage. If a fitting
or connector is loose, tighten it. If a fitting or connector is broken or defective, repair it.
Leak Definition for PMCS
CAUTION
Operation is allowable with class I and II leakage. However, any wetness or leakage of fuel is
classified as a class III leak and the TQG must be shut down immediately and the problem
corrected. All other class III leaks must be repaired immediately or reported to your supervisor.
When operating with class I or class II leaks, check fluid levels more frequently. Failure to do this
will result in damage to the 100 kW TQG.
1. Class I - Leakage indicated by wetness or discoloration, but not great enough to form drops.
2. Class II - Leakage great enough to form drops, but not enough to cause drops to drip from item being
checked/inspected.
3. Class III - Leakage great enough to form drops that fall from the item being checked/inspected.
INSPECTION
Look for signs of a problem or trouble. You can feel, smell, hear, or see many problems. Be alert when in or around
the TQG.
Inspect the TQG to see if items are in good condition. Are they correctly assembled, stowed, and secured;
excessively worn, leaking, or corroded; or properly lubricated? Correct any problems found or notify DS
maintenance.
There are some common items to check all over the TQG. These include the following:
