pressure tubing, and electrical circuits.
Cleanliness as it relates to maintenance must be
considered from the standpoint of its effect upon the proper functioning of
Uncleanliness may conceal deficiencies and shortcomings
resulting in further damage to the item.
Functional surfaces should be
generally free of foreign matter so that cracks, dents, corrosion, or rust
can be readily detected, and so that it will not interfere with the proper
operation or function in areas such as metal-to-metal bearing surfaces,
filters, or areas requiring lubrication.
Fuel and lubricant leaks create
safety hazards. The accumulation of foreign matter, grease, and oil cannot
be tolerated in areas subject to fire.
Equipment Records. Records must be up-to-date, legible, accurate, and
must indicate the true status.
Outstanding MWOs, other deferred
maintenance, and the amount of uncorrected faults, along with the supply
action and timely scheduling of maintenance, can be determined from
equipment records as an indicator of the quality of maintenance.

Lubrication. Lubrication orders should be on hand and in active use.
No evidence of grittiness or binding should be evident in bearings or areas
requiring lubrication. Grease fittings should be clean and clear, and the
proper tools should be on hand.
Safety Features. Compliance with commonsense safety requirements is a
sound indicator of a good PM program. Fire extinguishers, emergency exits,
and safety devices should be easily accessible and conspicuously marked.
Containers for poisonous or flammable liquids must be isolated and properly
Electrical grounding systems must be of an approved type, in
place, secure, and provide a positive ground. Warning systems, buzzers, or
lights should be tested to ensure proper operation.
Observe for the
presence of protective clothing, guards, shields, or screens, where
appropriate, to preclude injury.
