Introduction. This section defines the two elements
of general maintenance, scheduled maintenance and unscheduled
maintenance, and outlines the objectives for each.
maintenance concepts are also briefly addressed.
Scheduled Maintenance. Scheduled maintenance is all
maintenance which is scheduled and performed on equipment,
components and systems prior to anticipated failure or operational
degradation below acceptable standards/criteria.
maintenance actions are the minimum required to maintain equipment
in a fully operable condition, and within specifications. W h e n
performed according to schedule, these scheduled maintenance
actions will provide the means to identify parts requiring
replacement prior to failure and are, therefore, preventive in
nature. Scheduled maintenance is intended to prevent equipment,
component and system failures which might otherwise result in
repeated unscheduled (corrective) maintenance actions.
The primary objective of scheduled maintenance is to provide
for managing and conducting maintenance in a manner which will
ensure maximum operational readiness of the man-rated hyperbaric
facility. Therefore, scheduled maintenance shall be established
to meet the following intermediate objectives:
specifications and criteria including
Effective use of available manpower
resources in maintenance and maintenance support.
Documenting of information relating to maintenance and
maintenance support actions.
Improvement of maintainability and reliability of
systems, equipments and components by provision of documented
maintenance information for analysis.
Identification and reduction of the cost of maintenance
and maintenance support in terms of manpower and material
Provide the means to properly schedule, plan, manage, and
Collect data on which to base improvements in design and
spare parts support.
On applicable equipment, components and systems, commands are
encouraged to make use of the Planned Maintenance System (PMS)
