technical agent, for each subsystem to be evaluated during a
design review.
Each component that provides a control, sensing, or similar
essential function that impacts the operation of the system
(valves, gauges, pressure regulators, etc.,) should have a unique
identifier made up of a system designation and a number. A table
should be provided identifying system designations. These unique
identifiers should be shown on the drawings and should be used in
the operating and emergency procedures.
When the final system design has been approved, a complete set of
product drawings should be produced and distributed as determined
by the Acquisition Manager. Where appropriate, the drawings
should specify any special material control requirements. The
Acquisition Manager should confer with the SCA to determine which
drawings will be required to maintain system certification and
should ensure that those drawings are distributed to the activity
that will operate the system after initial system certification
has been achieved. The system operators will then continuously
keep those drawings current by ensuring that they reflect as-
built system configuration. This may be accomplished by "red-
line" marking of the drawings. Red line drawings must be
officially revised after each system overhaul or major
configuration change, whichever comes first. All drawing
revisions should be formally documented and the reason and
authority for each revision should be explicitly stated on the
drawing. Each component or item on the as-built drawings should
be identified by the manufacturer's model or type number, part
number, vendor identification, applicable military specification,
federal specification or standard as appropriate.
3.2.7
Operability and Maintainability. The criteria and
procedures for which operation and maintenance are based should
be explained and supported by technical manuals and other
documentation. Include emergency procedures.
Operating and Emergency Procedures. The applicant
3.2.7.1
should develop and submit operating and emergency procedures that
cover all foreseeable normal and emergency evolutions the system
may be required to undergo. Refer to par. 3.6 for detailed
requirements concerning operating and emergency procedures.
Maintenance Procedures. The applicant should provide
3.2.7.2
the SCA with formal maintenance procedures for all systems,
subsystems and components within the scope of certification.
This requirement can be met using DOD PMS and pre- and post-
operational procedures. These procedures will be considered in
the certification process as they relate to safe operation of the
system.
