maintained so that all systems, subsystems, and components within
the SOC are functioning properly, in an as-certified condition,
prior to each operational use.
All work and testing accomplished during routine repairs and
maintenance should be in accordance with the requirements in
Section 5. Only qualified personnel should perform repairs,
maintenance, inspections and testing. Documentation requirements
for repairs, non-routine maintenance, and testing should be
recorded in accordance with the requirements of Appendix C.
2.9.2.3
System Certification Survey. A system certification
survey, as described in par. 2.5, may be performed when deemed
necessary by the SCA as a condition of sustaining or continuing
system certification. Unsatisfactory survey results may result
in termination or suspension of system certification.
Operating Limits. The system should be operated only
2.9.2.4
within its certified operational limits. Operation outside of
the authorized limits without a valid waiver is not allowed and
may result in termination or suspension of system certification.
Any violation should be immediately reported to the SCA, stating
the cause or justification.
Unusual Situations. The SCA should be advised of any
2.9.2.5
situation, which may prevent the system from maintaining its
intended operational capability. These may include, but are not
limited to, exceeding certified pressure, physical damage, fires,
emergency pressure excursions, and casualties resulting in injury
or death. Further, a report should be submitted containing an
evaluation of the extent of damage, proposed repair methods, and
probable cause of the emergency (e.g., personnel error, nature of
the operations, system or component failures, etc.,). It is not
intended that these emergency situations include failures that
only temporarily interrupt the operational capability of the
system and are corrected by routine repairs.
Continuation of System Certification. Continuation of
2.9.3
system certification is an extension by the SCA of the
certification period beyond that initially granted. This is
normally done to permit continued use of a system that has had no
changes to the basic design, SOC, or general operating
characteristics and where the material condition of the system
will support the continuation. During this continuation of
system certification, all requirements noted in par. 2.9.2 should
be observed. The applicant should arrange with the SCA for a
continuation of certification and should submit a request for an
on-site survey no less than 90 days prior to the desired
certification date.
Re-certification. Re-certification is a new
2.9.4
certification of a system where the existing certification has
expired or has been terminated. To re-certify a system, the SCA
