The applicant should ensure that all documentation required to
support design, material selection, work procedures, tests and
inspections are prepared and maintained in accordance with the
requirements of Section 2 and Appendix C.
For major modifications due to system alterations, the
Acquisition Manager should ensure that applicable fabrication and
test documentation (i.e., drawings, technical manuals, test
memoranda, etc.,) are revised and then reviewed by the SCA. For
repairs, the responsibility for updating this documentation lies
with the applicant.
5.7
Procedures. Those procedures required to perform work,
inspection and testing should meet the requirements set forth in
Section 3.3 and be so specified in contract documents. These
procedures should be available for review and concurrence by the
SCA during on-site surveys.
5.8
Quality Assurance (QA). Quality assurance requirements
during overhaul and repair should be the same as those specified
in par. 3.3.8 of this document and should be specified in
contract documents.
5.9
Re-Entry Control. Particular attention must be
directed to the proper use of approved re-entry control
procedures as described in Appendix C. Re-entry control forms
must be accurately completed and must contain all required
signatures prior to re-entry into a system that is within the
scope of certification. Prior to use of the system, all re-entry
control actions must be satisfactorily completed and signed or
have an approval for a departure from specifications approved.
5.10
Retest Requirements. Repairs and modifications to
systems require the same stringent testing requirements as newly
designed systems. The following guidelines should be used to
determine the level of testing required during systems overhaul
periods:
a) Factory Acceptance Tests will not be required
unless the replacement equipment is of such a specialized nature
that the repair activity is unable to perform testing.
b) Pre-installation tests will be required only for
replaced or repaired components.
c) Pre-operational tests will be required only when a
subsystem is repaired or modified. These tests need to be
performed to ensure that those sections of the system that were
repaired or modified are properly reinstalled.
d) System operational tests should be conducted on all
subsystems that have been repaired, modified or placed in lay-up
when time permits and personnel are available. The extent of
system operational testing may be negotiated with the SCA.
