Fabrication and assembly documentation
j) Any other processes, procedures, or instructions
required for construction of the unmanned pressure test facility
Adequacy of these processes must be substantiated by a history of
satisfactory use or by documented qualifications and tests.
Fabrication/Assembly Procedures. Fabrication/assembly
procedures must define the scope of work and provide production
personnel with step-by-step instructions on how the work is to be
accomplished. When fabrication/assembly procedures are written
to accomplish repairs, maintenance or modifications, they should
state the specific reason for performing the work. These
instructions are required wherever fabrication, assembly,
cleaning and/or testing of components or systems, within the SOC
boundaries, is to be performed during initial certification.
Fabrication/assembly procedures should also provide all
inspection and retest requirements and any warnings or cautions
that must be observed while performing the work.
Fabrication/assembly procedures should be generated prior to
commencing work. Where work procedures already exist (e.g.,
technical manuals, standard process instructions, approved
drawings, PMS, etc.,), the specific paragraphs from those
documents should be called out in the fabrication/assembly
procedure. The person responsible for the work, inspections and
retest of the system or component should sign each work
procedure. Any change to the scope of work being performed
should cause a revision to the fabrication/assembly procedure to
be issued. All fabrication/assembly procedures should be made
available to the SCA for review during on-site surveys.
Process Instructions. Process instructions are those
standardized procedures that have been developed by a production
activity for work that they commonly perform. To be used in a
fabrication/assembly procedure, the process instruction must
provide step-by-step instructions for accomplishing the work.
All process instructions that the production activity intends to
use during fabrication or repair of an unmanned pressure test
facility should be provided to the SCA for review. In some
cases, (e.g., welding, brazing, NDT and cleaning), the SCA or his
designated representative must approve process instructions prior
