technical requirements and that repaired
equipment performs satisfactorily.
Quality control: The management practices that
promote quality repairs.
Acceptance: When an authorized representative
approves specific services rendered such as a
repair or manufactured part.
Calibration: The comparison of two instruments
or measuring devices, one of which is a standard
of known accuracy traceable to national
standards. The purpose is to detect, correlate,
report, or eliminate by adjustment any
discrepancy in the accuracy of the instrument or
measuring device being compared with the
Inspection: The examination and testing of
components and services to determine whether
they conform to specified requirements.
In-process inspection: An inspection done
during the manufacture or repair cycle to
measure results. It is also done to identify
production problems or material defects that
cannot be detected when the job is complete.
Inspection record: Contains the data compiled
during an inspection.
Specifications: Any technical or administrative
directive, such as an instruction, a technical
manual, a drawing, a plan, or a publication, that
defines repair testing or performance criteria.
QA audit: A periodic or special evaluation of
practices, plans, policies, procedures, products,
directives, and records necessary to determine
how work is being done. The audit results are a
tool for improvement.
Level I material: Material that has been certified
as to its material and physical properties as well
as traceability to the manufacturer by a qualified
certification activity. This material has a MIC
number assigned along with a certification
document. It is destined for a level I system, as
defined in the MIC manual, and requires special
Controlled material: Any material that must be
accounted for and identified throughout the
manufacturing or repair process.
Controlled work package (CWP): An assembly
of documents identified by a unique serial
number that may contain detailed work
procedures, purchase documents, receipt
inspection reports, objective quality evidence,
local test results, and any tags, papers, prints,
plans, and so on, that bear on the work performed.
(See more information later in the chapter.)
Levels of assurance: A systematic review of
quality control records and all production actions
to provide accountability that work performed or
material manufactured will perform as expected
and that there is documentary evidence to support
that expectation. (See more information later in
Departure from specification: A lack of
compliance with any authoritative document,
plan, procedure, or instruction. (See more
information later in the chapter.)
Procedure: A written instruction used in
production and repair, giving all essential
elements and guidance necessary to produce
acceptable and reliable products.
Process: A set of actions written in a special
sequential order by which a repair or
maintenance action, a test, or an inspection is
done using specific guidelines, tools, and
Reliability: The probability that an item will
perform its intended function for a specified
interval under stated conditions.
SUBSAFE: An acronym for the Submarine
Safety Program that provides a high level of
confidence in the material conditions of the hull
The Controlled Work Package
The CWP provides QC requirements and
procedures to help ensure that fabrication or repair will
produce a quality product. These requirements or
procedures include both TYCOM and local
command-generated information for processing and
sign-off. The typical CWP will have QA forms,
production task control forms, QC personnel sign-off
requirements, and hydro or test forms. Each CWP
covers the entire scope of the work process and is able
to stand on its own. The job control number (JCN)
provides traceability from the work package to other
