PROCEDURE
5.1 This procedure documents the system which will identify, segregate (or control if segregation is not practical) and properly dispose of nonconforming product. Corrective and preventative actions will be handled per AP0414.
5.2 Definitions:
5.2.1 Nonconforming Product – Any product, i.e., hardware, components,
subassemblies or final assemblies that do not meet the requirements of the
Engineering Drawing, governing process or material specification or
workmanship standards. May be referred to as Discrepant Material.
5.2.2 MRB – Material Review Board
5.2.3 PMR – Preliminary Material Review
5.2.4 MRB Area – Secure area where nonconforming material is segregated to
preclude unintended use in production.
5.2.5 MRB Roster – A roster identifying individuals authorized to enter the
MRB Area and identifying those having the responsibility to affect and approve
disposition of product processed through MRB.
5.2.6 System – Current ERP or MRP System used to control and monitor product
in the possession of Kavlico.
5.3 Identification and Segregation
5.3.1 All personnel coming in contact with product have the responsibility
to identify nonconformances and initiate a Rejection Report Form, AF017 per
WI006. Personnel initiating the rejection form AF017 shall document the
rejection form number and date in
the relevant operation on the original router.
5.3.2 All Manufacturing and Inspection personnel are responsible to stop the
job and alert Support members of any quality issue. Rejection Form AF017 must
be initiated.
5.3.3 Preliminary Material Review (PMR) of all nonconforming products will be
performed by Cell Support Team. The Cell Support Team should consist of
Quality Assurance, Manufacturing Engineering, Design Engineering, Department
Supervision and others, as needed, to accurately assess the nonconformity. The
Cell Support Team performing PMR may be different individuals than those on
the MRB Roster responsible for Formal MRB activity. However, the disposition
authority on the rejection report will remain with the Quality Eng., Design
Eng., and Manufacturing Eng. members of the team. The Cell Support Team will
determine if the nonconformity can be reworked to Engineering Drawing
Specification or if the material should be rejected to MRB for further
evaluation. If defective material is identified and the Cell Support Team
cannot address it immediately the product must be segregated and CONSPICUOUSLY
IDENTIFIED WITH A RED REJECTION TAG 98-222 or Rejection Report form AF017.
Product awaiting evaluation shall be tagged and separated from good product to
preclude its unintended use until evaluation can be performed. A copy of the
original Router and Rejection Report must remain with the suspect product.
5.3.4 When the Cell Support Team determines that Rework can be performed
without further or
formal MRB activity, the Rejection Report, AF 017, shall be dispositioned
“Rework” and shall have the Manufacturing Engineer, Design Engineer, and
Quality Engineer’s signature of approval. Rework Instructions must be noted on
the Router, or on one of the documented Rework Forms, i.e., AF 144 thru TAB,
added to the Router. Rework documentation becomes a permanent record that
shall remain with the Router at all times.
Rework Instructions must have an Inspection Operation following the Rework to
validate conformance to Engineering Drawing Specification(s).
Note: AF144 thru TAB are standard blank rework forms to be utilized by
the Manufacturing Engineer to provide Rework and Inspection steps necessary to
return the nonconforming product to Engineering requirements. AF144 thru TAB
define specific Rework that may occur more frequently and therefore Rework
Instructions have been permanently documented to expedite the process.
5.3.5 Non-conformances can be identified at a lower level manufacturing
process and the Cell Support Team can determine that Conformity can be or will
be achieved at a higher level manufacturing process, in these cases the Cell
Support Team shall clearly record on the Rejection Report the specific
Operation and Process that will bring the product / feature into compliance.
However, this can only take place if the correction can be made prior to the
product being delivered to Stores. No product shall be in stores when it is
known to be nonconforming.
5.3.6 Product needing further or Formal MRB Processing must be segregated and
moved to the MRB area with the AF017 form completed per WI006.
5.3.7 Red Rejection Tags should accompany suspect product when it has been
determined that Further MRB activity is necessary. If at a later time product
is Reworked to Engineering Drawing Specifications, Scrapped or, is determined
to Conform to Engineering Specifications the Red Rejection Tag shall be
removed and disposed of.
5.3.8 Rejection Reports shall be reviewed and approved by the Cell Support
Team, to ensure the form (AF017) has been properly filled in. The reason for
rejection shall be clearly defined. Any Rejection Report improperly filled out
can be returned to the generating Cell for correction. Rejected product in any
given Cell should be processed within one working day.
5.4 Segregation of Nonconforming Material
5.4.1 All nonconforming products that cannot be Reworked to Specification as
defined in Section 5.3 shall be segregated by being delivered to and retained
within the secured MRB area. Access to this area shall be limited to
authorized MRB personnel and those accompanied by an authorized MRB member.
Those authorized as MRB Members will be identified on a MRB Roster, which
shall be conspicuously displayed in the MRB area.
5.4.2 Product delivered to the MRB area shall be transacted in the System to
ensure its whereabouts is known.
5.4.3 Product being removed from the MRB area temporarily in order to
facilitate some additional action shall be done in accordance with Work
Instruction WI 153 and be recorded on the MRB Log Out Form AF098.
5.4.4 Once disposition has been agreed upon, product will be transacted in the
System to reflect movement to a predetermined location, i.e., scrap, rework,
etc.
5.4.5 MRB shall consider the effects of the nonconformance on other products
and processes during the disposition phase. If it has been determined that
other products or processes are affected, then appropriate actions shall be
planned and implemented to contain the effect of nonconformity.
5.4.6 Rejected items transferred from an alternate site shall be routed to the
MRB Lockup after going through the receiving process, even if marked
“attention to” an individual person.
5.5 Material Review Board (MRB)
5.5.1 The Material Review Board consists of representatives from Manufacturing
Engineering,
Design Engineering and Quality Assurance. Representatives are selected based
on individual required training, product knowledge, and personal experience.
Other cognizant disciplines resources will be called upon as necessary to
support the process..
5.5.2 Personnel qualified for MRB or PMR activities, shall have at least six
months working experience in either quality, manufacturing or engineering,
shall be knowledgeable of the manufacturing processes and attend a training
session of this procedure
5.5.3 MRB and/or PMR personnel shall complete a periodic refresher training to
maintain MRB authority. The training shall be complete every two years minimum
5.5.4 AF275 is the list of formal MRB Members, it is maintained by the Quality
Manager and can be available thru our Document Control system.
5.6 Disposition of Nonconforming Material
5.6.1 All nonconforming material received into the MRB area requires review
and disposition by an MRB member. Required signatures will be as described
within the description of each disposition described below.
5.6.2 Additional approval signatures may be required as defined per Customer
Contract. Review Contracts or MRB Authority list per WI-257. Customers can
disapprove any portion or the entire proposed disposition.
5.6.3 As process owner, Quality Assurance shall be responsible for ensuring
proper documentation and shall be the last person to sign off disposition
after reviewing the rejection report for completeness and accuracy.
5.6.4 Nonconforming material can be dispositioned in one of the following five
ways:
a. Rework – When it is determined that the Product can be made to meet
specification rework should be seriously considered. Rework to design
specifications can be determined during the PMR phase of this process as
described in section 5.3.2 and 5.3.3 of this procedure. Rework instructions
identifying rework performed are required. The disposition shall have the
Design Engineer, Manufacturing Engineer, and Quality Engineer signatures. When
disposition involves special process (i.e. welding or brazing), the applicable
process spec shall be reviewed for limitations on Rework.
b. Use as Is (UAI) – When it is determined that the nonconformity will not
affect Fit, Form, or Function for its intended application. Review No MRB
Authority List (AF326) per procedure WI683.Nonconformities for lower level
components or subassemblies
falling into Type II nonconformity may not require a waiver to be submitted to
the customer. Type I Nonconformities require a waiver to be submitted to the
customer per Paragraph 5.9.1. UAI dispositions require the signature of the
Quality Assurance
representative, the cognizant Manufacturing Engineer, and the Design Engineer.
If the nonconforming part is a purchased part and is determined Supplier
responsibility, the Supplier Quality Engineer will notify Supplier per WI070.
c. Scrap – When it has been determined that the product is unsalvageable a
scrap disposition is chosen. NOTE: Nonconforming Product supplied by an
outside source should not be scrapped against Kavlico, unless it is determined
to be Kavlico’s responsibility. Scrap disposition requires Quality Assurance
representative and the cognizant Manufacturing Engineer and the Design
Engineer signature.
d. Return to Supplier (RTS) – Nonconforming Product received from an outside
supplier should be returned to that supplier for Rework, Scrap, Repair, etc.
at their expense. If it is in Kavlico’s interest to keep the Product and
disposition for internal use, the supplier should be notified, and Corrective
Action Request initiated. Every effort should be made to supply the supplier
with at least one example of the defective material when issuing them a
Corrective Action. RTS dispositions require the signature of the Supplier
Quality Assurance representative, and either the cognizant Manufacturing
Engineer or Design Engineer. Note: Kavlico owned product rendered scrap as the
result of a Process performed by an outside processor, (i.e., heat treaters,
platers, etc. shall not be dispositioned RTS).
e. Conforms – When evaluating the nonconformity and it seems as though the
validity of the Nonconformance is questionable and re-inspection determines
that the Product does meet Engineering Specification(s) a Conforms disposition
is appropriate.
Conform disposition requires the signature of the Quality Engineer, and either
the cognizant Manufacturing Engineer or Design Engineer.
f. Repair – When a product does not meet drawing requirements or spec but can
be made acceptable for the intended use, MRB members: Quality Assurance
representative and the Design Engineer will review and disposition the
nonconformance after obtaining customer approval. Other individuals (including
Manufacturing Engineer) may participate and make recommendations. No repair
dispositions are permitted without prior customer approval.
5.7 Type I Non-conformances (Major)
5.7.1 Any non-conformance that could by itself, or by its relation to other
components, result in failure or malfunction involving the safety of personnel
using or maintaining the item. Any non-conformance that could adversely affect
performance, reliability, durability, interchangeability, replaceability or
otherwise result in failure of the End Item component / assembly. Non-
conformances departing from the contractual or envelope drawing requirements
are also included.
5.7.2 Non-conformances classified as Type I must be coordinated with the
customer. Typically, this will require a Product Waiver, Nonconforming
Material / Variance Authorization to be submitted to the customer.
Note: See paragraph 5.9.1 for details of this process.
5.7.3 Kavlico reserves the right to “Proceed at Risk”, to continue processing
the product through subsequent manufacturing processes in anticipation of a
positive response from the customer. An example of when “Proceeding at Risk”
might be exercised, i.e., when a very important delivery date is fast
approaching, and replacement hardware is not immediately available.
“Proceeding at Risk” should be concurred upon by cognizant manufacturing,
contracts, or program management personnel and shall be approved by the
cognizant Quality Assurance Representative. Records of approval to “Proceed at
Risk” shall be kept with the routing package and as part of the quality
record.
5.8 Type II Non-conformances (Minor)
5.8.1 Any nonconformance representing a departure from Kavlico Type Design
or Standard(s), in a manner, or to a degree which has no significant bearing
on the effective use or operation of the item or related components, and which
does not involve any of the factors listed in the description of the TYPE I
Nonconformance (Major).
5.8.2 MRB Personnel representing Quality Assurance, Manufacturing Engineer,
and Design Engineering must concur with Use As Is recommendations referred to
MRB. Use As Is disposition require a Rejection Report Rational Form (AF021).
5.9 Customer Notification of Non-conformances and Quality Escapes
5.9.1 In the event of a Type I nonconformance being dispositioned, Use-As-
Is. a waiver must be submitted to the customer for their review. Kavlico Work
Instruction WI072 Customer Deviation and Waiver, and Kavlico Form AF118
Request for Waiver must be followed. In many cases Customers may require their
Waiver Form be used, in these cases the Customer’s Form and accompanying
Procedure shall take precedence over Kavlico’s. Most Type II nonconformance
involve lower level components and assemblies that Kavlico is the Design
Authority, unless contractually relinquished, Kavlico maintains MRB Authority
at this level. Review MRB Authority List described in WI257, which can be
found on the Intranet site. In the event a Type II Nonconformance occurs and
Kavlico does not have MRB Authority, follow the Deviation and Waiver process
identified above.
5.9.2 Completing the Request for Waiver form, AF118, shall be done by a
Quality Assurance Representative.
5.9.3 Customer approved Waivers shall be reviewed by a Quality Assurance
Representative and where special instructions are dictated by the Customer,
the QA Representative must ensure steps are taken to comply.
5.9.4 Approved Waivers must remain with the Work Order package and be filed
with the Work Order package.
5.9.5 Product where the Waiver was disapproved by the customer shall be
handled accordingly,i.e., reworked to Engineering Specification or scrapped.
5.9.6 When a Non-conformity is identified which involves product delivered to
the Customer, the cognizant MRB Quality Representative must immediately notify
the Manager of Quality.
5.9.7 Steps to contain additional product must be initiated immediately, i.e.,
Stop Order, Stock Purge, Quality Alert, etc. to ensure no additional
nonconforming product escapes.
5.9.8 An evaluation to determine the impact of the nonconformity in
relationship to the criteria defined in Type I or Type II, sections 5.7 and
5.8 respectively must take place within one working day, maybe sooner
depending on the urgency.
5.9.9 The impact and severity of the Nonconformity, as determined by the
evaluation, shall be presented to the Manager of Quality. The Quality Manager
and Cognizant Engineering
Manager shall ultimately and jointly determine the level of impact on product
and application in the field. Consideration of all Customers affected must be
taken into account.
5.9.10 When it has been determined that discrepant product has indeed been
delivered to the customer(s), Kavlico must provide a notification of escape
within 24 hours after confirming the discrepancy. In those cases, Kavlico
shall issue an internal corrective action to document the non-conformance per
AP0414 procedure. If necessary, Kavlico will request assistance from the
customer’s engineering and/or quality department in the related investigation
activities.
5.9.11 A notification of escape shall be submitted to all affected customers
in a form of an investigation report, AF338 – 8D Problem Analysis Report, or
customer required format.
The notification as a minimum shall have:
a. The affected Quantity and Serial Number Range. Note: Affected S/N Range
should be identified as close as possible, it is better to err on the side of
caution, if need be, S/N’s on either side of the suspected range should be
included to avoid having defective
product in the field. If it is discovered that the affected S/N’s needs to be
revised, the Customer must be informed and provided a revised notification of
escape.
b. The Defect must be described and its impact on the Assembly and, if
possible, the impact on the application and its intended use
c. Detail Containment measures taken to ensure no additional escapes.
d. If available at the time of the initial notification of escape, the Root
Cause and Corrective Action taken and implemented to eliminate the possibility
of recurrence must be included.
e. Disposition of Product in the Customer’s possession, i.e., return for
rework, repair, replacement, etc.
Note: At the time of the initial notification of escape not all of the
above detail may be known. Some details may need to be worked out after the
Customer assesses the impact from their end. Product may be in various
locations around the world, organizing and coordinating efforts may take some
time.
This should not delay providing an initial notification of escape to the
Customer.
CUSTOMER RETURNED PRODUCT
6.1 Customer Property that is returned to Kavlico by the Customer, or their
customer, which is identified / claimed by the Customer to be a Warranty
Return, or Quality Escape, or by Kavlico’s assessment, represents a Quality
Escape, shall be received in and then brought to the attention of the
cognizant Quality Assurance Engineer and Contracts Coordinator.
6.2 Quality Escapes or Warranty Returns must be kept separated from units
being returned to the FAA Repair Station from Customers or Air Lines.
6.3 Quality Escapes or Warranty Returns shall be addressed through the
Preventive Action System.
Note: Quality Escapes or Warranty Returns should be treated as a
notification or alert to Kavlico that a Process or System may need to be
revised. Often times a Preventive Action Request, or possibly a Corrective
Action Request needs to be issued in order to eliminate recurrence. This will
be evaluated and/or initiated by the cognizant Quality Assurance Engineer.
6.4 Processing Customer Returns shall be in accordance with WI454
6.5 Upon receiving customer notification of a Quality Escape, Kavlico shall
immediately evaluate the condition, and if required, initiate a stock purge
WI007, AF094, within 48 hours, or as required by customer.
QUALITY / MANUFACTURING ALERTS
7.1 Quality / Manufacturing Alerts may be used to highlight any internal
quality related problems concerning hardware, software, process or procedure
and to propose recommendations for correcting the problem(s).
7.2 Issuing of Quality / Manufacturing Alert shall be in accordance with WI367
and form AF148.
IDENTIFICATION AND DISPOSAL OF SCRAP MATERIALS
8.1 Material / Product determined to be scrap, shall be conspicuously
identified as scrap in some manner to preclude its unintended use. Examples of
conspicuous identification may be marked with indelible ink in a conspicuous
location; physical damage, such to render the item unusable. Scrapped products
shall be mutilated to prevent any further use within 30 days of disposition.
Note: Occasionally scrap product may be kept for machine set-up purposes,
sales examples, etc. Scrap material kept for such purposes shall be clearly
identifiable as scrap.
8.2 Scrapped material being disposed of shall be physically damaged, such to
render it permanently unusable. No efforts to rework or repair should be
possible following the physical damage.
8.3 If it is necessary to generate a certificate of scrap, Kavlico will use
form AF143-1. Quality department is responsible for the generation and control
of certificates of scrap.
QUALITY RECORDS
