The document outlines procedures for reworking seats at various Adient manufacturing locations. It defines responsibilities for applying rework standards and describes the general process. Any rework of a safety critical subsystem requires tearing down the seat and building a new one. Exceptions require approval from quality and operations leaders along with full documentation. The standard process is to identify nonconforming seats, determine if rework is possible, complete rework or teardown, test electrically, and send to shipping if passed.

4.0 Process
4.1 General: The standard for seat rework is that no item identified as safety critical (CC) in the PFMEA
or Control Plan shall be reworked without the required process controls as defined in the Control
Plan.
The standard method of rework for a safety critical (CC) seat subsystem failure is to build a new
replacement seat. The nonconforming seat must be torn down, the conforming components
returned to stock and the non-conforming parts must be placed in a clearly-marked nonconforming
material container. This is required for simplicity and minimal coordination requirements.
Rework of any seat or component must include a complete End-of-line (EoL) Electrical test and, if
required, occupant classification system confirmation.
The Plant Manager must ensure implementation and compliance with rework requirements.
4.1.1 Application: The Advanced Manufacturing Engineer / Plant Manufacturing Engineer
(AME/PltME) applies the contents of this standard and consults with the proper Subject Matter
Manufacturing Experts (SMME) for any support required when applying this standard.
4.1.2 Communication: The Regional Director of Advanced Manufacturing Engineering and the
Business Unit / Regional Manufacturing Engineering Leads ensure that the contents of this
standard are communicated to the AME/PltMEs.
4.1.3 Training: The Regional Subject Matter Manufacturing Experts (SMME) ensure that training of
the contents of this standard is provided to the AME/PltMEs.
The Certified Rework Operator must be trained to the following in accordance with the
Manufacturing Plant Employee Training and Development procedure:
 Nonconforming Material procedure
 Safety Critical Threaded Fastener Installation standard
 Rework-Seating Operations Core Manufacturing Process standard
The Operations Manager ensures:
 Training is documented, annual refresher retraining is conducted and training records are
retained by Human Resources.
 Adequate alternate operators designated and trained to support absences, vacations,
etc...

4.1.4 Exceptions: Any exceptions to these requirements must be approved by the regional Vice
President of Quality and regional Vice President of Manufacturing Operations or someone
designated in writing by these individuals, prior to implementation. Exception approval must be
retained by the Quality Manager.
Exceptions to this standard may be needed due to production constraints, such as customer
broadcast data availability, outgoing buffer deficiency, and failure rate and/or quality issues.
Exceptions are business case specific and require a full set of process documents, consisting
of: process flow, PFMEA, ODS, Control Plan and a training plan for certified rework
operators, as detailed above. Any exception must include full process documentation and
customer approval.
Examples of alternate processes may include, but are not limited to:
 Teardown of the seat to the point of failure and re-introduction to the build process
 A Kanban of sub-assemblies or seats that can re-introduced to the build process
 An offline process that duplicates all online process controls

4.2 Complete Rework Station Setup
4.2.1 The Quality Engineer or Manufacturing Engineer creates and posts the visual aids (with CC
symbols) identifying seat safety critical subsystems.
4.2.2 Rework / Teardown Criteria:
 Safety critical (CC) components may be restocked after a teardown, with the exception of
fasteners, if the component was not the reason for the teardown.
 If a safety critical (CC) process fails to achieve an OK result in the production station, the
seat must be bypassed and released to the rework area for teardown.
 All torque equipment in the rework area must only operate in reverse.
4.3 Nonconforming seat identified? The Production Operator identifies a nonconforming seat (seat fails
to achieve an OK from the standard process controls and/or appearance standards). The supervisor
/ production operator identifies the failure mode via the electronic or paper system (Bypass Log) and,
bypasses the seat from the station and routes it to the rework area.

Proprietary and Confidential AECS-MOS-ST-11-E Rev 1.0 Page 6 of 7
4.4 Failure related to CC subsystem? The Certified Rework Operator determines whether the failure is
related to a safety critical subsystem and the seat must be torn down.
4.5 CC subsystem removal required? The Certified Rework Operator determines whether the rework of
the seat requires the removal of a safety critical subsystem and the seat must be torn down.
4.6 Complete Rework: The Certified Rework Operator executes the rework or teardown process.
4.6.1 If the rework does not affect a safety critical (CC) subsystem, the seat is reworked in the
rework area.
4.6.2 Any rework or teardown of the seat must be recorded by the Certified Rework Operator in a
Rework / Teardown Log or electronic equivalent. Records must specify seat sequence
number, the defect, and final disposition (specific rework performed or teardown).
4.6.3 If the seat is torn down, the conforming components are returned to stock and the
nonconforming parts must be placed in a clearly marked nonconforming material container
and handled in accordance with the Nonconforming Material procedure. Traceability of parts
must be done in accordance with plant traceability instructions and the Material Handling,
Identification and Traceability procedure.
4.7 Complete EoL Electrical Testing: The Certified Rework Operator will execute EoL testing and
occupant classification system confirmation after any rework in accordance with the EoL Electrical
Tester Core Equipment standard.
4.8 EoL Testing Passed? The Certified Rework Operator confirms the seat passes EoL testing.
4.8.1 If the seat passes EoL testing, the Certified Rework Operator directs the seat to continue
through final inspection, bagging (if required) and labeling as specified on the ODS.
4.8.2 If the seat fails EoL testing, the Certified Rework Operator tags the part as nonconforming
material and the teardown process is initiated.
4.8.3 After Rework the Production Supervisor or Quality Engineer must verify rework completion
and sign the Rework / Teardown Log before the seat is released.
4.9 Send Seat to Shipping System
4.9.1 Last Chance Induct (LCI): The Iast designated point in the ship system that is designed to
accept seats.
4.9.2 Shipping Verification System: After all line processes and rework (if applicable) are completed,
the seat proceeds to the Shipping Verification System (SVS) where EoL testing and Serial
Data Trace information (Airbag, pre-tensioner and PODs/IEE Mat) are verified ‘good’
electronically by the system. If the system is not equipped to do this, a manual verification
must be defined in the ODS at final inspection and completed by the Final Inspection
Operator.
Note: SVS is a system, electronic or manual, that confirms all electrical testing and traceability
data for the seat at the point of shipment.
4.9.3 Verification Failure: If the SVS / manual verification indicates any failures the seat must be
thoroughly evaluated by the Final Inspection Operator to identify the failure. Once the failure
is identified and resolved, intervention / release of the seat must be authorized (via card key or
password) by a Shift Superintendent or higher level operations management.
