Limitations and/or modifications to the Approval are noted by a limitation code (use "Limitation Code Index") or a notation following the Process Code approval. An asterisk (*) next to the company name denotes all approvals are for "Internal Support Only."
CERTIFICATE OF CONFORMITY: A document issued by the supplier to confirm that the delivered products fulfill the relevant specification, applicable design data (e.g. drawing) and purchase order requirements.
DELIVERABLE - Production hardware that is intended for final installation on a Boeing product.
DESIGNATED FASTENER - For the purpose of this document, designated fasteners are defined as those bolt, nut, collar and rivet D-590 standard part numbers that require manufacturing, testing and certification to the Boeing Part Specifications (BPS).
DISAPPROVED - Status given a supplier’s quality system, Processor/Supplier and/or process code approval that has been removed due to major non-conformance(s) or unresponsive corrective action.

CHANGE OF APPROVAL STATUS |
| |
|
The approval status of Processors, as established by this document, shall be changed only by a Boeing SQ Field Representative and effective upon notification to the processor for the following categories and may be partial by process code number or complete by Processor. |
| |
11.1. |
Probation Status: This category is a temporary suspension of the Processor/Supplier approval and requires immediate attention and completion of all required phases of survey action and/or corrective action. Processing on Boeing hardware or supplying materials per the affected approvals shall not occur during the Probation period without appropriate oversight as directed by The Boeing Company.
The unauthorized processing of product to specifications under Probation status is grounds for disapproval of all D1-4426 processes. Authorization to process parts during probation shall be the responsibility of the assigned Process Representative.
Processor/Supplier's Approval/s will be removed from D1-4426 during the Probation period (for individual process code approval or for all approvals).
Probation status may be assigned to a processor/supplier for, but not limited to, the following reasons: |
| |
|
11.1.1. |
Inability to pass or failure to submit test panels for qualification/verification testing. Required test panels are to be provided by the Processor/Supplier. |
| |
|
11.1.2. |
A nonconformance that is systemic and indicates a severe process or sub-process breakdown, which may impact the Processor/Supplier’s ability to meet customer quality system requirements, or may result in significant hardware nonconformance (Major Nonconformity)." |
| |
|
11.1.3. |
Failure to submit acceptable corrective action within the time period established on the Supplier Evaluation Report (SER). |
| |
|
|
11.1.3.1. |
Processor/Supplier has 20 manufacturing days from the date of SER notification. The 20 manufacturing days is the accumulation of all days utilized by the processor/supplier for all cycles of corrective action with the assigned Process Representative. It is recommended the processor/supplier submit the initial corrective action within 10 manufacturing days to allow for additional cycles of responses. |
| |
|
|
11.1.3.2. |
Processor/Supplier is considered non-responsive if the total days accumulated by the processor/supplier exceeds 40 manufacturing days. Probation may be issued by the assigned Process Representative if the corrective action is not proceeding to satisfactory completion. |
| |
|
|
11.1.3.3. |
The assigned Process Representative will return unsatisfactory corrective action to the supplier/processor for an additional cycle of corrective action. Probation may be issued when the supplier/processor fails to provide adequate corrective action within four cycles (initial submittal plus three additional cycles). |
| |
|
|
11.1.3.4. |
Failure to submit acceptable corrective action (non-responsive or multiple cycles of corrective action) may be cause for a Major finding against the Supplier's/Processor's quality management system (QMS). |
| |
|
11.1.4. |
Failure to implement corrective action as planned to correct a known deficiency (i.e. non-sustaining corrective action). |
| |
11.2. |
Disapproved Status:
This category will result in the removal of a portion of or all of a Processor/Supplier Approval to perform processes and/or manufacture materials in accordance with D1-4426. Processing or supplying of material shall not occur while a processor is Disapproved unless source accepted by an authorized Boeing representative. In addition, a Disapproved Processor cannot accept new contracts for Boeing hardware. Processor's status will be altered in D1-4426 to reflect the change in status. A full Processor/Supplier disapproval will result in the removal of the Processor from D1-4426.
Processor/Suppliers Disapproved will not be considered for reapproval for a period of five (5) years from the date of disapproval unless the Supplier Quality senior management agrees to a reduced period.
Disapproved status may be assigned for, but not limited to, one of the following reasons:
|
| |
|
11.2.1. |
Failure to adequately address and implement corrective actions while on Probation. |
| |
|
11.2.2. |
Activities that are perceived to be deliberate affecting the quality of the hardware. |
| |
|
11.2.3. |
Gross negligence affecting the quality of the hardware. |
| |
11.3. |
Withdrawn Status: This category is provided for the removal of a Processor's Approval for reasons other than disapproval. Withdrawal will result in the removal of one or more processes from the processor’s D1-4426 approvals. Processors whose approval has been Withdrawn are still eligible for possible reinstatement provided there is a justified need.
Withdrawn status may be considered for, but not limited to, one of the following reasons: |
| |
|
11.3.1. |
No processing since the last Boeing maintenance activity. Consideration shall be made for long term contract procurements/deliveries and spares procurement. |
| |
|
11.3.2. |
A request by the Processor/Supplier to be removed from D1-4426. |
| |
|
11.3.3. |
Removal of equipment, personnel or facilities required to perform approved process(es). |
| |
|
11.3.4. |
Relocation of facility or change of ownership. |
