8.3. Handling Extra care must be taken so that noted critical parts or areas are kept free of nicks, gouges, scratches, etc. 8.4. Traceability Critical parts shall be processed as necessary to maintain complete traceability, as specified in PS 90.1501. 8.5. Manufacturing Route Card 8.5.1. Fabricators of critical parts shall be responsible for preparing the manufacturing route card related to the fabrication of the critical part. A copy of the route card shall be submitted to IAI QA prior to processing, for review and concurrence. 8.5.2. The route card shall contain sequential fabrication, handling, processing, testing, inspection and marking steps in the correct order as required. All specifications and applicable classes shall be listed on the route card in the proper sequence. The route card shall include identification of fabricators who are to accomplish any of the processing steps. 8.5.3. Changes or revisions to an approved manufacturing route card, which alter the processing sequence or change fabricators, shall be resubmitted for review and concurrence by IAI QA prior to implementation of the change. Each revised, approved route card shall be assigned a revision letter or a revision number. 8.5.4. The route cards for critical parts shall contain steps for preserving the serial number throughout the production process (i.e. - (1) start of machining, (2) before and after operations that would remove the number, and (3) after completion of processing). 8.5.5. Acceptable "first article" examination, required by IAI Quality Assurance (IAI-QA), is mandatory prior to routine manufacturing of critical parts. 9. PROCEDURE 9.1. Inspection Procedure 9.1.1. Non-destructive Testing (NDT) Written Procedure Approval a. For metallic raw material, the procurement specification shall cover all necessary NDT requirement. b. For metallic parts, a written NDT procedure is required for critical parts. c. For composites, the NDT procedure is required only for critical parts (not for the raw materials). 9.1.1.1. In both cases the written procedure shall be submitted to IAI QA for Conditional Approval prior to testing. IAI QA shall validate the NDT procedures on-site when those procedures that require validation are part of Conditional Approval. IAI QA retains the option to waive on-site validation requirements, but procedure approval is mandatory. When validation is required, suppliers shall notify the IAI QA prior to first part inspection and the validation by IAI QA of the NDT procedure. All revisions to approved NDT written procedures shall be identified by a revision letter and shall be submitted to IAI QA for approval prior to implementation. 30 June 2000 P R O C E S S S P E C I F I C A T I O N Page 5 of 7
9.1.1.2. Complete NDT written procedures for penetrant inspection need not be submitted for each part. A general penetrant inspection procedure may be approved and supplemented with individual procedures for each part. Note: NDT personnel qualification and certification shall be per PS 81.0010. 9.1.2. First Article Inspection 9.1.2.1. After the first article of a critical part is completely manufactured in accordance with the Engineering drawing, IAI QA shall be contacted to perform the First Article Examination. 9.1.2.2. Each new supplier of critical parts, or each major change in production equipment or manufacturing practice, shall be the subject of another First Article Examination. 9.1.2.3. An Engineering drawing change that requires a new First Article Examination shall note the requirement on the change EO. 9.1.2.4. IAI QA shall conduct the examination after receipt of the request. 9.1.3. Routine Inspection of Critical Characteristics 9.1.3.1. Critical parts and critical assemblies shall be 100% inspected for surface finish to ensure that parts are free of nicks, scratches, sharp edges, sharp inside corners, etc., that are visible to the naked eye. 9.1.3.2. Where particular part characteristics are flagged with the symbol <C>, the part shall receive 100% inspection of these characteristics on 100% of the parts unless the manufacturing process is automatic (such as numerically controlled [NC] machining and NC drilling and riveting) or unless the tooling guarantees repeatability of characteristics within tolerance as specified on the Engineering drawing. 9.1.3.3. Deviation from the 100% dimensional inspection requirement because of process automation or tooling that guarantees repeatability shall require initial inspection of the tools, tool prove-out after installation and inspection of first piece manufactured and subsequently the periodic inspection of tools and sampling inspection of parts machined. These parts shall still receive a 100% visual inspection per para. 9.1.3.1 above. Note: 9.2. Material Review Periodic shall be defined as before beginning production of every batch. Material Review Board (MRB) actions for critical parts shall be approved by the relevant responsible Engineering Department. Page 6 of 7 P R O C E S S S P E C I F I C A T I O N 30 June 2000
