Key Takeaways
- An aerospace machining inspection documentation package is a structured record set that proves a machined component meets every drawing, material and process requirement before shipment.
- AS9102 organizes First Article Inspection evidence across three forms: Form 1 for part-number accountability, Form 2 for raw-material and sub-component traceability and Form 3 for characteristic accountability with measured values.
- Complete traceability relies on a documented four-link chain that connects the material test report, process certifications, dimensional report and certificate of conformance that references the heat or lot number.
- A six-stage workflow that includes ballooned drawing creation, in-process data collection, FAI versus production differentiation, digital packet assembly, portal upload and change-control linkage supports audit-ready submissions that satisfy AS9100D and AS9102.
- Precision Advanced Manufacturing delivers complete, audit-ready aerospace inspection packages; start a program with built-in documentation from the first part.
AS9102 Forms and Part-Number Accountability
AS9102 organizes FAI evidence across three forms, and each form covers a distinct accountability layer. All three forms must be present for a complete submission.
Form 1 establishes the design baseline and records the reason for the FAI. Form 2 links every raw material and purchased sub-component to a supplier certificate of conformance. Form 3 records each ballooned characteristic with the actual measured value and the calibrated equipment used to obtain it. A submission missing any one form is incomplete under AS9102 and will be rejected at the customer quality portal. Form 2 and the CoC both depend on a documented traceability chain that connects raw material to the finished part.
Heat-Lot Traceability and the Certificate of Conformance
Traceability is the documented chain that connects a specific heat or lot of raw material to the finished part and its CoC. Aerospace customers expect to see a four-link chain that includes the material test report, process certifications, dimensional report and certificate of conformance.
The CoC must explicitly reference the heat or lot number from the MTR to complete the traceability chain. Without that explicit reference, the chain breaks and the customer cannot verify that the material in the finished part matches the certified test report, which triggers a rejection or a corrective action request.
Precision Advanced Manufacturing operates under AS9100D and ISO 9001:2015 certified quality management systems with ITAR registration, so traceability linkage is built into every production traveler from material receipt through final inspection.

Six-Stage Workflow for Assembling the Inspection Package
This six-stage workflow structures inspection data from the first ballooned drawing through portal upload so every package aligns with AS9100D and AS9102 requirements.
Stage 1: Ballooned Drawing Creation From Customer Model
The ballooned drawing serves as the master reference document. Each dimension, tolerance, note and callout on the engineering drawing receives a sequential balloon number. Those numbers become the index for Form 3 characteristic entries. Balloon numbers must match exactly between the drawing and the inspection report, because any mismatch causes a cross-reference failure during audit. Precision Advanced Manufacturing generates ballooned drawings directly from customer-supplied CAD datasets, which preserves revision-level integrity from the start.
Stage 2: In-Process Data Collection Points
In-process data collection captures characteristics that cannot be measured on the finished part because later operations obscure or alter them. Critical features such as pre-plate dimensions, weld joint geometry or heat-treat condition must be recorded at the process step where they are accessible. In-process inspection records are dated, signed and tied to the production traveler so they appear as supporting evidence in the final package rather than as undocumented assumptions.
Stage 3: First-Article Versus Production Inspection Differentiation
A First Article Inspection covers 100 percent of drawing characteristics on the first conforming part. Subsequent production inspection plans are risk based and may sample a defined subset of characteristics. The FAI package must clearly identify which inspection type applies. Mixing FAI records with production sampling records in a single submission is a common rejection trigger. Each record set carries its own cover sheet that identifies the inspection type, part serial number and applicable work order.
Stage 4: Digital Packet Assembly and Naming Conventions
Digital packet assembly creates a single, organized submission for the customer quality portal. Customer quality portals typically require a single compressed archive or a structured folder upload. A consistent file-naming convention prevents version confusion and speeds portal processing.
A practical convention follows this pattern: PartNumber_RevLevel_DocumentType_Date. For example: 12345A_RevC_Form3_20260624. Every file in the packet uses the same part number and revision prefix so portal software can index the submission. PDFs serve as the standard format, and native CMM output files appear as supplemental attachments, not replacements for the signed PDF report.
Stage 5: Quality-Portal Upload and Acknowledgment
Quality-portal upload transfers the complete packet to the customer system in a single, traceable step. Most prime contractors and Tier 1 customers use supplier quality portals such as Exostar, SupplierGateway or proprietary systems. Upload the complete packet as a single submission rather than separate files.
After upload, confirm that the portal has generated an acknowledgment or submission number. Retain that acknowledgment in the internal quality record. If the portal returns an automated rejection for missing documents, address each line item before resubmitting. Partial resubmissions that leave gaps unresolved extend review cycles.
Stage 6: Change-Control Linkage for Revision-Level Traceability
Change-control linkage connects each production lot to the drawing revision that governed its manufacture. When a drawing revision is released after an approved FAI, the supplier must determine whether the change affects form, fit or function. If it does, a partial or full delta FAI is required.
The new FAI package references the previous approved FAI number and documents only the characteristics affected by the change. Revision-level traceability, which records the drawing revision that governed each production lot, is a mandatory AS9100D requirement and a frequent audit finding when it is absent. The following checklist consolidates the documents referenced throughout the six-stage workflow into a single verification list.
Audit-Readiness Checklist: Eight Required Documents
The following eight documents constitute a complete aerospace machining inspection documentation package and serve as the final verification step before portal upload. Use this checklist to verify completeness before portal submission.
- AS9102 Form 1 – Part-number accountability with FAI reason code and design index
- AS9102 Form 2 – Raw-material and sub-component accountability with CoC references
- AS9102 Form 3 – Characteristic accountability with ballooned drawing, actuals and equipment IDs
- Ballooned Drawing – Customer-approved revision with sequential balloon numbers that match Form 3
- Material Test Report (MTR) – Mill-certified chemistry and mechanical properties tied to heat or lot number
- Special Process Certifications – Heat treat, plating, anodize, NDT or other applicable process records
- Calibration Records – Current calibration certificates for every measurement instrument referenced in Form 3
- Certificate of Conformance (CoC) – Signed statement that references part number, revision, heat or lot and applicable specifications
Red-flag language to avoid on a CoC: “Inspected to best commercial practice,” “material per customer specification” without a specification number or any statement that omits the drawing revision level. These phrases signal nonconformance to AS9100D auditors and generate immediate corrective action requests.
Start with audit-ready documentation aligned to AS9100D and AS9102 requirements from the first submission.
Common Documentation Challenges and Practical Fixes
Traceability gaps between MTR and CoC. This gap occurs when a material is split across multiple work orders and only one work order number appears on the CoC. The fix is a material split record that documents each sub-lot, its originating heat number and the work order it was assigned to.
Missing calibration linkage. Form 3 requires the equipment ID for every measurement. If the calibration certificate for that equipment ID is not included in the packet, the measurement result is unverifiable. A calibration register that maps every instrument ID to its current certificate and expiration date keeps this linkage clear, and the relevant certificates appear as a dedicated section of the packet.
Late design-change documentation. Engineering changes issued after production begins sometimes reach the shop floor after parts are already inspected. When this happens, the inspection record references the superseded revision. The corrective action is a documented concession or reinspection against the new revision, with a clear record that shows which revision governed the shipped lot. Precision Advanced Manufacturing uses a change-control process that flags revision updates at the traveler level, which prevents uninspected design changes from reaching the shipping dock.
Frequently Asked Questions About AS9100D, AS9102 and FAI
What is the difference between a full FAI and a delta FAI?
A full FAI covers every characteristic on the drawing and is required for new parts, new suppliers or major design changes. A delta FAI covers only the characteristics affected by a specific engineering change order. The delta FAI package references the previously approved full FAI by its approval number and documents only the changed characteristics with new measurements and updated forms.
How does AS9100D relate to AS9102?
AS9100D is the quality management system standard that governs the entire aerospace manufacturing operation, including processes, risk management, configuration control and continual improvement. AS9102 is a specific procedural standard that defines how to conduct and document a First Article Inspection. AS9100D requires that FAI be performed, and AS9102 defines exactly how to do it. A supplier can hold AS9100D certification without a contractual requirement to follow AS9102, but most aerospace prime contracts invoke AS9102 by reference.
What triggers a requirement for a new FAI on an existing part?
Common triggers include a drawing revision that affects form, fit or function, a change in raw material source or specification, a change in manufacturing process or facility, a lapse in production beyond the period defined in the customer purchase order and a change in sub-tier supplier for a critical sub-component. Each trigger type is documented in the FAI reason code field on Form 1.
How are digital quality packets managed when a customer portal is not available?
When a customer does not operate a supplier portal, the documentation package is transmitted as a structured email attachment or a shared secure folder link. The same file-naming conventions apply. The supplier retains a timestamped transmission record, such as an email send confirmation or folder access log, as evidence that the package was delivered before or concurrent with the shipment.
What role does ITAR registration play in documentation handling?
ITAR registration governs the export control of defense-related technical data, which includes drawings, specifications and inspection records for controlled parts. An ITAR-registered supplier such as Precision Advanced Manufacturing maintains access controls on all technical documentation, restricts transmission to authorized U.S. persons and licensed foreign nationals and retains records in compliance with ITAR recordkeeping requirements. This approach protects both the supplier and the customer from export control violations during documentation exchange.
