Planning
Defines when a first article is required, what it must cover, who performs it, and who approves it.
First Article Inspection Guide
First article inspection verifies the manufacturing result before full production.
A first article inspection compares an initial production item and its records with the drawing, specifications, material requirements, processes, and customer expectations.
Overview
Build quality into the manufacturing system.
First article inspection is more than checking a few dimensions on a prototype. A complete first article should represent the intended production method, tooling, material, equipment, processing sequence, inspection approach, and supplier location. Its purpose is to identify misunderstandings and process gaps before they affect a larger production quantity.
Core Concepts
The controls, evidence, and decisions that support reliable output.
These categories organize the topic around practical manufacturing, inspection, supplier, and quality-system responsibilities.
Production Representation
Uses the intended equipment, tooling, material, routing, operators, and outside processes whenever required.
Drawing Accountability
Accounts for dimensions, geometric tolerances, notes, specifications, finishes, and referenced requirements.
Material Verification
Confirms grade, condition, heat or lot, certification, approved sources, and applicable test reports.
Dimensional Inspection
Records actual results using suitable gauges, fixtures, CMMs, optical systems, or laboratory methods.
Special Processes
Verifies plating, coating, heat treatment, welding, cleaning, testing, and approved processing sources.
Nonconformance
Identifies failed characteristics, containment, disposition, correction, reinspection, and approval status.
Change Triggers
Defines when design, tooling, process, location, equipment, lapse, or supplier changes require a new or partial first article.
When a first article is required
A first article is commonly requested for a new part, a new supplier, a new tool, a significant engineering change, a process transfer, or a long interruption in production. Customer, industry, or contract requirements may define specific triggers.
A partial first article may be appropriate when a change affects only certain characteristics. The affected features, related operations, and supporting records should still be clearly identified.
Why a prototype is not always a first article
A prototype may be produced using temporary tooling, substitute material, manual finishing, additive manufacturing, or a different supplier. It can prove function without proving that the final production process is capable of meeting every requirement.
A first article should normally come from the intended production route. When deviations are necessary, they should be documented so reviewers understand what has and has not been validated.
What the inspection package should contain
The package may include a ballooned drawing, characteristic list, actual measured results, material certificates, special-process certificates, functional test results, gauge information, approved deviations, and identification linking the report to the inspected item.
Results should be reported as actual values when practical rather than simple pass/fail statements. This makes it easier to identify borderline conditions and evaluate whether the process has sufficient margin.
How first article approval supports production launch
Approval confirms that the defined configuration was reviewed and that the submitted evidence demonstrates conformity. It does not replace ongoing inspection or process control.
After approval, the manufacturer must preserve the controlled process and manage changes. Production monitoring, capability analysis, calibration, preventive maintenance, and traceability continue to protect the approved result.
Implementation Checklist
What manufacturers and buyers should verify.
Use these areas to review system readiness, supplier evidence, production controls, and quality records.
Ballooned Drawing
Assign a unique characteristic number to each dimension, note, feature, and applicable requirement.
Actual Results
Record measured values, test results, acceptance criteria, inspection method, and completion status.
Material Records
Include grade, condition, heat or lot identification, certificates, and required laboratory reports.
Process Certificates
Provide evidence for heat treatment, plating, coating, welding, passivation, cleaning, or testing.
Part Identification
Link the inspected item to the report, drawing revision, production order, tool, lot, and supplier.
Approval Status
Document acceptance, conditional approval, rejection, required correction, and resubmission activity.

First Article Inspection Guide FAQ
Is a first article inspection the same as a prototype inspection?
Not necessarily. A prototype may use temporary methods or substitute materials. A first article normally verifies output from the intended production configuration.
Does first article approval eliminate future inspection?
No. It approves the submitted configuration and evidence. Ongoing process control, inspection, calibration, traceability, and change management are still required.
What changes can require a new first article?
Common triggers include design revisions, new tooling, significant tool repair, process changes, equipment changes, supplier transfers, location changes, and long production interruptions.
