# First Article Inspection Checklist

Use this checklist to plan first article inspection for SMC axial flux cores, AFPM stators, segmented teeth, tooling samples, or related motor-core components.

This file is a planning template. It is not a released inspection report.

## 1. Program Identification

- Buyer:
- Project:
- Part name:
- Part number:
- Drawing revision:
- Sample ID:
- Supplier lot ID:
- Inspection date:
- Inspector:

## 2. Drawing and Datum Control

- Latest 2D drawing received:
- STEP or DXF file received:
- Datum scheme confirmed:
- Ballooned drawing required:
- CTQ dimensions identified:
- Tolerance stack reviewed:
- Drawing notes and finish requirements reviewed:

## 3. Measurement Plan

| Characteristic | Drawing Requirement | Method | Sample Result | Status |
| --- | --- | --- | --- | --- |
| OD |  |  |  | pass / review |
| ID |  |  |  | pass / review |
| Axial height |  |  |  | pass / review |
| Tooth or segment pitch |  |  |  | pass / review |
| Air-gap face flatness |  |  |  | pass / review |
| Mounting datum |  |  |  | pass / review |
| Critical slot or tooth detail |  |  |  | pass / review |

## 4. Material and Process Checks

- Material lot recorded:
- Density or weight checked:
- Thermal process route recorded:
- Machining allowance confirmed:
- Coating or insulation status checked:
- Visual defects reviewed:
- Handling damage reviewed:

## 5. Buyer Review

- Deviations listed:
- Engineering concessions needed:
- Corrective action needed:
- Accepted for magnetic validation:
- Accepted for assembly trial:
- Accepted for pilot quote:
- Re-sample required:

## 6. Release Boundary

All accepted results should reference drawing revision, sample ID, measurement method, and reviewer decision. Do not reuse a first article result for a different drawing revision or process route without review.

## Example Acceptance Language

Each CTQ result should identify drawing revision, sample ID, inspection method, measured value, tolerance, and release status before pilot build approval.
