General Notes

  1. Depending on the number of characteristics, multiple sheet may be needed. In such case, identify and fill in “Sheet _ of _”

1. Part Number


Please refer to 1. Part Number of Form 1.

2. Part Name


Please refer to 2. Part Name of Form 1.

3. Serial Number

Conditionally Required

Please refer to 3. Serial Number of Form 1.

4. FAIR Number

Conditionally Required

Please refer to 4. FAIR Number of Form 1.

5. Char. No.


This is the assigned number for each feature/characteristic. I have created a detailed instruction on how to assign numbers. Please read at Numbering drawing.

The Char. No will be plain numbers, or numbers followed by -1, -2 if one call out includes more than one characteristic.

Different customers have different requirements about basic dimensions and reference dimensions. As best practice, it is suggested to assign numbers to these dimensions.

6. Reference Location

Conditionally Required

For single part, reference location is usually the drawing zone, and page number/section if the drawing has more than one page. For assemblies, this can be line/page number of a BOM.

Below is an example showing drawing zones of a single part. For example, the chamfer callout's reference location is F7. Drawing from Taomaker LLC, used under CC-BY-SA License.

7. Characteristic Designator

Conditionally Required

Sometimes, certain characteristic will have special designators, such as:

  • Critical/key feature
  • Critical item
  • Vehicle safety related

These are defined by AS9100 Clause 3.3 and 3.4.

If there are such designators, put them in this column. Otherwise, use “N/A”.

8. Requirement


This is drawing callout, drawing notes, specification requirements etc.

  • Use same unit specified in drawing
  • Default/unspecified tolerance: as a best practice, add these tolerances to this cell.

9. Results

This is for measurement result. The results can be in one of below forms:

  1. Numbers If the result is numerical values.
  2. Pass/Fail If inspection is done using Go/Nogo gages, or if the requirement is a functional test.
  3. Accept If the requirement needs verification per design characteristics, such as “no burrs allowed per internal standard xxxx” or attribute inspection, such as “All dimensions apply after anodize”.

For basic dimensions, put “Basic Dimension” here.

For reference dimensions, put “Reference Dimension” here, add note in Column 14 the referred sources.

Automated Inspection

When you use CMM or other automated inspection equipment, usually an inspection report will be attached. We need to make sure

  • Char. No (Column #5) is clearly linked in the attached report. For example, you can put in Column #14 “CMM Report LOC6 - CIR12”.
  • The attached report shall have a unique report number.
  • The attached report shall specify the Char. Numbers measured.

10. Designed/Qualified Tooling

Conditionally Required

When designed tooling, such as specific jig, or CMM program is used, record the tooling identification number.

When standard gages, such as pin gages, ring gages, thread gages etc are used, put gage name and value here.

For visual inspection, use “VISUAL”.

11. Nonconformance Number

Conditionally Required

If this line is found to be nonconforming, record an NC number here. It can be a sequential number specially for this FAIR, such as “NC-1”, “NC-2”, or a reference number pointing to another nonconformance record.

12. Signature


Same to Form 1 Cell 19.

13. Date


Date when Cell 12 is signed.

14. Additional Data/Comments
