# Writing a SCAR

## When to issue

| Issue a SCAR | Handle without a SCAR |
|--------------|-----------------------|
| Nonconforming product that reached production or the customer | One-off minor defect caught at receiving with no impact (record, trend) |
| Repeat nonconformity (same part and defect) | Paperwork error corrected immediately |
| Safety, regulatory or special-characteristic defect | |
| Scorecard grade D or PPM above target without action | |
| Late deliveries causing line stops or premium freight | |
| Audit finding at the supplier | |

## Content of the request

| Section | Content |
|---------|---------|
| Identification | SCAR number, supplier, part number and revision, PO, lot / heat, NCR reference |
| Problem | Requirement (spec, revision) vs actual (measured), quantity affected and inspected, where found, evidence (photos, reports, samples returned) |
| Impact | Line stop, sorting, customer complaint, cost to be recovered |
| Required response | Containment in 24-48 h (including stock at supplier, in transit, at our site and at our customer; clean point), root cause and actions in 10 working days (8D format if required), closure with effectiveness in 30-60 days |
| Contacts | Supplier quality engineer, how to submit |

## Example problem statement

> Requirement: no porosity larger than 0.5 mm on machined faces (spec CS-14 rev B, drawing CA-77 rev D note 4).
> Actual: pores 0.8-1.5 mm on face B on 8 of 150 parts from lot L2609-03, found at machining OP20 on 2026-09-11.
> Evidence: NCR-2608 with photos and a sectioned sample (sent 2026-09-12). Impact: 8 parts scrapped after machining;
> remaining stock on hold.

## Cost recovery

State the recoverable costs in the SCAR or the supplier agreement: sorting labour, scrap of added value, line
downtime, premium freight, customer charge-backs. Recover them consistently; it is part of the business case for
the supplier to fix the cause.
