Level 3 PPAP checklist

Track the required elements before submission. Focus particularly on ensuring all approval signatures are obtained, dimensional results match specifications, and process capability studies show acceptable Ppk values. Rejections often occur due to incomplete documentation or missing approvals, which this checklist helps prevent.

Ensure your control plan includes all special characteristics, inspection methods, sample sizes, and reaction plans. The checklist verifies both the existence of a comprehensive control plan and its formal approval. Make sure your control plan aligns with your process flow diagram and PFMEA to maintain consistency across all documentation.

Review your customer quality manual or contract for any additional requirements beyond standard PPAP elements. The checklist includes a dedicated section to verify these unique requirements are documented and approved. Many automotive customers have specific formatting, testing, or documentation needs that must be addressed for successful submission.

Use this checklist approximately 2-4 weeks before your scheduled submission date. This timing allows sufficient opportunity to address any gaps identified during the verification process. Start collecting documentation earlier in your production planning, but perform the final verification using this checklist as you approach your submission deadline.
