Change & Second-Source Qualification

Use for obsolescence replacements, second sources and manufacturing changes. A risk-based plan helps avoid unnecessary full requalification while addressing changes that could affect reliability.

The scope is tailored to the available evidence. Useful inputs include:

• Baseline design and proposed change
• Existing qualification and field evidence
• Material, process, supplier and specification differences

SPACEREL compares the proposed change with the qualified baseline and identifies affected mechanisms and interfaces. A proportionate analysis and test programme is developed, with traceability to the change risks and customer acceptance requirements.

Deliverables are agreed before work starts and can include:

• Change impact and evidence-gap assessment
• Targeted qualification plan
• Release recommendations based on available evidence
