The purchasing decision
Request the exact compatible part references and assembly instructions. Check the intended envelope using the builder’s procedure. Treat cracked, distorted or unidentified returns separately from new serviceable stock.
Keep these records
- Matched component references.
- Clearance review.
- Condition and replacement criteria.
Give each record an owner and a revision or date. If a supplier proposes a different part or test condition, record it as an exception for review before treating the quotation as equivalent.
Turn the review into a sourcing request
Start with the linked component checklist, add the actual platform and part identity, and state quantity, destination and timing. List unresolved requirements explicitly so the first discussion can focus on those gaps.
