The purchasing decision
Create stock records with platform, drawing revision and approved substitute status. Separate unknown parts from serviceable stock. When a fleet contains several revisions, label bins by the actual service configuration rather than only by aircraft size.
Keep these records
- Platform-to-part mapping.
- Revision-specific storage labels.
- Change approval and effective date.
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.
