The purchasing decision
Use the manufacturer’s nomenclature and documentation for the exact item. Preserve the viewing convention for CW/CCW and include the hub or adapter. Keep proposed substitutes separate until the responsible builder approves the complete pairing.
Keep these records
- Exact propeller reference.
- Rotation and hub interface.
- Maker’s installation and limit documents.
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.
