The purchasing decision
Record aircraft, subsystem and part revisions with position photographs. Request an exploded-view reference or controlled drawing when available. Separate a genuine replacement request from a proposed alternative so the service team can review it properly.
Keep these records
- Aircraft and subsystem identity.
- Part number and position.
- Approved replacement scope.
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.
