Buyer guide
A practical guide for aircraft parts buyers, MRO and repair teams, brokers, and procurement teams. Six tips that turn a noisy request into a clean RFQ — plus the pitfalls that cost most buyers a week of back-and-forth.
Tips
Part number, NSN, NIIN, or CAGE — whichever is most specific. Identifier-led RFQs reduce ambiguity and surface alternates faster than free-text descriptions.
New, overhauled, serviceable, repaired, as-removed, exchange, or surplus. Operator quality systems treat each condition differently — leaving it implicit costs days.
FAA 8130-3, EASA Form 1, CoC, ATA 106, mill cert, dual release, tag. PartsPerk asks suppliers to confirm document availability before the quote moves forward.
AOG, today, this week, standard, research-only. Marking everything urgent dilutes the AOG escalation; marking nothing urgent loses the AOG channel when you need it.
Aircraft platform, ATA chapter, removed-from-service notes, or a photo. Discovery flow narrows down the family before the RFQ goes out — buyer effort up front saves supplier rounds later.
Receiving inspection should not be a renegotiation. Confirm the document plan, condition, and any deviations against the operator quality system before the PO is cut.
Pitfalls
Suppliers reply with whatever they have. New-vs-overhauled prices and lead times can vary by 5–10×. Specify condition or accept that the supplier picks for you.
If your repair station requires 8130-3, say so. PartsPerk asks suppliers to confirm before quote moves forward — you avoid a week-long back-and-forth on paperwork.
Tagging non-grounded requests as AOG erodes the urgency channel. Use 'today' or 'this week' for time-sensitive requests; reserve AOG for actual grounded aircraft.
If you accept alternates / PMA, say so. If you do not, say that. Alternates surfaced unilaterally without operator approval are a quality issue, not a sourcing win.
RFQ checklist
A clear request gets a clear quote. Add these fields when you send a request — most fields are optional but the more you provide, the faster the right aviation parts source can reply.
Documents
Buyers should review supplier-provided documents, condition, eligibility, and compliance requirements before any purchase. PartsPerk does not certify airworthiness — the supplier provides paperwork; you review.
FAQ
Lead with the identifier (part number or NSN), specify quantity + condition, add the document set, and submit. Most buyers send a clean RFQ in under 60 seconds when they have the identifier in hand.
Suppliers are matched on capability, FSC, OEM relationship, and document depth. Backup suppliers queue behind the primary so a no-bid does not stall the line. The buyer never sees supplier identity until a quote returns.
Yes. Each RFQ is its own thread with its own document plan. Procurement teams can share RFQ visibility, route requests to specific buyers, and keep one source of truth across the team.
PartsPerk asks suppliers for condition, lead time, and document set on every line. Incomplete replies are flagged so the buyer can request the missing fields without rebuilding the RFQ.
No. PartsPerk does not certify airworthiness. The repair station that issues the 8130-3 / EASA Form 1 carries that responsibility; the buyer reviews the documents and condition before install.
Buyer email and contact details are not shared with non-replying suppliers. PartsPerk publishes its data and security posture at /trust and a buyer can request data deletion at any time.
Send your next RFQ with a part number, condition, document set, and needed date. PartsPerk routes; you review documents before order.
