Quick summary

Sixteen requirements posted on Aviatrading between 18 and 26 August, listed below with part number, platform, condition and quantity. The pattern is worth a minute of any seller’s time: bearings for the A320 family dominate the list, almost everything is wanted in new condition rather than overhauled, and the ageing end of the fleet — a Boeing 707 still being supported against NSN numbers — sits in the same week as a Falcon 900EX and a Safran Arriel igniter.

What buyers asked for

Every line below is a live requirement. Condition codes follow the usual convention: FN factory new, NE new, OH overhauled.

Three things this list tells a seller

Bearings are the volume item, and they come as families. Five of the sixteen lines are bearings, four of them for the A320 in quantities of six and ten. Nobody orders a single ring roller bearing for an aircraft they intend to keep flying; these are shop-visit kits being assembled ahead of time. A seller holding one number from that family and not the rest will lose the enquiry to whoever can quote the set. If you stock bearings, publish the family, not the item.

Fifteen of the sixteen lines want new material. Thirteen are marked new and two factory new; exactly one, the Falcon 900EX brake assembly, is specified as overhauled. That runs against the assumption that price-sensitive markets automatically reach for used serviceable material. For small consumable rotables — bearings, diodes, brushes, an igniter — the certification paperwork on a used unit costs more attention than the part is worth, and buyers would rather pay for a clean new item with a straightforward release. USM demand concentrates further up the value scale, on the assemblies where the price gap is large enough to justify the documentation work.

The old fleet is still being fed. Two lines are Boeing 707 items quoted against NSN numbers — a limit switch and a rudder trim chain assembly, one of each, both factory new. An aircraft type that left production decades ago is still generating single-unit requirements, and the NSN reference points at a government or military supply channel rather than a commercial catalogue. Alongside it in the same week sit a Falcon 900EX and a Safran Arriel igniter in a quantity of six. Three very different worlds, one week, one marketplace.

What it means if you are buying

Two practical notes for anyone sourcing against this kind of list. First, quantity is a negotiating asset: a request for six of one bearing part number attracts better pricing than six separate single-unit requests, and it tells the seller you are building a kit rather than chasing one AOG item. Second, state the condition you will actually accept. Half the wasted cycles in parts procurement come from a buyer writing “new or overhauled” and then rejecting the overhauled offer because the release paperwork was not what they had in mind — a problem we covered in detail for operators without their own CAMO.

If your fleet sits on the ageing end — the turboprops and early jets that still carry most regional traffic in Africa and South Asia — the same discipline applies with more force, because the supply base is thinner and a rejected offer may not be replaced quickly. We have written separately about ATR and Dash 8 support in East Africa and about routing parts through Nairobi and Addis, both of which start from the same constraint.

How this list is put together

Everything above comes from requirements posted publicly on Aviatrading during the period stated. We publish part number, item description, platform, condition code and quantity, and nothing else. Buyer names, companies and contact details never appear in these reviews — if you want to reach a buyer, you do it through the platform, by quoting against their requirement.

The aggregate observations above are drawn only from the sixteen lines in the table. Where we say bearings dominate, we mean five of these sixteen; where we say new condition dominates, we mean fifteen of these sixteen.

This replaces the weekly format we used for our first digest. Requirements do not arrive evenly across a calendar week, and a fixed weekly slot produced either a thin table or a wait. From now on a review goes out when there is enough on the board to be worth reading — in practice every week or two.

Quote against these requirements

Every part number in the table links to the live requirement. If you hold the item, or can source it, register as a seller on Aviatrading and quote directly — every transaction on the platform is protected by escrow, so payment moves only when the deal closes. If you are on the buying side and your requirement is not on this list, post it as an RFQ and let verified sellers come to you. New requirements appear continuously on our Telegram channel.
