What is in this review
This is the fourth review of open requests posted on the Aviatrading marketplace. It covers the requests logged between 17 September and 1 October 2026 that were still open when the table below was compiled. Eleven are listed. Each line is a real request from a verified buyer, and every link goes to the live request page where you can quote it.
We publish buyer-side detail only: the part number or item, the category, the platform where the buyer stated one, the condition codes the buyer will accept, and the quantity. Names of buyers and buying companies are never published, here or anywhere else on this site. If you hold the part, you quote through the platform and the buyer sees your offer — not the other way round.

Reading the table
Five of the eleven lines are landing gear, and four of those five belong to one ATR 42/72 package: both main landing gear assemblies and both side braces, left and right, posted together. That is a recognisable shape. A buyer who posts matched left and right assemblies alongside their side braces is not topping up a shelf; they are rebuilding a gear position or preparing a heavy check, and they will almost certainly place the whole package with whoever can cover the most of it. If you hold two of those four, say so in one quote rather than four, and say what you cannot cover. The same logic applies to the Legacy 650 nose gear door, which is a single line but sits in the same chapter.
The two engine lines are the opposite case. A GE90-115B and a CFM56-5B4/3 are single, high-value items where the records decide the transaction, not the price line. Both buyers will accept overhauled or serviceable units, which tells you the shop paperwork and the life status of any limited-life hardware inside will be examined before anything else. If you are quoting either, lead with what documentation travels with the unit. Our note on back-to-birth records on engine modules sets out what a buyer in that position is normally asked to produce, and airworthiness directive and service bulletin status covers the second question that follows immediately.
Two lines are worth reading for their condition fields rather than their part numbers. The GBE board accepts eight different condition codes and the extinguisher accepts six, which in practice means the buyer is open to almost anything that comes with an acceptable release document. A wide condition field is an invitation to quote, not a sign of indifference — but it also means the quotes that arrive will be hard to compare, and the one that wins will usually be the one that states its condition and its paperwork most plainly. We wrote about exactly that problem in why the same part number comes back at three different prices. Note also that the extinguisher is a line where dangerous goods handling will shape the delivered cost, and a quote that ignores it will be re-opened later.
Two quantity outliers close the list: the electromagnet at ten units and MS91528-0E1B at one hundred. On a marketplace where most lines are a single unit, a three-figure quantity is a stock buy rather than a repair, and it rewards a seller who can confirm a single batch and a single release document instead of an assembly of odd lots.
One request from this period has been left out of the table deliberately. It is a military rotorcraft item, and we do not list military positions in these reviews. That is an editorial rule on this site, not a comment on the request.
How to quote one of these
Every line above links to its own request page, where the full specification and the buyer’s stated requirements sit alongside the quote form. Quoting is free and does not require a subscription or a listing fee; payment on a closed deal is protected by escrow on both sides. If you hold inventory against any of these, the useful move is to quote the line you can actually ship, state the condition and the release document in the first message, and name your lead time — those three facts decide most of these transactions before price is discussed at all.
If none of them matches your stock, the open requests change constantly. You can browse every live request, register as a supplier to be notified when a request matches what you hold, or follow new requests and listings as they are posted on the Aviatrading channel on Telegram. For sellers working from teardown and surplus stock, our guide to traceability on used serviceable material is the one worth reading before you quote a landing gear rfq of this kind.
