AS9120 Training for Distributors: What Stockists Need That Manufacturers Don't

A distributor sending its quality team on an AS9100 course is making a reasonable mistake. The standards look similar, the clause structure is familiar, and the course is easy to book. But a manufacturer's course spends its time on design, production control, special processes and first article inspection — and a stockist does none of those things.

What a distributor actually does is take custody of somebody else's product and keep the evidence of what it is intact. In AS9120, the paperwork is not supporting the product. In a real sense, it is the product.

Train for that, and the course becomes useful.

Where AS9120 genuinely differs

Five areas carry nearly all the audit risk for a distributor, and all five need explicit training.

Traceability and chain of custody. Every item needs an unbroken documented line back to the manufacturer, through every pair of hands it has passed. Training should cover what an acceptable trace looks like, what to do when a trace is incomplete, and why "we have always bought from them" is not a trace. Your people need to be able to look at an incoming package of certification and say what is missing.

Counterfeit and suspect unapproved parts. This is the single biggest exposure in distribution and it deserves more than a slide. Training should cover approved source control, the risk profile of open-market and broker purchases, what visual and documentary inspection can and cannot detect, what triggers escalation, and the obligation to quarantine and report rather than return suspect material into the supply chain. People need to know they will be supported for stopping a shipment, not blamed for the delay.

Splitting, re-identification and preservation of identity. When a batch is split, the identity and traceability have to survive the split. This is where small distributors most often fail an audit — not because they do not understand the principle, but because the practical controls at the bench have never been trained. Who applies the new label, who verifies it, what record is made, how the remaining quantity is reconciled.

Records and retention. Certificates of conformity, test reports, material certifications, airworthiness release documentation where applicable. What has to be kept, for how long, in what form, how it is retrieved, and what happens when a customer asks for a package three years after despatch. Retention periods are frequently set by customer contract and exceed the standard's default — your people need to know yours.

Handling, storage and shelf life. Shelf-life control, ESD-sensitive items, foreign object prevention, segregation of serviceable from unserviceable and obsolete stock, and the control of scrap so that scrapped material cannot re-enter the chain. Scrap control is often the weakest link, and it is the one with the worst consequences.

Who needs training, and at what depth

Distribution teams are usually small, which makes the role-matching easier than it is in a factory.

• Goods-in and stores. Arguably the most important group. They are the control point for traceability, documentation completeness, damage, shelf life and counterfeit detection. Train them properly and specifically, on your own incoming paperwork.
• Sales and purchasing. They create the exposure. Approved source control, customer requirement flow-down, and the discipline of not accepting an order with requirements the business cannot evidence.
• Quality. The standard in depth, plus internal auditing against it.
• Management. Enough to understand where the risk sits and to back a decision to quarantine stock that someone is waiting for.

Train on your own certification packages

The same principle applies here as anywhere: use your own records.

Take a real incoming consignment, with its real certificate package, and have the team work through whether the traceability is complete. Take a real split transaction and follow the identity through. Take a customer's quality clauses and trace them back to what you actually flow down to your supplier.

It is uncomfortable and it is where the value is. On courses run this way I have seen teams find incomplete trace documentation on stock already on their shelves — which is far better found in a training room than in a customer audit or, worse, after an installed part is questioned.

The point most distributors miss

Aerospace distribution is a trust business. Your customer is relying on you to have preserved something they cannot verify themselves once the part is in their hands.

That is why the standard cares so much about things that look like administration. A missing certificate is not a filing error — it is a part whose identity can no longer be proven, which in practice means a part that cannot be used. Training that frames the paperwork as compliance overhead teaches the wrong lesson. Training that frames it as the thing being sold teaches the right one.

Frequently asked questions

Can our team attend an AS9100 course instead?

They can, and they will learn the common ground — the management system structure, risk, nonconformity, internal audit. But a significant part of the course will cover design and production control they do not perform, and the areas that actually carry their audit risk will get little attention. For quality staff it can be a reasonable supplement; for goods-in and stores it is largely wasted.

Do we need AS9120 certification, or is AS9100 enough?

AS9120 is the appropriate standard for a stockist or distributor that does not manufacture. Some customers specify it directly. If you both manufacture and distribute, scope matters and is worth getting advice on before you commit to a certification route.

How much training do goods-in staff really need?

Less than you might think in hours, more than most businesses give them in depth. A focused half-day on traceability, documentation completeness, counterfeit indicators and shelf life, taught on your own incoming paperwork, covers most of the exposure. Repeat it when people change or when a near miss occurs.

Who should deliver it?

Someone who has audited distributors, not only manufacturers. The failure modes are different, and the useful examples come from having seen them.

We deliver AS9120 training built around your own stock, certification packages and procedures, and carry out internal and second-party audits on our clients' behalf. See our training services, our quality management work, or get in touch.
