Aerospace Quality (AS9100D)

AS9100 is the quality management standard for the aviation, space, and defense (AS&D) industry. The current revision is AS9100D. It is published through the SAE and IAQG (International Aerospace Quality Group) family of standards and is used worldwide — you will see the same requirements under the EN 9100 and JISQ 9100 designations in Europe and Asia.

Like the other aerospace standards, AS9100 is built on ISO 9001. It takes the full ISO 9001 management-system framework and adds the requirements that aviation, space, and defense demand — because in this industry a single nonconforming part can put lives and missions at risk. So AS9100D is ISO 9001 plus aerospace-specific requirements around risk, configuration management, product safety, counterfeit-part prevention, and rigorous traceability.

It is worth knowing the family it sits in. AS9100 is for organizations that design and/or manufacture aerospace products. AS9110 is the version for maintenance, repair, and overhaul (MRO) organizations. AS9120 is for stockist distributors — companies that buy, hold, and resell aerospace parts. Same DNA, different scope.

AS9100 is for organizations that design, develop, or manufacture products for the aviation, space, and defense sectors — anywhere in the supply chain, from primes down to small machine shops.

It is a fit for:

• Manufacturers of aircraft, spacecraft, or defense parts, assemblies, and systems
• Companies that design aerospace components or products
• Suppliers of raw materials, fasteners, castings, forgings, and electronics for aerospace use
• Providers of special processes — heat treatment, non-destructive testing, plating, welding, coatings
• Manufacturers looking to enter the aerospace supply chain and qualify with a prime or Tier 1

If you are an MRO shop, the right standard is usually AS9110; if you are a distributor of aerospace parts, it is usually AS9120. As with automotive, certification is typically required by your customer — the primes (think Boeing, Airbus, Lockheed Martin and their major suppliers) flow AS9100 down as a condition of doing business. Certified organizations are also listed in OASIS, the industry's online supplier database, which is where customers go to check your status.

AS9100D keeps every ISO 9001 requirement and adds the aerospace layer on top. The additions reflect what happens when the stakes are safety-critical:

• Risk management woven through operations — identifying, assessing, and controlling risk in your processes and products, not just planning for it abstractly
• Configuration management — knowing exactly which design, revision, and build state applies to every product, and keeping it consistent through changes
• Counterfeit-parts prevention — controls to keep suspect and counterfeit materials out of your supply chain and your product
• Product safety — explicit attention to the safety of the product throughout its life cycle
• First Article Inspection (FAI) — a full, documented verification that the first production part meets every requirement
• Rigorous traceability and record control, often down to the material heat-lot and individual serial number
• Tight control of special processes and of the suppliers who perform them
• Foreign object debris (FOD) prevention and control of nonconforming product

The whole standard is oriented toward one idea: on-time delivery of conforming, safe product, with the evidence to prove it.

The first reason is access. Aerospace primes and their major suppliers require AS9100 from the organizations they buy from, and they check the OASIS database to confirm it. Without the certificate, you generally cannot bid — with it, you become a qualified, findable supplier in a market that values long, stable relationships.

Beyond market access, the discipline pays off. Configuration management and strong traceability mean you always know what you built and can prove it — invaluable when a customer asks or an issue arises years later. Risk management and FAI catch problems before parts ship. Counterfeit-part and FOD controls protect you from some of the most expensive and reputation-damaging failures in the industry.

Aerospace customers also score their suppliers hard on quality and delivery. A robust AS9100 system directly improves those ratings, and in a sector where programs run for decades, a strong rating is what keeps you on the next contract and the one after that.

We bring 30+ years of building quality systems and a record of 900+ organizations certified with a 100% first-time pass rate. Aerospace is unforgiving on documentation and traceability, and our 10-Step Approach is built to get it right the first time.

We begin by understanding your products, your processes, and the requirements your customers flow down to you. We build the system with your team — configuration management, risk, FAI, counterfeit-part and FOD controls included — so it fits how you actually operate rather than forcing you into a generic template. We train your people so they can run and defend the system after we are gone.

As with all our work, you get single-level documentation, typically under 200 pages for the whole system — lean enough that people use it, complete enough to satisfy an aerospace auditor. We run internal audits and management review, then support you through the Stage 1 and Stage 2 certification audits and your OASIS listing. Most organizations reach certification in about 6 to 10 months, depending on complexity and starting point.

• Choosing the wrong standard — using AS9100 when your operation is really MRO (AS9110) or distribution (AS9120)
• Missing requirements the prime flowed down to you, then discovering the gap during an audit or a customer complaint
• Weak configuration management, so you cannot reliably prove which revision and build state you shipped
• Treating risk management as a one-time form instead of a live part of running operations
• Incomplete or sloppy First Article Inspection records that do not stand up to scrutiny
• No real counterfeit-part or FOD program until an auditor or a customer asks for one
• Traceability gaps at the material or serial-number level that surface only when there is a problem in the field
• Heavy multi-tier manuals that people ignore, so the documented system and the real one drift apart
