Aerospace Manufacturing in Mexico: Meeting AS9100 Without Sacrificing Speed
Meeting AS9100 in Mexico no longer requires months of searching or depending on a single supplier. We explain what aerospace OEMs demand and how to manage the supply chain without losing speed.
Getting certified aerospace manufacturing in Mexico is not the problem — the problem is getting it on time. Aerospace OEMs and Tier 1s require AS9100, a complete FAI, and material traceability from the first lot. That does not have to mean months of searching or depending on a single supplier that dictates timelines and prices.
At a Glance
- AS9100 Rev D is the floor, not the ceiling — without it, no aerospace OEM will accept your machining suppliers
- FAI (First Article Inspection) dimensionally validates the first produced article before authorizing volume, following the AS9102B standard
- Material traceability means heat number, AMS certificate, and lot linked to each part — not optional documentation obtained after the fact
- Certifying a new shop takes 6 to 18 months — an already-certified network eliminates that bottleneck on the buyer's side
- Radii filters its network for aerospace projects: only shops with current AS9100 Rev D enter the quoting chain — see partner network
The aerospace industry in Mexico is the country's third-largest manufacturing export sector. More than 350 active companies form a supply chain stretching from Hermosillo to Querétaro. The capacity exists. What is often missing is visibility into who is genuinely certified, who has available capacity, and who can deliver with the complete documentation the OEM requires.
An aerospace buyer faces three simultaneous pressures: the OEM auditing down the supply chain, a production schedule that does not wait, and a budget with no room for rework surprises or missing certifications. AS9100 resolves the first — but only if the supplier has it current, properly implemented, and can demonstrate it with real records, not just a framed certificate on the wall.
1. What AS9100 Requires — and Why It Is Not Just a Paper on the Wall
AS9100 Rev D is the current version of the quality management standard for aviation, space, and defense. It is based on ISO 9001:2015 with additional requirements that make a real difference in production:
Operational risk management. Unlike ISO 9001, AS9100 requires identifying and managing risks in the production process — not only in the management system. This translates into documented process FMEAs and part-specific control plans.
Full traceability. Every material used must be traceable to its origin: heat number, certificate of chemical analysis, applicable AMS specification. A part without full traceability is a nonconformance. In aerospace, that is non-negotiable.
Nonconforming parts management. AS9100 is explicit about how to identify, segregate, and disposition materials or parts that do not conform. In a shop without AS9100, that process may or may not exist — and you will not know until a real problem occurs.
Qualified personnel competence. The standard requires that those operating special processes — welding, heat treatments, coatings — be qualified to customer specifications or standards such as Nadcap, where applicable.
2. The FAI: The Step No OEM Skips
The First Article Inspection closes the loop between design and serial production. Before a supplier delivers volume, the customer verifies that the first produced article meets 100% of the drawing — dimensions, tolerances, finishes, and materials.
The FAI report follows the AS9102B standard and includes three formal sections:
Section 1 — Design Documentation. Confirms the supplier has the correct drawing revision, applicable specifications, and understands every customer requirement.
Section 2 — Product Accounting. Documents materials used with mill certificates, special processes applied (with their current qualifications), and any externally purchased components.
Section 3 — Characteristic Accountability. Measures and records every dimension, tolerance, and finish specified on the drawing. Each characteristic requires a nominal value, measured value, and declared conformance. There are no shortcuts — if the drawing has 200 dimensions, the report has 200 lines.
A rejected FAI delays entry into production. Accelerating the FAI does not mean skipping steps — it means working with a supplier that has the process documented and the calibrated measurement equipment to execute it cleanly on the first attempt.
3. Material Traceability: What OEMs Actually Audit
When an OEM audits its Tier 1, and that Tier 1 audits its machining suppliers, the question is always the same: "Show me where the material in this part came from."
The correct answer is a material certificate that includes:
- Applicable specification (AMS 4928 for Ti-6Al-4V, AMS 2770 for heat treatments, etc.)
- Mill heat/lot number
- Chemical analysis of the lot
- Mechanical properties where applicable
- Name of the mill or authorized distributor
Purchasing material on the open market without a mill certificate is an audit finding. It is not a minor defect — it signals that the material control system does not work. On aerospace projects via Radii, material certificates are an order requirement, not documentation requested after the fact.
4. Managing Multiple AS9100 Suppliers Without Losing Control
The real challenge for aerospace buyers is not finding one AS9100 supplier — it is managing four or five simultaneously, each with different capabilities, workloads, and response speeds, without consuming all of the procurement and quality team's time.
When every quote requires an email, a phone call, and 48 hours of waiting, sourcing becomes a bottleneck. When every supplier has its own quality documentation format, the team spends more time standardizing paperwork than reviewing parts.
A manufacturing platform addresses that differently:
- Simultaneous quoting — one specification sent to multiple AS9100 shops, comparable prices in minutes instead of days. See how it works
- Standardized documentation — same certificate structure and quality deliverables regardless of which shop produces
- Visible capacity — you know who has available time before committing a program
- One point of contact — instead of managing four separate relationships
That is not sacrificing certification — it is making AS9100 work in parallel with the speed a real aerospace program demands.
The Radii partner network includes shops with current AS9100 Rev D for precision CNC machining. For programs with multiple part numbers or high volumes, the supply chain team can structure sourcing from the first quote.
Frequently Asked Questions
What is AS9100 and why do aerospace OEMs require it?
AS9100 is the international quality management standard for the aerospace industry, based on ISO 9001 with additional sector-specific requirements. OEMs such as Boeing, Airbus, and GE Aviation require it because it establishes rigorous controls over material traceability, process documentation, risk management, and nonconforming parts prevention. Without AS9100, a supplier cannot enter the aerospace supply chain.
What is a FAI (First Article Inspection) and when is it required?
The FAI is a documented process that verifies the first produced article meets exactly the design requirements and customer specifications. It is required when starting production with a new supplier, when changing materials or production process, and after any significant production pause. The result is an AS9102B report that the customer approves before authorizing serial production.
How does Radii guarantee material traceability on aerospace projects?
Radii requires material certificates with heat number, AMS specification or equivalent, and production lot for every aerospace order. These documents are digitally linked to each produced part. If there is a nonconformance, it is possible to trace exactly which material was used, on which machine, and on which date — which is exactly what OEMs audit.
How long does it take to certify an AS9100 supplier?
A new AS9100 certification takes between 6 and 18 months, depending on the initial state of the shop's quality management system. The maintenance audit cycle is annual. Working with an already-certified network eliminates that waiting time on the buyer's side.
Can a manufacturing platform meet AS9100 the same way a specialized shop can?
Yes, as long as the shops in the network are individually AS9100-certified and the platform has documented audit and traceability processes. Radii only includes shops with current AS9100 Rev D for aerospace projects, and quality follow-up is managed centrally — a single point of contact without sacrificing the controls the OEM requires.

- Material traceability means mill certificate, heat number, and lot linked to each part, without exception
- Certifying a new shop takes 6 to 18 months; an already-certified network eliminates that bottleneck
