MIIT Mandates Full AS9102 Form 1–3 Inspection for Exported 3D-Printed Ti Aircraft Parts

On May 8, 2026, China’s Ministry of Industry and Information Technology (MIIT) issued an urgent notice requiring full AS9102 Form 1–3 inspection documentation for all industrial-grade additively manufactured titanium alloy aviation components exported to jurisdictions under FAA or EASA airworthiness regulation — including flight control housings and landing gear connectors. This directive directly impacts aerospace component exporters, certified testing labs, and Tier-1/2 manufacturers supplying into global civil aviation supply chains.

Event Overview

On May 8, 2026, MIIT’s Department of Equipment Industry I released the Notice on Quality Control for Exported Additively Manufactured Critical Aviation Components. It stipulates that all industrial 3D-printed titanium alloy aviation parts destined for FAA- or EASA-regulated markets must be accompanied by complete AS9102 documentation: Form 1 (First Article Inspection Report), Form 2 (Process Inspection Record), and Form 3 (Final Inspection Report). All reports must be issued by laboratories accredited by the China National Accreditation Service for Conformity Assessment (CNAS). The notice has prompted urgent capacity expansion in inspection capabilities at multiple aviation material plants in Xi’an and Chengdu.

Industries Affected

Export-Oriented Aerospace Component Manufacturers

These manufacturers are directly subject to the new requirement. Non-compliance risks rejection of export shipments, delays in airworthiness certification, and potential contractual penalties with OEMs or Tier-1 suppliers operating under FAA/EASA oversight.

CNAS-Accredited Testing Laboratories

Labs issuing AS9102 reports must now validate their scope explicitly covers additive manufacturing processes for titanium alloys — particularly for geometry, metallurgical properties, and non-destructive evaluation (NDE) methods aligned with AS9102. Capacity constraints may emerge as demand surges, especially among labs without prior AM-specific accreditation.

Tier-2 Material & Process Suppliers

Suppliers providing powder feedstock, build parameters, or post-processing services (e.g., HIP, stress relief, surface finishing) may face increased traceability demands. Their process records and material certifications may be audited as part of the Form 2 submission, even if they do not issue the final AS9102 report.

Aerospace Supply Chain Integrators

Firms consolidating components from multiple subcontractors must ensure end-to-end AS9102 compliance across the entire assembly chain — including sub-assemblies containing 3D-printed titanium parts. Gaps in documentation from any tier could invalidate the full Form 1 package.

What Enterprises and Practitioners Should Focus On and How to Respond

Monitor official updates from MIIT and CAAC on implementation timelines and scope clarifications

The notice is titled a “quality control reminder,” not a formal regulation. Analysis shows its enforceability may depend on subsequent guidance from the Civil Aviation Administration of China (CAAC) or integration into export licensing procedures — making near-term policy tracking essential.

Prioritize verification of CNAS lab scope for AM-specific titanium inspection capabilities

Not all CNAS-accredited labs currently list additive manufacturing process validation or titanium alloy microstructure analysis (e.g., alpha-beta phase quantification, pore distribution per ASTM F3049) within their approved scope. Companies should audit lab credentials before initiating first-article inspections.

Distinguish between regulatory signal and operational readiness

Observably, the requirement reflects tightening alignment with international aviation quality expectations — but does not yet introduce new domestic production standards for non-exported parts. Export-focused operations should treat this as binding; domestic-only producers may see limited immediate impact.

Initiate cross-functional alignment on documentation handoffs and data traceability

AS9102 Form 2 requires real-time process monitoring data (e.g., layer-by-layer thermal history, recoater performance logs, gas purity records). Manufacturers should confirm internal systems can extract, version-control, and archive such data — and define clear ownership between design, production, and quality teams.

Editorial Perspective / Industry Observation

This notice is better understood as a procedural calibration than a standalone regulatory shift. From an industry perspective, it formalizes existing de facto expectations from foreign OEMs and regulators — converting implicit supply chain requirements into explicit national-level export gatekeeping criteria. Analysis suggests it signals MIIT’s intent to strengthen China’s position in high-integrity AM exports, rather than impose broad technical restrictions. However, its operational impact hinges on enforcement consistency and coordination with CAAC and customs authorities — factors still evolving and therefore warranting continued observation.

It is not yet a completed policy framework, but rather an early-stage quality governance marker. Its significance lies less in novelty and more in institutional recognition: that AM-produced titanium parts entering global civil aviation markets must meet the same evidentiary rigor as conventionally manufactured counterparts — down to the level of first-article validation and process record integrity.

Consequently, stakeholders should track how this notice interacts with upcoming revisions to GB/T 35021 (Chinese standard for metal AM) and CAAC’s forthcoming guidance on AM part certification — both currently under development.

In summary, this directive marks a step toward harmonized export discipline for AM aviation parts, not a sudden barrier. It underscores that documentation integrity — not just part performance — is now a core export requirement. For affected enterprises, proactive alignment with AS9102’s evidentiary logic is more strategic than reactive compliance.
