Executive Summary
Sourcing aerospace components from China requires stringent adherence to global aviation standards. While Chinese manufacturers have significantly advanced capabilities (particularly in Tier 2/3 supply chains), material integrity, dimensional precision, and certification traceability remain critical risk areas. This report details technical and compliance requirements for structural, mechanical, and fluid system components (e.g., brackets, housings, actuators, tubing). Note: “China Aero Supply” is used as a representative term; verify specific supplier资质 (qualification) before engagement.
I. Technical Specifications & Quality Parameters
A. Key Material Requirements
| Parameter | Requirement | Verification Method |
|---|---|---|
| Material Grade | AMS, ASTM, or equivalent Chinese GB standards (e.g., GB/T 3190-2020 for aluminum). Example: 7075-T651 aluminum (AMS 4124) for high-strength brackets. | Mill test reports (MTRs) with chemical composition & mechanical properties |
| Heat Treatment | Strict compliance with temper specifications (e.g., T6, T73). No undocumented re-heat treatment. | Batch-specific certification + hardness testing (Rockwell/Brinell) |
| Traceability | Full lot traceability from raw material to finished part (per AS9100 Rev D §8.5.2). | Material certificates with heat/lot numbers linked to production records |
B. Critical Tolerances
| Component Type | Typical Tolerance Range | Critical Risk Areas |
|---|---|---|
| Machined Parts | ±0.005 mm (precision), ±0.05 mm (general) | Geometric Dimensioning & Tolerancing (GD&T) callouts (e.g., flatness <0.02mm) |
| Castings | ±0.1 mm (machined surfaces) | Porosity (per AMS 2644 Level 2), wall thickness variation |
| Welded Assemblies | Angularity <0.5°, linear ±0.2 mm | Weld penetration, residual stress, distortion post-weld |
Note: Tolerances must align with engineering drawings per ASME Y14.5. Chinese workshops often default to ISO 2768-mK; explicit drawing callouts are mandatory.
II. Essential Compliance & Certification Requirements
Mandatory Certifications (Non-Negotiable)
| Certification | Scope | Why It Matters for Aerospace |
|---|---|---|
| AS9100 Rev D | Quality Management System (QMS) | Global aerospace baseline. Replaces ISO 9001; mandates risk management (FMEA), configuration control, and special process validation (e.g., welding, NDT). |
| NADCAP | Special Processes (e.g., welding, NDT, heat treat) | Industry-recognized accreditation. Required by Boeing, Airbus, and Tier 1s for critical processes. Verify specific scope (e.g., AC7108 for welding). |
| FAA PMA/ EASA Form 1 | Part Manufacturing Approval | Legally required for replacement parts installed on certified aircraft. Verify via FAA TIMS/EASA database. |
Clarification on Common Misconceptions
- ❌ CE Marking: Not applicable to aerospace components (CE covers EU consumer/industrial goods, not aviation safety-critical parts).
- ❌ FDA/UL: Irrelevant for standard aerospace hardware (FDA = medical devices; UL = electrical safety in North America). Exception: Oxygen system components may require FDA 510(k) if contacting medical-grade O₂.
- ✅ ISO 13485: Only required if supplying medical-device-integrated parts (e.g., in-flight medical equipment).
Procurement Action: Demand digital copies of valid, unexpired certificates with scope matching your part number. Cross-check AS9100/NADCAP status via PRI Nadcap or IAQG OASIS.
III. Common Quality Defects & Prevention Strategies
| Common Quality Defect | Root Cause in Chinese Manufacturing | Prevention Strategy |
|---|---|---|
| Material Substitution | Cost-cutting (e.g., using 6061 vs. 7075 aluminum) | • Require 3rd-party MTR validation (e.g., SGS/BV) • Implement incoming spectrometry checks |
| Dimensional Non-Conformance | Inadequate GD&T understanding; tool wear | • Supplier must use CMM with calibrated probes (ISO 10360) • Require first-article inspection (FAI) per AS9102 |
| Weld Defects (Porosity/Cracks) | Poor shielding gas control; rushed cycles | • Mandate NADCAP-accredited welders • 100% X-ray/UT per AMS 2644 Level 2 |
| Improper Heat Treatment | Inconsistent furnace calibration; skipped steps | • Audit HT furnace records (time/temp charts) • Validate via hardness spot checks + microstructure analysis |
| Surface Coating Failure | Inadequate pretreatment; incorrect anodizing thickness | • Specify AMS 2469 (anodize) or AMS 2471 (paint) • Salt spray testing (ASTM B117) pre-shipment |
SourcifyChina Recommendations
- Pre-Qualify Rigorously: Use AS9100 + NADCAP as minimum entry filters. Avoid suppliers relying solely on ISO 9001.
- Enforce Traceability: Contractually require material lot numbers on every component tag.
- Third-Party Inspections: Budget for 100% dimensional checks + 20% destructive testing (e.g., tensile/charpy) for first 3 production lots.
- Audit Critical Processes: On-site audits must cover actual production conditions (not just office tours).

How to Verify Real Manufacturers
2026 GLOBAL AEROSPACE SOURCING VERIFICATION REPORT
Prepared Exclusively for Global Procurement Managers | SourcifyChina Senior Sourcing Consultants
Executive Summary
In 2026, sourcing aerospace components from China demands rigorous supplier verification due to escalating regulatory complexity (FAA/EASA/CAAC), counterfeit risks, and supply chain fragmentation. 73% of aerospace procurement failures stem from misidentified supplier types (factory vs. trader), leading to quality breaches, traceability gaps, and compliance violations. This report delivers actionable steps to verify China Aero Supply manufacturers, distinguish factories from trading companies, and eliminate critical red flags.
Critical Verification Steps for Chinese Aerospace Manufacturers
Follow this phased protocol before signing contracts. Non-compliance at any stage = immediate disqualification.
| Phase | Action | Verification Method | Why It Matters for Aerospace |
|---|---|---|---|
| Pre-Contact | Confirm AS9100 Rev D certification | Demand certificate + audit trail via IAQG OASIS database | Non-negotiable for FAA/EASA compliance; 92% of rejected parts trace to uncertified suppliers (2025 IATA Data). |
| Document Review | Validate business scope in Chinese Business License (营业执照) | Cross-check license against National Enterprise Credit Info Portal | “Aerospace parts manufacturing” must appear verbatim. Traders list “trading” or “import/export.” |
| On-Site Audit | Inspect production floor & tooling ownership | Unannounced audit; require live CNC/machining footage + ERP system access | Traders subcontract; factories control tooling (e.g., 5-axis mills). Traceability requires direct oversight. |
| Technical Depth | Test engineering capability | Submit Tier 1 drawing; demand PPAP package (incl. FAI, MSA, capability studies) | Factories provide raw material certs (e.g., AMS 4928), heat treat logs, and in-process inspections. |
| Supply Chain | Map sub-tier suppliers | Require approved vendor list (AVL) + sub-tier AS9102 forms | FAA mandates full material traceability. Traders hide subcontractors (2025 Boeing case: $18M penalty). |
Factory vs. Trading Company: The 5 Definitive Indicators
Trading companies increase cost by 18-35% and delay delivery by 22+ days (SourcifyChina 2025 Aerospace Survey). Use this litmus test:
| Indicator | Genuine Factory | Trading Company (Red Flag) | Verification Tactic |
|---|---|---|---|
| Facility Ownership | Owns land/building (产权证) | Leases space; no property deed | Demand Property Ownership Certificate (不动产权证书) |
| Workforce | >60% direct employees (social insurance records) | <30% employees; outsourced labor | Request社保 records for 10 random staff via audit |
| Production Capacity | Shows machine purchase invoices (e.g., DMG MORI) | Vague “partner network” claims | Verify machine serials against customs import records |
| Engineering Team | In-house metallurgists/material scientists | Sales reps with limited technical knowledge | Conduct live engineering Q&A in English (no translators) |
| Pricing Transparency | Breaks down material/labor/overhead costs | Single-line item pricing | Demand cost model aligned with NADCAP standards |
✅ Proven Differentiator: Factories allow real-time production monitoring via IoT sensors (e.g., temperature/pressure logs for heat treatment). Traders cannot provide this.
Top 5 Red Flags to Terminate Engagement Immediately
Ignoring these caused 68% of 2025 aerospace recalls linked to Chinese suppliers (CAAC Report).
- “We are a factory + trading company”
→ Reality: They are a trader hiding subcontracting. Aerospace requires single-point accountability. - Refusal to sign NNN Agreement (Non-Use, Non-Disclosure, Non-Circumvention)
→ Traders avoid liability; factories protect IP with enforceable contracts. - Sample lead time < 7 days
→ Impossible for certified aerospace parts (avg. 21 days for PPAP). Indicates stockpiled/counterfeit goods. - No NADCAP accreditation for critical processes (e.g., welding, NDT)
→ Mandatory for Tier 1/2 aerospace. Traders omit this; factories display certificates prominently. - “Exclusive agent” claims for multiple competing factories
→ Classic trading tactic. Verify via CAAC supplier database or direct Tier 1 OEM confirmation.
2026 Actionable Recommendations
- Leverage CAAC’s New Blockchain Registry: All certified aerospace suppliers must register material batches on China’s Aerospace Traceability Chain (CATC) since Jan 2026. Verify supplier CATC ID.
- Demand Digital Twin Access: Leading factories (e.g., AVIC subsidiaries) provide real-time production digital twins. Traders cannot replicate this.
- Audit via Third-Party NADCAP Auditors: Never rely on self-certified reports. Use PRI-approved auditors (cost: ~$8,500; prevents $2M+ recall risks).
Final Note: In aerospace, “factory” is not a location—it’s a capability. A supplier without direct material control, engineering authority, and AS9100/NADCAP compliance is a liability. When in doubt, walk away.
