🛡️ Quality Control Process

Compliant with NADCAP / AS9100 / ISO 9001

1️⃣ Raw Material Control

 Key Control Points (KCP): Material Traceability / Certificate of Conformance

• All materials (e.g., Ti-6Al-4V, Inconel 718) are sourced from pre-approved suppliers listed in the ASL (Approved Supplier List).
• Each batch is accompanied by a Mill Test Report (MTR) with full heat number traceability.
• Materials conform to aerospace standards such as AMS 4928 / AMS 5662.
• Incoming inspection includes chemical and mechanical property verification (where applicable).

2️⃣ Process Control

 KCP: Process Validation / Work Instructions / Special Process Oversight

• All manufacturing steps follow validated Process Flow Charts (PFC) and detailed Work Instructions (WI).
• CAM toolpaths are verified through simulation software (Mastercam, NX) prior to execution.
• Welding, heat treatment, and surface coating are executed by NADCAP-accredited subcontractors with documented qualifications.

3️⃣ First Article & In-Process Inspection

 KCP: AS9102 FAI / In-Process Control Plan

• FAI is conducted in accordance with AS9102 Rev. B to ensure full compliance with design specifications.
• Statistical Process Control (SPC) is applied to Critical-to-Quality (CTQ) features during production.
• All gauges and Coordinate Measuring Machines (CMMs) are calibrated and traceable to national standards.

4️⃣ Functional & Performance Testing

 KCP: Test Plan / Functional Qualification / Acceptance Criteria

• Where applicable (e.g., for rotating components), rotor dynamic balancing and vibration testing are performed.
• Mechanical integrity tests such as tensile and fatigue testing are performed on sample coupons.
• Each rotor is inspected for airfoil geometry and profile accuracy.

5️⃣ Special Process Management (if applicable)

 KCP: NADCAP Accreditation / Process Certification

• Special processes (e.g., electron beam welding, thermal barrier coatings) are executed by NADCAP-certified partners.
• Each process step is supported by Process Approval Records and operator qualifications.

6️⃣ Final Inspection

 KCP: Dimensional Check / Surface Quality / Conformance Documentation

• Full dimensional inspection conducted using CMM based on 3D CAD models and drawings.
• Surface finish (Ra ≤ 0.8μm) and edge radii are verified.
• Certificate of Conformance (COC) is issued upon successful final inspection.

7️⃣ Documentation & Traceability

 KCP: Document Control / Lot Traceability / Record Retention

• Each IBR is fully traceable via a unique serial number.
• Documentation package includes Process Routers, QC Reports, Test Results, and MTRs.
• All records are retained for a minimum of 10 years in compliance with AS9100 Clause 7.5.
