Why India Is Becoming the World's Preferred Aerospace Supply Partner
The global aerospace industry does not forgive errors. A single defective bracket, an improperly treated alloy or a missed delivery can ground an aircraft, delay a program or cause a safety incident. That is precisely why global OEMs like Boeing, Airbus, Collins Aerospace and Safran are increasingly selective about where they source their precision components—and why aerospace component suppliers in India are rapidly earning their trust.
India's aerospace manufacturing ecosystem has undergone a powerful transformation over the last decade. What was once a largely import-dependent market has evolved into a genuine global supply hub, producing structural airframe components, actuation system parts, cargo hardware, landing gear elements, seating structures, avionics assemblies and engine accessories for the world's most popular commercial aircraft.
According to Dun & Bradstreet's business directory, there are over 12,000 aerospace product and parts manufacturing companies registered in India, spread across Karnataka, Maharashtra, Gujarat, Tamil Nadu and Telangana. Of these, a growing number are AS9100 Rev D certified, NADCAP-approved for special processes and actively supplying Tier-1 and OEM customers globally.

What Is AS9100 Certification and Why Every Global OEM Demands It
AS9100 is the internationally recognised quality management system standard for the aviation, space, and defence industries, published by the International Aerospace Quality Group (IAQG). It builds on ISO 9001 by adding requirements specific to aerospace: risk management, configuration management, first article inspection, product safety, key characteristics and counterfeit parts prevention.
The current revision, AS9100 Rev D, was released in 2016. No reputable global OEM or Tier-1 company will consider a supplier without an active AS9100 certificate. An AS9100 certified supplier must demonstrate:
- A documented quality management system covering all processes from order intake to delivery
- Process validation procedures for critical manufacturing steps including machining, heat treatment, plating and assembly
- Configuration management ensuring every part matches its approved design, revision by revision
- First Article Inspection (FAI) capability using AS9102 methodology
- Counterfeit part prevention policies across procurement and receiving inspection
- Key characteristics management controlling dimensions and process parameters affecting fit, function and safety
- Third-party certification audits by IAQG-registered bodies such as DNV, Bureau Veritas, TÜV SÜD and Intertek
- Surveillance audits every twelve months and full re-certification every three years
Buyers should always verify AS9100 certificates on the IAQG OASIS (Online Aerospace Supplier Information System) database, checking scope, expiry date and certifying body.
Material Traceability in Aerospace: What Global OEMs Require
Material traceability means linking every individual part back to the specific raw material from which it was made—including the material heat number, mill certificate, chemical composition, mechanical properties and all subsequent processing records for heat treatment, surface treatment, machining, inspection and final acceptance.
The Chain of Traceability: From Mill to Aircraft
- Raw material mill certificate: Every material input must arrive with a mill test certificate (MTC) from an approved supplier, certifying chemical composition and mechanical properties to the applicable material specification (AMS, ASTM or equivalent).
- Incoming inspection: Quality teams verify the MTC against purchase specifications and assign an internal lot or heat number that travels with the material through every subsequent operation.
- Traveller documents: Every machining, heat treatment, plating and inspection activity is recorded on a traveller document tying back to the material lot, operator, machine ID, process parameters and date.
- Special process certificates: For heat treatment, NDT, plating, shot peening and anodising, NADCAP-approved providers must supply processing certificates detailing cycle parameters and conformance to the applicable process specification.
- Dimensional inspection records: CMM reports, surface finish measurements and hardness test results are retained per part or lot with traceability to material and process records.
- Certificate of Conformance: The final CoC issued with each shipment summarises part number, revision, quantity, serial/lot number, material specification and declares conformance to drawing and purchase order requirements.
NADCAP: The Special Processes Layer
For special processes such as heat treatment, non-destructive testing (NDT), chemical processing and shot peening, the aerospace industry relies on NADCAP (National Aerospace and Defence Contractors Accreditation Program) accreditation. NADCAP-approved processors have been audited against the most stringent special process requirements—routinely required by Boeing, Airbus, GE Aviation, Pratt & Whitney and Rolls-Royce. Indian suppliers who cannot perform special processes in-house must route work through NADCAP-approved external providers with full documentation.
What Global OEMs Demand from Aerospace Suppliers
The demands from global OEMs including Boeing, Airbus, Collins Aerospace, SAAB and Meggitt are comprehensive and non-negotiable:
- AS9100 Rev D Certification: Mandatory for all
- NADCAP for Special Processes: Required for all
- First Article Inspection (AS9102): Mandatory for all
- On-Time Delivery KPI: ≥97-99% depending on customer
- PPM Quality Target: Near Zero to Zero PPM
- Counterfeit Part Prevention: Mandatory for all
