- Verify the supplier's manufacturing capabilities align with your specific component's requirements, such as 5-axis CNC machining for complex turbine blades, superplastic forming for aerospace sheet metal parts, or filament winding for composite pressure vessels. Ensure they can handle the specified material (e.g., Inconel, Titanium, Carbon Fiber Pre-preg) and achieve the necessary tolerances, typically measured in ten-thousandths of an inch for critical interfaces.
- Demand documented proof of relevant quality certifications like AS9100 for their Quality Management System. For special processes such as welding, heat treatment, NDT (Non-Destructive Testing), or surface finishing, always confirm current NADCAP accreditation specific to the process you require, as this ensures validated, repeatable results critical for flight safety.
- Scrutinize their documentation control and traceability systems. A significant red flag is any reluctance or inability to provide comprehensive material certifications (CofCs) tracing back to the mill, along with robust First Article Inspection (FAI) reports (AS9102 format is standard) and evidence of Conformity of Production (COP). For any component that might fall under export control, verify their ITAR compliance registration and internal procedures.
- Differentiate between OEM-focused Tier 1/2 suppliers accustomed to high-volume, long-term contracts and smaller, more agile shops that might be better suited for prototype runs, niche PMA parts, or legacy component production. Consider their capacity for both your initial production run and anticipated ramp-up, and assess their experience in managing the specific regulatory approvals (e.g., FAA Part 21G, EASA Part 145) pertinent to your component's end use.
Supplier Types at a Glance
| Type | Best For | Typical MOQ |
|---|---|---|
| OEM Tier 1/2 Manufacturer | High-volume, new aircraft programs, complex systems, long-term contracts | High (thousands+) |
| Specialty Machining & Fabrication Shop | Precision components in exotic materials, specific sub-assemblies, prototype to mid-volume | Low to Medium (tens to hundreds) |
| PMA/MRO Aftermarket Specialist | Sourcing for legacy aircraft, obsolete part replacement, reverse engineering, FAA-approved alternatives | Very Low to Medium (single units to dozens) |
| Advanced Composites/Additive Manufacturer | Lightweight structures, complex internal geometries, next-gen materials, R&D projects | Low (prototypes to small batches) |
Frequently Asked Questions
What's the difference between a manufacturer holding FAA Part 21 Production Approval and one producing under a Part Manufacturer Approval (PMA)?
An FAA Part 21 Production Approval holder manufactures parts under the design and quality system specified by an Original Equipment Manufacturer (OEM) Type Certificate. These parts are typically new, directly from the aircraft designer. A Part Manufacturer Approval (PMA) holder, however, produces replacement parts that are not made by the original manufacturer but have been approved by the FAA for installation on a type-certificated aircraft. PMA parts must demonstrate equivalent safety, performance, and reliability to the original part, often offering cost savings for aftermarket applications but requiring careful evaluation of the approval basis (e.g., Test and Conformity, Identicality) and the manufacturer's quality system.
How critical is NADCAP accreditation for my aircraft component supplier, and what processes does it cover?
NADCAP (National Aerospace and Defense Contractors Accreditation Program) accreditation is exceptionally critical for any supplier performing special processes on flight-critical components. Unlike general ISO certifications, NADCAP ensures rigorous, industry-specific oversight and validation of a manufacturer's adherence to stringent aerospace process controls. It covers a vast array of processes including heat treating, chemical processing (e.g., anodizing, plating), welding, non-destructive testing (NDT), surface enhancement (e.g., shot peening), composites fabrication, and conventional machining, guaranteeing that these processes are performed consistently and reliably to aerospace standards.
What are the non-negotiable traceability requirements I should demand for flight-critical components?
For flight-critical components, absolute traceability is paramount. You must demand full documentation that traces every raw material batch (including melt source and lot numbers for metals, or resin batch for composites) through every manufacturing process step, including subcontractor work, all the way to the finished part's unique serial number. This includes material certifications (CofCs), process certifications (e.g., NADCAP reports, heat treat charts), inspection records, and final release documents (e.g., FAA Form 8130-3 or EASA Form 1). This comprehensive paper trail is essential for regulatory compliance, anomaly investigation, and ensuring long-term airworthiness.
