Why Heartland Precision Fasteners Are Trusted in Aerospace Applications

Fasteners employed in aircraft and spacecraft play a decisive role in maintaining the integrity of structures and countless onboard systems, with a single one out of place having the potential to cause heightened vibration, premature fatigue, or complete failure. As such, aerospace fasteners have to be made by manufacturers who follow very exacting regulatory standards, with Heartland Precision Fasteners being one such entity capable of consistently meeting these demands. Read on as we cover some of the oversight that goes into the production of aerospace fasteners and contextualize how some of Heartland Precision Fasteners products have earned their way into this sector.

The Standards Set for Aerospace Fasteners

Before any fastener can be approved for use in aircraft, manufacturers must align with a series of industry standards and regulatory expectations that begin with basic quality management requirements and move toward highly specialized aerospace certifications and approvals:

• ISO 9001: This International Organization for Standardization (ISO) standard is the foundation for all manufacturers, governing documentation practices, corrective actions, and process controls for both consistency and traceability.
• AS9100: Building on ISO 9001, the International Aerospace Quality Group (IAQG) developed AS9100 to address the unique needs of the aviation, space, and defense industries. For fastener manufacturers, certification requires demonstrating robust quality management systems with emphasis on product safety, risk management, configuration control, and full traceability to create products with consistent dimensions, materials, and documentation.
• NADCAP Audit: Administered by the Performance Review Institute, National Aerospace and Defense Contractors Accreditation Program (NADCAP) audits certify that specialized manufacturing techniques like heat treatment, plating and coating, and non-destructive testing are carried out to globally recognized aerospace benchmarks.
• DFARS and Related Export Controls: For United States defense and government contracts, compliance with DFARS (Defense Federal Acquisition Regulation Supplement) in sourcing practices, traceability, and material origin is mandatory. Additionally, fasteners used in defense applications may also fall under ITAR (International Traffic in Arms Regulations) or EAR (Export Administration Regulations) to control international transfers.
• FAA PMA Approval: For replacement parts not produced by the Original Equipment Manufacturer (OEM), Parts Manufacturer Approval (PMA) authorization has to be pursued. In this process, the FAA evaluates the item’s design and performance through either its identicality to an OEM component or independent testing.

What Manufacturers Must Demonstrate

With the regulatory roadmap established, manufacturers need to follow all guidelines for:

1- Certification and Accreditation: ISO 9001, AS9100, and any required NADCAP certifications collectively demonstrate a functioning quality management system, aerospace-specific safeguards, and approved special procedures. For PMA part production, this also may include OEM approvals to validate that an organization has been directly vetted by aircraft producers.

2- Traceability: Every aerospace fastener must be fully traceable back to its source materials and production batch in the event that a defect is identified. As such, manufacturers are expected to provide:

• Material test reports and certificates of conformance
• Lot and serial number tracking for every production run
• Detailed inspection records and quality assurance documentatio

3- Proven Performance: Evidence that aerospace fasteners perform reliably is imperative for a manufacturer to present, involving in-depth:

• Qualification Testing: Aerospace fasteners are subjected to tensile, shear, fatigue, and vibration testing to verify how they hold up under flight-like loads.
• Environmental Testing: Corrosion resistance, thermal cycling, and salt-spray tests confirm resilience in the conditions aircraft encounter.
• Dimensional Verification: Fastener tolerances need to fall within a few ten-thousandths of an inch for proper fit and performance.
• Supplier Performance Metrics: Manufacturers are evaluated on defect rates, statistical process control data, and long-term reliability records across multiple production runs. Moreover, companies maintain their approval status through continuous oversight of these factors.
