AS9100D Certified: How Sealevel Delivers Trusted Quality for Aerospace and Defense

At Sealevel Systems, Inc., we take pride in building trustworthy rugged computing and I/O solutions that go above and beyond for our customers, especially those in mission-critical industries such as aerospace and defense. As an AS9100D-certified manufacturer, we meet one of the most rigorous, global quality management standards in these sectors, reinforcing our commitment to safety, reliability, and continuous improvement.

“AS9100D certification is a direct result of the operational discipline we apply every day to deliver dependable, high-quality solutions for our customers’ most demanding missions,” said Brandon Hansen, COO & CFO at Sealevel. “It reflects our commitment to earning the trust our customers place in us and to the rigorous standards we hold ourselves to. When our partners face tough challenges, they count on us to get it right.”

Our Approach to Quality

Sealevel’s approach to quality is rooted in a design-for-certification philosophy. From the initial concept, our teams evaluate the environmental, safety, and security requirements of each product, ensuring it will meet or exceed customer expectations across industries.

We design, produce, and test products in-house in Liberty, South Carolina, maintaining a near-constant feedback loop between engineers, manufacturing, and testing teams. This hands-on, collaborative process guarantees that Sealevel’s American-made products are rugged, reliable, and engineered to perform in extreme aerospace and defense environments.

Positioned to Tackle the Toughest Challenges

Achieving AS9100D certification is more than an accomplishment. It’s a commitment to our customers. It demonstrates that Sealevel operates with a disciplined quality management system aligned with internationally recognized standards, ensuring ongoing reliability, safety, and performance.

Sealevel is proud to serve aerospace and defense customers who rely on our rugged computing and I/O solutions for mission-critical operations. With AS9100D certification in place, Sealevel is positioned to help our partners tackle the toughest challenges—anywhere, anytime.

What is AS9100D Certification?

AS9100D is a rigorous framework designed for the unique demands of aerospace and defense. Sealevel’s AS9100D certification, awarded by TÜV SÜD America Inc., covers the design, manufacture, and sales of communications and I/O solutions for multiple computer platforms, as well as related software, technical support, and customer service. This certification—valid from May 9, 2025, to May 8, 2028—confirms that Sealevel’s quality management system has been audited and meets stringent international standards, technically equivalent to prEN 9100:2016 and JISQ 9100 - 2016.

Building on Sealevel's previously attained ISO 9001:2015 certification, AS9100D-enhanced requirements ensure that certified companies like Sealevel deliver rugged computing and I/O solutions that meet the highest levels of quality, reliability, and traceability. These enhancements provide key benefits for customers in aerospace and defense.

AS9100D adds requirements for:

• Enhanced product safety protocols
• Risk and project management procedures
• Configuration and work transfer control
• Counterfeit parts prevention
• Emphasis on ethical behavior and human factors

Here’s how each of these requirements helps Sealevel deliver exceptional value to our customers:

Enhanced Product Safety Protocols

AS9100D emphasizes product safety to ensure that devices and systems operate reliably without causing harm. For Sealevel’s customers in high-risk environments like aerospace and defense, enhanced safety protocols mean that our rugged computing and I/O solutions are designed with built-in safeguards to prevent failures, malfunctions, or unsafe conditions, protecting both people and critical missions. These safety practices are part of our broader commitment to product quality and help reinforce customer confidence throughout the supply chain.

Risk and Project Management Procedures

Risk management in AS9100D focuses on identifying, assessing, and mitigating potential issues throughout a product’s lifecycle, while project management ensures tasks are planned, tracked, and delivered as promised. For customers, this translates to reduced uncertainty, fewer delays, and confidence that Sealevel products will perform as expected. These practices reduce the risk of defects or non-conformance, helping customers meet tight schedules and avoid costly disruptions.

Configuration and Work Transfer Control

AS9100D requires rigorous control over configuration changes and the transfer of work between facilities or suppliers. This prevents unauthorized design modifications, maintains consistency, and reduces the risk of errors during production. These controls directly support procurement compliance by ensuring every unit meets its original specifications and is fully traceable, both of which are critical requirements in regulated industries like aerospace and defense.

Counterfeit Parts Prevention

In aerospace and defense, the use of counterfeit parts can lead to catastrophic failures. AS9100D requires strict procedures to prevent counterfeit components from entering the supply chain. This benefits customers by ensuring that every Sealevel product is built from genuine, verified parts, minimizing risks, supporting full traceability, and strengthening overall supply chain integrity.

Emphasis on Ethical Behavior and Human Factors

AS9100D introduces a focus on ethical behavior, safety culture, and human factors, recognizing that people and processes are critical to quality outcomes. These principles guide our teams across engineering, manufacturing, and support, reinforcing the trust customers place in Sealevel. Our focus on doing the right thing—for the customer, the product, and the mission—ensures long-term reliability, compliance, and customer satisfaction.

“Every requirement of AS9100D—from risk management to traceability to supplier control—is meant to ensure consistent quality and dependable results,” Hansen said. “But these aren’t just checkboxes at Sealevel. They’re the foundation of how we operate and why customers trust us to deliver in the most demanding environments.”
