Blog Post: non-destrcutive testing in aerospace

Here are the four critical pillars someone in the aerospace sector should look for in an NDT partner.

1 . Nadcap Accreditation

Accreditation is the baseline, but the length and quality of that accreditation tell a deeper story. A provider that has achieved a 2-year Nadcap Merit certification, as ATH NDT recently did, demonstrates a consistent history of excellence and a robust quality management system that requires less frequent oversight because it is inherently reliable.

2 . High-Efficiency Technology: The Electrostatic Advantage

In modern aerospace manufacturing, volume and precision must coexist. Traditional dip-and-drain penetrant methods are often slow and result in excessive chemical waste.

An ideal NDT partner utilises Electrostatic Penetrant Lines. This technology uses charged particles to ensure 360-degree coverage of complex geometries, common in aerospace components, while reducing “drag-out” and chemical consumption. For the manufacturer, this means:

• Superior Flaw Detection: More consistent application leads to clearer indications of surface-breaking defects.
• Reduced Bottlenecks: Faster processing times mean your components move through inspection and back into the assembly line quicker.
• Environmental Compliance: Lower chemical usage supports the industry’s growing push toward sustainable manufacturing.

3 . In-House Level 3 Consultancy

Many NDT shops are “operators only,” meaning they can follow a procedure but cannot write or validate one. In aerospace, you need access to Level 3 technicians who can oversee the entire NDT department, create bespoke procedures, and provide training.

A partner that offers “Outside Agency” services can help your business set up its own in-house NDT department, ensuring you remain compliant with NANDTB (National Aerospace NDT Board) requirements without the overhead of a full-time staff Level 3.

4 . Continuity and Stability

The aerospace supply chain has been rocked by staff shortages and shifting regulations. When choosing a partner, look for longevity. How long have they been working with their partners? For instance, at ATH NDT, we have maintained partnerships with aerospace firms for over a decade. This continuity means your partner understands your specific parts, your history, and your unique quality requirements, preventing the “knowledge gap” that often occurs with high staff turnover.
