Best Aerospace NDT Inspection Companies

Aerospace NDT inspection is among the most regulated and technically demanding forms of non-destructive testing, governed by NAS 410, customer-specific written practices, and Nadcap accreditation requirements. These companies perform inspection of flight-critical metallic and composite structures, engine components, rotorcraft hardware, and defense assemblies to the exacting detection thresholds required by Boeing, Airbus, Lockheed Martin, and their supply chains. Nadcap accreditation — administered by the Performance Review Institute — is the aerospace industry's third-party verification that an NDT lab's procedures, equipment, and personnel meet prime contractor requirements. Use this directory to find accredited aerospace NDT providers with the specific method scope your parts require.

Why these suppliers?

  • Nadcap-accredited NDT companies have successfully completed PRI audits validating their procedures, equipment calibration, personnel certifications, and quality records — reducing your qualification burden compared to qualifying a non-accredited supplier.
  • Aerospace NDT providers listed here have documented experience with aerospace alloys (titanium, Inconel, aluminum, composites) and the specific discontinuity detection requirements of flight hardware.
  • Our directory includes method-level detail so you can identify companies with scope in the specific NDT method (RT, PAUT, UT, MT, PT, ET) your engineering drawing or purchase order requires.

Frequently Asked Questions

What is Nadcap NDT accreditation and why does it matter?
Nadcap (National Aerospace and Defense Contractors Accreditation Program) is an industry-managed accreditation program administered by the Performance Review Institute (PRI). Nadcap NDT accreditation means an independent audit has verified that the company's NDT procedures, personnel certifications, equipment calibration, and quality documentation meet the requirements of the applicable aerospace NDT standards (typically NAS 410 and customer-specific requirements). Most aerospace prime contractors require their NDT suppliers to hold Nadcap accreditation to reduce the burden of individual customer audits.
What NDT methods require Nadcap accreditation for aerospace?
Nadcap accreditation is available and typically required for: Radiographic Testing (RT), Ultrasonic Testing (UT), Magnetic Particle Testing (MT), Liquid Penetrant Testing (PT), Eddy Current Testing (ET), and emerging methods like Phased Array UT. The accreditation is method-specific — a company may hold Nadcap for PT and MT but not RT. Always confirm the company's current Nadcap scope matches the methods specified on your engineering drawing or quality plan.
How do I verify a company's Nadcap accreditation is current?
Nadcap accreditations are time-limited and must be renewed periodically. Verify current accreditation status in the PRI Qualified Manufacturers Listing (QML) database at pri-network.com/suppliers. The QML lists active accreditations by company name, location, commodity, and scope. Do not rely solely on a certificate provided by the supplier — always cross-check against the live PRI database, as accreditations can lapse between renewals.
