Ryan Winkler, NDT Technician II, now provides NDT services for Duncan Aviation's mobile NDT services team. The team has technicians based in Michigan, Nebraska, and Utah, who can travel to meet aircraft operator needs.

Duncan Aviation has expanded its Mobile Nondestructive Testing (NDT) services, providing aircraft operators across the country with convenient, on-site access to its industry-leading inspection expertise.

The company's Mobile NDT program supports customers who prefer to complete smaller, in-house inspections without relocating their aircraft. With teams operating from Lincoln, Nebraska; Battle Creek, Michigan; and Provo, Utah, Duncan Aviation offers nationwide coverage and flexible scheduling with three shifts and seven-day availability.

Each mobile team is fully equipped to perform a wide range of inspections. All technicians are full-time NDT Level 2 or 3 in accordance with NAS410, ensuring every inspection meets the highest safety and quality standards.

Duncan Aviation holds NDT specific authorizations from Dassault, Textron, Honeywell, Rolls-Royce, and Pratt & Whitney. These authorizations demonstrate Duncan Aviation's ability to meet manufacturer-specific requirements and maintain consistency across all testing environments.

The Mobile NDT program allows Duncan Aviation to deliver the same high-quality testing performed in its main facilities directly at customers' locations. Services include eddy current, fluorescent penetrant, ultrasonic, magnetic particle, and optical prism inspections for a wide variety of aircraft, engines and components.
