Specialized Services

At Duncan Aviation, we are uniquely positioned to offer a vast number of support services in-house in conjunction with any aircraft maintenance event. This is made possible by our comprehensive back shop capabilities.

We have invested millions of dollars in tools, equipment and resources so these specialized teams are prepared to quickly and efficiently provide the required aviation maintenance services, with greater control over quality, pricing and downtime.

Calibration Services

Duncan Aviation’s Calibration Services use NIST traceable standards to calibrate measuring & test equipment (M&TE). Bring your tools with you the next time your aircraft is serviced at one of our full-service maintenance facilities. They will be returned to you when you are ready to leave, properly calibrated and ready for use.

Can’t be long without your tools? Send them to us and we’ll have them back to you in fewer than five days.

The Duncan Aviation NDT team can test nearly every surface of an aircraft and a near limitless list of materials. They are called to locate cracks in parts before they fail, evaluate areas of corrosion, as well as determine remaining thickness on materials. Following a strict, established protocol, every piece of equipment is calibrated to the exact test and material surface. Specialized probes increase their capabilities of accurately testing any size or shaped surface whether on the exterior of the aircraft or hidden inside.
