Canyon State Inspection's aircraft inspection division offers nondestructive testing (NDT) to the commercial and corporate aviation industries. Operating as a FAA certified Limited Repair Station since 1986, CSI provides on-wing and in-house radiography (RT), eddy current (ET) both high and low frequency, ultrasonic (UT), dye penetrant (PT), magnetic particle (MT) and bond testing.

Services and experience include heavy maintenance modifications "C" & "D" check NDT for all Boeing Douglas and Lockheed aircraft.

Corporate aircraft experience includes heavy maintenance modifications, 1200 hour, 12000 hour and 12 year checks on all Beechcraft, Cessna (certified), Challenger, Gulfstream, Jetstar, and Learjet models.

Military aircraft experience includes service and maintenance checks of B1-B bombers, C-123, C-130 and C-47 cargo, F-14, F-15, F-16, F-4 fighters, space shuttle parts and 747 shuttle haulers.

Canyon State Inspection's equipment is portable and of the latest technologies. Our FAA repairmen have large amounts of experience with structures, landing gear and engine NDT.

CSI's aircraft division's success is based on four (4) key principals:

  1. Proper research of AD & service bulletins to understand the required task and inspections.
  2. Securing the proper equipment
  3. Securing the proper standards
  4. Assigning the proper personnel.


Ultrasonic Inspection

By using state of the art equipment, we are able to detect subsurface flaws and irregularities on various types of materials as well as thickness gauging when only one side of a surface is accessible. Ultrasonic testing, also referred to as UT, utilizes high frequency sound waves to achieve the required results. UT is considered one of the most versatile and sensitive method with the ability to be applied to components of all shapes, sizes, and thicknesses.

Magnetic Particle Inspection

Considered the most simplistic, cost effective and reliable methods of nondestructive testing, magnetic particle inspection (MPI) detects near surface defects of ferromagnetic components. MPI can be performed whether on site or in our laboratory, making this procedure highly effective for the aviation industry.

Liquid Penetrant Inspection

This method is utilized for both ferrous and non-ferrous materials to detect defects that outcrop at the surface of a component. Penetrant inspection is typically used when magnetic particle inspection cannot be performed. The process of this inspection includes spraying a component with penetrant and then developing it either with a red dye that is visible in natural light or a fluorescent dye that can only be seen in a black light. Like MPI Penetrant can be used both in the field or laboratory. It is a cost effective way to test large quantities of small parts efficiently and effectively.

Radiographic Inspection

Radiographic inspection is by far the most commonly known form of nondestructive testing. Radiography, also known as x-ray, has a wide variety of uses. It is a reliable and versatile method of inspection, allowing testing to be performed both on site and in the laboratory. By utilizing radiation our technicians are able to locate various defects in components.

Eddy Current Inspection

Eddy current inspection, also known as electromagnetic inspection, is a very powerful and accurate form of nondestructive testing. Used in both high and low frequencies, eddy current has the ability to find cracks, flaws and other forms of surface and near-surface damage in airframes and engines. Eddy current, like many other NDT methods, is utilized in both on site and laboratory situations
