NDT Simulator and Hands-On Practical Training in Spokane, Washington

Spokane’s industrial identity is written in aluminium and airframes. In Spokane Valley, the Trentwood rolling mill, built by the federal government in 1942 and run by Kaiser Aluminum since 1946, is described as the largest aerospace aluminium plate and sheet operation in North America, producing heat-treated plate for wing skins and fuselage structures. West of the city, Fairchild Air Force Base flies a large fleet of KC-135 Stratotankers, and next door in Airway Heights a cluster of aerospace fabricators and composite specialists has grown, backed by a federally designated tech hub focused on advanced aerospace materials. Every one of those activities depends on inspectors who can find a lamination in plate, a crack at a fastener hole, or corrosion hidden under a lap joint. Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience, and Practical NDT brings that practice to the Inland Northwest. It is an immersive, game-like 3D environment you open in a browser or the app. You choose the method, set up the probe, scan the part, call what you see, and get scored feedback instantly. For Spokane, that means far more repetitions on eddy current, ultrasonic and surface inspection of aerospace-grade material, without tying up reference standards, test pieces or real aircraft.

Why Hands-On NDT Practice Matters in Spokane’s Aerospace and Metals Economy

Aerospace inspection is unforgiving in a particular way. The critical defects are small: a fatigue crack a fraction of an inch long at a fastener hole, a thin band of corrosion under a skin splice, an inclusion in a thick plate that becomes a crack initiation site after years of load cycles. Finding them reliably takes technique discipline, not luck. Eddy current inspection of bolt holes and surfaces depends on correct frequency, probe selection, calibration on reference standards and a steady scan; ultrasonic inspection of plate and forgings depends on proper sensitivity, coverage and the ability to tell a real reflector from grain noise or a geometric echo. Those skills fade quickly without use, and in a region where a technician may move between a rolling mill, a machine shop, an airline or military maintenance, and a fabrication job, the method mix changes often. At the same time, the real resources for practice are scarce. Reference standards with EDM notches are expensive and needed for production. Airframe sections with known cracks are rare and closely held. Aircraft time is not available for training. And nobody wants a new technician learning to set up a bolt-hole probe on a tanker in the middle of a scheduled inspection. Practical NDT gives Spokane technicians a place to practise those decisions over and over, including rare defects they might go years without seeing on real hardware, so that when the real part is in front of them, the technique is already reliable.

Methods You Can Practise: Eddy Current, UT and Surface Methods on Aerospace Parts

Practical NDT includes twelve methods. Surface methods are penetrant testing (PT), magnetic particle testing (MT) and visual testing (VT). Volumetric methods are contact ultrasonic testing (UT), phased array ultrasonic testing (PAUT), time-of-flight diffraction (TOFD) and radiographic testing (RT). Electromagnetic methods are eddy current testing (ET) and magnetic flux leakage (MFL). Specialist methods are long-range ultrasonic testing (LRUT), internal rotary inspection system (IRIS) ultrasonic testing, and positive material identification (PMI). For Spokane’s aerospace and metals base, ET, UT, PAUT and PT carry most of the weight. Eddy current scenarios cover surface crack detection on airframe skins and fittings, fastener-hole inspection, and the setup decisions that make or break an ET inspection: frequency, gain, phase rotation and calibration on a reference standard. Ultrasonic scenarios cover calibration, thickness measurement, straight-beam inspection for laminations and inclusions in plate and forgings, and angle-beam inspection of welds and components. Phased array scenarios let technicians build and interpret sectorial and linear scans, a method increasingly used on thick aerospace plate and complex parts. PT scenarios, central for non-ferrous aluminium and titanium, cover surface preparation, dwell, removal, developer and interpretation. VT covers corrosion, damage and workmanship checks. MT, RT, TOFD and PMI round out the set for technicians who also work in steel fabrication, power or industrial maintenance around the region.

The Environments That Fit Spokane Work

Practical NDT is built around five virtual workplaces. The Aircraft Hangar, with 54 jobs, is the obvious home for Spokane: airframe and component inspection scenarios using ET, UT, PT and VT, covering the kind of work performed during military and civil maintenance, including surface and bolt-hole crack detection, corrosion assessment and component checks. For technicians at or around Fairchild, the Spokane International Airport, or the maintenance and repair shops in the region, it is the most direct preparation. The NDT Lab, with 52 jobs, is the bench: reference blocks, calibration and flawed specimens of plate, forgings and bar, closely aligned with the discipline of plate and product inspection in a metals mill. The Welding Workshop, also with 52 jobs, covers weld coupons and fabrication joints and is useful for technicians supporting structural and pressure fabrication in the Inland Northwest. The Oil & Gas Site, with 73 jobs, and the Storage Tank environment offer process-plant piping, corrosion, tube inspection, guided-wave screening, alloy verification, UT shell surveys and MFL floor screening, relevant to industrial plants, fuel storage and utility systems in eastern Washington and northern Idaho. Thirty-three guided lessons organise the learning path across all five environments.

Built for Every Skill Level, from Trainee to Level III

Spokane’s inspection workforce draws from many directions. New trainees come from aviation maintenance technician programs, manufacturing and machining courses, the military and the trades. For them, Practical NDT’s guided lessons explain how each method works and why each step matters, then build up to realistic inspections with immediate, explained feedback. Aviation maintenance students in particular benefit from understanding eddy current and ultrasonic setup early, since those are the methods most commonly used in structural inspection programs. Working technicians use the simulator to stay current. A technician who has spent months on plate ultrasonics might move to an eddy current role; a military or civil maintainer might only perform a particular inspection a few times a year. Practical NDT lets them refresh the setup and technique, and drill defects that are rare on real hardware but critical to catch, such as a small crack at a fastener hole or corrosion at a lap joint. Level IIIs and quality leads get the tools to build scenario sets that mirror their inspection requirements, assign them to a team, and compare results on the same scale for everyone. In aerospace, where inspection programs and quality systems expect evidence of proficiency, that objective view helps a lead decide who is ready, who needs more supervised time on real standards, and where the team’s coverage gaps lie.

How It Complements Formal ASNT Training and the Practical Exam

Practical NDT is a skills-practice and readiness tool. It is not a certification, it does not grant a level, and it does not replace the practical examination on real specimens required under ASNT SNT-TC-1A and the employer’s written practice. Under SNT-TC-1A, the written practice specifies training and experience hours and the general, specific and practical examinations, and the practical is performed with real equipment on real parts. In aerospace, employers and customers may also require qualification to other schemes, such as NAS 410 for aerospace NDT personnel, and military maintenance organisations follow their own qualification rules; those remain the employer’s requirements and are mentioned here only as market context. What Practical NDT provides is realistic NDT practical exam preparation and ongoing proficiency practice, so that when a technician faces a real practical exam or a real inspection, they are applying a skill that has been rehearsed many times. It sits alongside Atlantis’s classroom and hands-on NDT training programs, which prepare technicians for employer certification under SNT-TC-1A. The scenario library was designed by Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT, who also leads Atlantis training. Use the simulator for volume and variety; save real standards, real aircraft time and Level III supervision for what only real hardware can teach.

Spokane’s Industrial Geography: Trentwood, Fairchild, Airway Heights and the Rivers

The Spokane region’s inspection demand is anchored in a few clear places. In Spokane Valley, the Trentwood aluminium mill produces heat-treated plate and sheet for aerospace and other markets and has seen repeated investment over the years; plate for aircraft structure is subject to demanding ultrasonic inspection requirements, and the mill anchors a surrounding cluster of precision machine shops, fabricators and suppliers. To the west, Fairchild Air Force Base hosts the 92nd Air Refueling Wing and a large KC-135 fleet, and aircraft of that age depend on structural inspection programs that rely heavily on eddy current, ultrasonic and visual methods. In Airway Heights, aerospace fabricators working in high-temperature sheet metal, composites and assemblies have established themselves, and a regional consortium was designated a federal Tech Hub for advanced aerospace materials, with a focus on thermoplastic composites. Spokane International Airport and Felts Field support civil aviation and maintenance training. The region’s rivers matter too: hydroelectric dams on the Spokane River, and larger dams on the Columbia to the west, involve penstocks, gates, turbines and structural steel that require inspection. Add rail, food processing, and industrial plants across eastern Washington and northern Idaho, and the mix of work is broad. Practical NDT maps to it: the Aircraft Hangar for aviation, the NDT Lab for plate and product inspection, the Welding Workshop for fabrication, and the Oil & Gas Site and Storage Tank for plant and utility work.

Radiation Safety and Regulatory Context in Washington

Washington is an NRC Agreement State. Industrial radiography licensing, radioactive materials licensing and X-ray registration are handled by the Washington State Department of Health Office of Radiation Protection, which has a field office in Spokane as well as offices in Tumwater and Richland, and its rules include specific requirements for industrial radiography licensees. Radiographers working in the Spokane area need training, qualification, dosimetry and controlled areas, and every exposure carries time, dose and cost. Aerospace radiography adds its own challenges: thin sections, small features and film or digital images that must be read carefully. Interpretation is a perfect candidate for simulation. In Practical NDT, a trainee can practise RT scenarios on welds and components: exposure geometry, source-to-film distance, image quality indicators, density checks, and interpreting porosity, inclusions, incomplete penetration, lack of fusion and cracks. The simulator is not radiation safety training or qualification, and it does not make anyone a radiographer or assistant. It does give a Spokane trainee a foundation in image quality and defect recognition before they work under a licensed radiographer. Most Spokane aerospace inspection relies on ET, UT and PT rather than radiography, and the same logic applies there: learn setup and interpretation on screen, then apply it under supervision on real parts.

Bringing Practical NDT to Your Spokane Team

Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience, and it fits naturally into Spokane aerospace shops, metals producers’ suppliers, inspection companies, maintenance organisations and training programs. It starts with a live demo where we walk through the Aircraft Hangar and NDT Lab scenarios most relevant to aerospace and plate inspection, and the Welding Workshop, Oil & Gas Site and Storage Tank scenarios for fabrication and plant work. We then agree which methods matter most, typically ET, UT, PAUT and PT for aerospace, set up accounts for trainees, technicians and leads, and give your Level III tools to build scenario sets and review results. Practical NDT runs in a browser or the app, so there is no hardware to install and it can be used in a hangar office, a classroom or at home. Pricing is quote on request; the platform is affordable, accessible and fully customisable. To see it, request a Practical NDT demo for Spokane. Aviation training programs can ask about classroom and program use, and teams planning certification courses can pair the simulator with Atlantis NDT training.

Frequently Asked Questions

Does Practical NDT replace the practical certification exam?

No. It is a practice and readiness tool. Certification under ASNT SNT-TC-1A and your employer’s written practice still requires training, experience and general, specific and practical examinations, with the practical performed on real specimens. Any aerospace or military qualification requirements also still apply. Practical NDT helps you prepare; it does not certify you.

What experience level is it for?

All levels. New trainees follow 33 guided lessons. Working technicians refresh methods and drill rare defects. Level IIIs and quality leads build scenario sets, benchmark teams and identify coverage gaps.

Is there an eddy current simulator for aircraft inspection?

Yes. The Aircraft Hangar includes eddy current scenarios for surface and fastener-hole crack detection, with setup decisions such as frequency, gain, phase and calibration on reference standards, alongside UT, PT and VT scenarios on airframe structure and components.

Does it help with plate and product ultrasonic inspection?

Yes. The NDT Lab includes straight-beam and angle-beam UT and phased array scenarios on plate, forgings and bar, with calibration on reference blocks and indication evaluation against noise and geometry.
