Our expert aircraft NDT services help detect hidden defects, prevent failures, and extend the life of critical aircraft components, ensuring airworthiness and operational efficiency.
Magnetic Particle Testing (MT) is an NDT inspection method used to detect surface and near-surface cracks, fractures, and discontinuities in ferromagnetic materials such as steel and iron. This method applies a magnetic field and introduces iron particles to reveal defects in aircraft components like landing gear, engine mounts, and structural components. MT is widely used in aircraft maintenance and aerospace quality control to ensure structural integrity.
Visual Testing (VT) is the most common non-destructive inspection technique, involving a trained NDT technicianexamining components for visible defects, cracks, corrosion, wear, or damage. This method is often the first step in aircraft inspections and is used in conjunction with advanced NDT techniques such as eddy current testing (ET) and ultrasonic testing (UT) for deeper analysis.
Borescope Inspections use high-resolution cameras and flexible fiber-optic scopes to inspect hard-to-reach areaswithin aircraft engines, turbine blades, fuel systems, and hydraulic components. This remote visual inspection (RVI) technique allows technicians to detect internal corrosion, cracks, foreign object debris (FOD), and other defects without disassembly, minimizing aircraft downtime.
Radiographic Testing (RT) is an advanced NDT method that uses X-rays or gamma rays to detect internal defects, hidden cracks, and voids within aircraft structures, welds, and composite materials. RT provides a detailed view of subsurface defects in aluminum, titanium, and composite airframe components, ensuring airworthiness and compliance with FAA and aerospace industry standards.
Film Radiography is a traditional non-destructive inspection method using X-ray film to capture high-resolution images of aircraft structures and components. This method is widely used in aerospace NDT to inspect weld integrity, metal fatigue, composite delamination, and hidden corrosion. Although digital radiography is gaining popularity, film radiography remains a gold standard for detailed aircraft inspections.
Liquid Penetrant Testing (PT), or Dye Penetrant Inspection (DPI), is a highly effective method for detecting surface cracks, pinholes, and defects in non-porous aircraft components, including aluminum, titanium, and composite materials. This technique uses fluorescent or visible dye that seeps into flaws, making them visible under ultraviolet (UV) light or white light. PT is essential for aircraft structural integrity checks and maintenance inspections.
Eddy Current Testing (ET) is a highly sensitive electromagnetic NDT technique used for detecting cracks, corrosion, and material thinning in aircraft fuselage skins, wing structures, and fastener holes. ET is widely used in aviation maintenance, aerospace manufacturing, and FAA-certified inspections due to its ability to detect fatigue cracks and hidden defects in aluminum, titanium, and other conductive materials without requiring surface preparation.
Ultrasonic Testing (UT) is a high-frequency sound wave inspection method used to detect internal defects, delaminations, and thickness variations in aircraft structures, composite materials, and metallic components. UT plays a crucial role in aircraft MRO (Maintenance, Repair, and Overhaul), helping technicians locate subsurface defects, weld discontinuities, and material degradation to ensure FAA compliance and aerospace safety.
Ultrasonic Thickness Testing (UTT) is a specialized NDT method designed to measure material thickness and detect corrosion, erosion, and thinning in aircraft structures. UTT is widely used in aircraft skin inspections, fuel tank integrity checks, and engine component evaluations. This FAA-approved inspection technique ensures that aircraft meet strict safety and operational standards while reducing the risk of unexpected structural failures.
Our aircraft NDT technicians are certified to Level II and Level III in accordance with ASNT’s SNT-TC-1A and CP-189 standards, ensuring industry-leading expertise and compliance.
