In aerospace, safety is mission-critical. In an industry with rigorous engineering standards and strict FAA oversight, every component of an aircraft must be designed and developed with safety in mind.
Behind that disciplined safety process is non-destructive testing (NDT).
From commercial airliners to military aircraft to helicopters and private planes, NDT plays a vital role in detecting hidden flaws without damaging costly materials or components.
At American Testing Services (ATS), we offer non-destructive testing expertise to the aerospace industry, providing manufacturers, maintenance providers, and operators with reliable testing to maintain the highest level of safety standards.
Why is Non-Destructive Testing Essential in Aerospace?
Aircraft operate under extreme conditions. They undergo high altitudes, temperature fluctuations, pressurization, and repeated stress.
Over time, the repeated stress load cycle can lead to fatigue, corrosion, cracks, bonding failures, and composite delamination. Left undetected, even a small defect can have serious consequences.
Non-destructive aerospace testing provides a critical layer of assurance for manufacturers and maintenance providers. Using a range of non-destructive testing methods, technicians can detect and address flaws early, before they escalate into costly and potentially dangerous issues.
Supporting the Entire Aircraft Lifecycle
Because non-destructive testing is non-invasive and doesn’t alter the properties of the material being tested, it can be used throughout the aircraft’s entire lifecycle:
- Manufacturing: Ensures materials and components meet strict quality standards before selection and assembly
- Maintenance, Repair & Overhaul (MRO): Identifies wear and damage during routine inspections or after a minor accident, such as a bird strike
- In-Service Monitoring: Supports ongoing safety and performance over the life of the aircraft
In this way, non-destructive testing supports safety and compliance standards, but it also extends the service life of parts such as propeller blades, engines, landing gear, control panels, and wings. By detecting issues early, owners and operators can avoid unnecessary and expensive replacements.
Common NDT Methods Used in Aerospace
Different materials and components require different testing methods. Often, multiple techniques are used in tandem to gain a more complete picture of a product’s integrity.
Some of the most common NDT methods used in aerospace include:
Visual Inspection
As the most widely used NDT method, visual inspection is typically conducted on all components prior to performing additional non-destructive testing methods.
Ultrasonic Testing
Uses high-frequency sound waves to help detect internal imperfections and changes in material properties. It’s especially useful when verifying composite materials, a common material in modern aerospace and aviation.
Radiography
Uses X-rays to perform a volumetric assessment of raw materials, revealing hidden cracks, corrosion, and other flaws not visible to the naked eye.
Magnetic Particle Inspection
Uses magnetic particles to locate surface and near-surface discontinuities in ferromagnetic materials, such as steel landing gear components.
Liquid Penetrant Testing
Uses a fluorescent or visible liquid penetrant dye to highlight surface-breaking defects such as cracks, laps, seams, and porosity.
Eddy Current Testing
In addition to flaw detection, eddy current testing can provide precise measurements of material and coating thickness without causing any damage to the part. It’s used for research and development, manufacturing quality control, and in-service inspections of mission-critical components such as propeller blades.
