Inspection of advanced materials is difficult since flaws will not appear as they do in traditional metallic parts. Delamination, porosity, impact damage or bond problems can occur in composite materials, while internal voids, lack of fusion and surface finish within channels can happen in additive manufacturing. Inspection systems must adapt to these material-specific risks.

The growth forecast also points to this shift. Research and Markets says aerospace and defense NDT growth is being supported by automated and robotic NDT, real-time data analytics, portable devices for field inspection and specialized NDT needs created by additive manufacturing. 

This is especially important for aerospace suppliers moving additive manufacturing from prototype to production. A 3D-printed bracket, heat exchanger or engine-related part may have internal features that cannot be checked through ordinary visual inspection. Computed tomography, advanced ultrasonics and digital radiography can become necessary to verify build quality.

Composite inspection is also gaining attention. The 2026 computer vision study on aerospace SiC/SiC composites reflects the difficulty of assessing advanced ceramic matrix composites through X-ray tomography. The researchers emphasized the need for traceable defect decisions because expert visual review can lack consistent documentation. 

This creates a stronger role for inspection system providers. Customers need help choosing the right technique, validating inspection procedures and defining acceptance criteria. A system sale alone may not be enough when the material, geometry and defect mode are new.

Supply chain quality is another issue. Aerospace primes increasingly rely on specialized suppliers for machined, composite and additively manufactured parts. Inspection data must move across the supply chain in a usable format so that customers can verify quality without repeating every test.

Portable inspection tools will remain important for field use, but laboratory-grade systems will also grow where parts require deeper analysis. The market will likely split between high-throughput production inspection and advanced defect characterization.

The next phase of aerospace NDT will favor providers that understand material science as well as inspection technology. Buyers need systems that can keep pace with the changing parts entering aircraft and spacecraft programs.

Aerospace non-destructive testing and inspection systems are becoming more specialized as materials evolve. Their value will be measured by whether they help aerospace companies qualify advanced parts without weakening safety, documentation or production efficiency.

Aerospace non-destructive testing and inspection systems are being reshaped by automation and AI as manufacturers and maintenance providers look for faster inspection cycles. The goal is not to remove expert inspectors from the process. It is to help them handle larger data volumes, reduce manual variation and make defect evaluation more consistent. Aerospace inspection is becoming more data-intensive. Digital radiography, computed tomography, phased-array ultrasonics and high-resolution visual inspection can generate large datasets. These outputs can improve inspection depth, but they also create a review burden for skilled personnel. Research in aerospace NDT describes the industry as rapidly incorporating robotics, AI, machine learning and advanced analytics into inspection processes. These technologies are being used to improve accuracy, efficiency and safety in aircraft maintenance and inspection workflows.  Automation is of particular value in cases when inspections are repetitive, hard to reach or challenging. Robotized scanning machines may move along specified paths on aircraft structures. Automated ultrasonic inspection systems may control the movement of the probe to inspect complex parts. Vision systems may filter out images for potential defect existence prior to human evaluation. AI is also being applied in defect detection in the form of an interpretable computer vision system that was introduced in 2026 for X-ray computed tomography of aerospace SiC/SiC composites. This paper demonstrates the importance of transparency in the use of AI in aerospace quality decisions. This aspect is crucial. Buyers of aerospace equipment will never accept black box automation without proof of its reliability for inspection. Tools with AI technology should provide information on what is reliable and uncertain, as well as correlation with known defect types. Drone and robotic inspection are also moving forward. A 2026 paper demonstrated autonomous contact-based ultrasonic NDT using a commercial multirotor in an unstructured industrial environment. The study shows how autonomous systems may eventually support inspection in confined or hazardous areas.  For system providers, the opportunity lies in combining automation with auditability. A useful inspection system should capture data, flag anomalies and preserve a clear record of how decisions were made. This is important for manufacturers, airlines and defense customers that must defend inspection outcomes during audits. The challenge is integration. Automated systems must fit existing quality procedures, training programs and certification expectations. A technology that improves detection but disrupts documentation may struggle to scale. The next phase of aerospace inspection will likely reward providers that offer explainable AI, controlled robotics and practical workflow integration. Speed matters, but trust matters more. Aerospace non-destructive testing and inspection systems are becoming decision-support platforms. Their strongest value will come from helping inspectors work faster while maintaining the traceability and judgment that aerospace quality demands. ...Read more
Aerospace non-destructive testing and inspection systems are gaining stronger relevance as aircraft manufacturers, defense programs and maintenance providers face tighter safety expectations. The sector depends on inspection methods that can find internal or surface-level defects without damaging high-value parts, which makes NDT central to both production quality and in-service reliability. The market outlook reflects this role. The global non-destructive testing market in aerospace and defense was valued at USD 3.33 billion in 2025 and is projected to reach USD 5.25 billion by 2032, with a CAGR of about 6.8 percent. Maintenance, repair and overhaul accounted for the largest application share in 2025. This growth is being shaped by fleet age, aircraft utilization and tighter inspection requirements across safety-critical components. An aircraft part may appear sound externally while containing cracks, voids, corrosion or bond defects that can affect long-term performance. NDT systems help operators identify these issues before they become failures. The principal methods are still very application-oriented. For example, ultrasonic testing can be used to find flaws and thickness variations. The eddy current testing technique is applied extensively for detecting surface and subsurface flaws in conductive materials. Radiographic testing will be able to provide information about the internal structure of the product when volume testing is required. In 2025, ultrasonic testing was leading the aerospace and defense non-destructive testing market by technique with a 31.5 percent share. It is due to a broader application of the method on aircraft structures, engines, and in other areas requiring the detection of internal flaws. Aerospace manufacturers require non-destructive testing to guarantee first-time quality. Rejected components can slow down the assembly process and lead to costly repair work. Inspection technologies that allow receiving consistent results and providing integration into production records may help suppliers to have more control over the process. However, MRO service providers experience different requirements. They need efficient inspection solutions that will ensure a fast testing process without compromising safety. Portable systems, advanced probes and digital reporting can help technicians inspect aircraft more efficiently while preserving traceability. Certification and personnel qualification remain central. The FAA’s Advisory Circular 65-31B provides recommendations for experience, training, qualification, examination and certification of NDI personnel involved in inspecting aircraft, engines, propellers and other aviation components. The next phase of aerospace NDT will likely favor systems that combine proven inspection physics with better data handling. Customers need accurate detection, but they also need results that can be stored, reviewed and linked to quality decisions. Aerospace non-destructive testing and Inspection technology is increasingly being seen as part of the life cycle assurance process. The effectiveness of such technologies will depend on their ability to assist manufacturers and MRO facilities in maintaining safety without increasing uncertainty. ...Read more
The way aircraft operators in Europe evaluate MRO providers is beginning to change. While technical approvals remain a key part of the procurement process, buyers are also considering how providers deliver support beyond a single maintenance visit. Consistency, reliability and the ability to maintain an ongoing service relationship are becoming more important in supplier evaluations. Maintenance responsibilities do not end once an aircraft leaves the hangar. Scheduled inspections, unplanned repairs and component replacements can arise throughout an aircraft's service life. For airlines and other fleet operators, working with an MRO provider that understands previous maintenance work and established procedures can make future planning more straightforward while reducing administrative effort. These changing priorities are influencing how procurement teams assess potential service providers. Cost continues to play an important role, but buyers are also considering how providers manage day-to-day coordination after maintenance agreements are in place. Clear communication, dependable scheduling and the ability to respond effectively when follow-up work is required are becoming increasingly important when comparing providers with similar technical capabilities. The growing demands of aircraft maintenance are also encouraging closer coordination between operators and MRO providers. Keeping aircraft available for service depends on maintenance activities progressing according to plan. Even small changes to maintenance schedules can affect broader fleet planning, making regular communication an essential part of keeping maintenance programs on track. An established relationship with an MRO provider can become especially valuable when maintenance plans change unexpectedly. Operators that already have an ongoing partnership may find it easier to schedule additional inspections or revise planned maintenance without restarting the procurement process. A provider that is already familiar with an aircraft's maintenance history can also prepare more efficiently for future visits. These practical realities are also shaping procurement strategies. Instead of viewing maintenance as a series of standalone projects, many buyers are placing greater emphasis on providers that can support recurring maintenance needs over the long term. That approach can help reduce uncertainty when planning future maintenance work, particularly for operators managing large fleets or aircraft with different maintenance requirements. Communication is becoming another important factor in supplier relationships. Buyers increasingly expect timely updates when maintenance schedules change or additional repairs are required. Receiving that information early gives operators more time to adjust fleet schedules and make informed decisions about aircraft deployment. It also provides greater clarity throughout the maintenance process rather than forcing customers to respond to last-minute changes. MRO providers are responding by placing greater emphasis on long-term customer relationships. Delivering consistent service across repeated maintenance visit calls for careful planning and reliable execution. At the same time, providers must balance the needs of existing customers with new maintenance demand while maintaining consistent service standards. Digital maintenance systems can make it easier to share maintenance records and planning information between operators and service providers. Even so, technology supports the relationship rather than replacing it. Buyers continue to judge MRO providers by how consistently they deliver maintenance work, communicate throughout the process and support aircraft over time. For organizations procuring MRO services in Europe, supplier evaluations are becoming broader than technical capability alone. Maintenance expertise remains the foundation of every engagement, but responsiveness, communication and dependable long-term support are carrying greater weight in procurement decisions. As aircraft remain in service for longer periods, the strength of the relationship between operators and MRO providers is becoming an increasingly important part of long-term maintenance planning. ...Read more
For many aircraft operators across Europe, finding an available maintenance slot is only part of the challenge. Having enough skilled technicians to carry out the work has become an equally pressing concern as maintenance demand continues to grow. Recruiting new staff is only one part of the equation. Keeping experienced personnel and preserving specialized expertise have become just as important. Years of practical experience underpin much of the work carried out by MRO technicians. Tasks such as aircraft inspections, component repairs and certification require technical judgment that cannot be replaced quickly. When experienced technicians retire or move on, maintenance providers face the difficult task of passing that knowledge to the next generation without disrupting customer schedules. Airlines are experiencing the impact on day-to-day maintenance planning. When skilled technicians are in short supply, maintenance booking windows can become longer, turnaround times may increase and responding to unexpected repair requirements becomes more difficult. That often means operators must arrange heavy maintenance visits much earlier, particularly for aircraft that need specialized expertise or complex inspections. European MRO providers are responding by placing greater attention on workforce planning rather than treating recruitment as an occasional activity. Training programs have become an important part of long-term capacity planning because newly hired technicians require time before they can independently perform certified maintenance tasks. This creates a gradual transition rather than an immediate increase in available labor. The changing makeup of aircraft fleets is giving maintenance teams more to manage. Technicians are expected to stay current on established aircraft while learning the requirements of newer models entering service. That creates an ongoing need for training and updated maintenance procedures without reducing the demands of everyday maintenance work. Maintaining service quality also depends on retaining experienced people. Providers with high employee turnover may struggle to keep inspection practices consistent across different teams. Standardized processes help, but they cannot replace the hands-on experience technicians develop over years of working on aircraft. These workforce considerations are also becoming part of the buying process. Technical approvals and facility capabilities remain important when evaluating MRO providers, but buyers are increasingly looking at how companies build and retain skilled teams. Providers that invest in technician development and knowledge transfer may be better equipped to support long-term maintenance programs than those that depend heavily on short-term hiring. Workforce availability also shapes expansion plans. Increasing maintenance capacity involves more than building new facilities or adding hangar space. Repair centers still need qualified technicians to carry out inspections, certify repairs and complete maintenance documentation. As a result, expansion often depends as much on access to skilled personnel as it does on investment in infrastructure. Digital tools may help technicians manage maintenance records or coordinate repair activities more efficiently, but they do not eliminate the need for experienced personnel. Aircraft maintenance continues to depend on technical judgment, regulatory compliance and careful inspection work that requires skilled professionals throughout the maintenance process. For organizations purchasing MRO services in Europe, workforce capability is becoming a practical indicator of service reliability. Questions around technician availability, training continuity and long-term staffing plans may increasingly influence procurement discussions. As maintenance demand continues to place pressure on available resources, providers with a stable and well-developed workforce may be better equipped to deliver consistent support over the life of an aircraft maintenance program. ...Read more
