Non-destructive testing is a technologically advanced technique to detect and evaluate defects in materials. Destructive testing is used to identify the characteristics of aircraft components, including tensile strength, fracture toughness, and flexibility. In the aerospace industry, NDT plays a primary role in designing, manufacturing, and maintenance of an aircraft. It is the most accurate methodology to test the aircraft component and materials without destruction.
With the advent of the fourth industrial revolution, NDT technologies are also integrating the advancements called NDT 4.0, aimed at greater connectivity. The connectivity is spread across all levels, from testing and measurement to data transfer and storage to decision-making and analysis to reporting and conclusive actions to resolve by decision-makers.

Innovation and Integration of Artificial Intelligence Algorithm to Enhance Accuracy Significantly
Non-destructive testing (NDT) methods use complex machinery and equipment for excellent results in flaw detection. The technological advancement in sensors, the advent of the Internet of Things (IoT), and wireless sensors fuel the demand for NDT due to exceptional accuracy in the testing results. The highest accuracy is provided by various ultrasonic testing tomography of rebar. The testing is well-equipped with the optical positioning system and A.I.-supported software algorithm. The analysis algorithm allows precise identification of probe positioning in the measurement procedure.
In 2018, Lynx Inspection Company launched Predictive 3D Radiography for flaw detection and analysis. The company combined 3D technology and X-ray imaging technology to analyze complex internal and external structures. The company is changing machine vision solutions for part manufacturing companies at affordable prices. For instance, in December 2021, according to VisiConsult, PFW Aerospace, the aviation supplier and a subsidiary of Hutchinson, has been evaluating the integration of AI to facilitate high non-destructive testing quality standards.

Increasing Adoption of NDT in Aerospace Industry Will Boost the Non-Destructive Testing (NDT) Market Growth
The aerospace industry requires the best quality structure, material, and strength standards. The technique is also called Non-Destructive Evaluation (NDE), and Non-Destructive Inspection (NDI), Non-Destructive Examination (NDE). Failure in surface, strength, and cracks could lead to numerous risks, including fatal accidents and loss of lives. According to the report by an aviation consulting firm, in 2018, the rate of fatal accidents for large commercial planes was 0.3 accidents per million flights and decreased to 0.18 accidents per million flights in 2019. NDT is a regularly used testing method in which aircraft parts and components are inspected before being assembled. Aircraft components are highly prone to fatigue cracks that can grow after a certain period.
According to Oliver Wyman, the global fleet maintenance, repair, and overhaul market was USD 81.9 million in 2019 and is expected to surpass USD 116 million by 2029. Almost 80% of inspection is performed through the visual inspecting testing method in aircraft across the globe to identify signs of damages. However, several testing methods and techniques, such as liquid penetration, acoustic emission testing, electromagnetic testing, ground penetration, radiographic, magnetic particle, and eddy-current testing, are gaining traction in the inspection of an aircraft component. The availability of excellent methods for finding cracks, flaws, and leaks in the system, components, and parts of an aircraft will boost the market growth in future.
High Demand for NDT Methodology in Oil & Gas and Power Industries to Boost Market Growth
The NDT technique involves research & development (R&D) methods, training, and service-based supply chains used in the oil & gas, automotive, and power industries. In the oil & gas industry, this technique is used to inspect the internal & external corrosion of the oil & gas pipeline. Several methods are used, including visual inspection, liquid penetrant inspection, magnetic particle inspection, and ultrasonic inspection. The NDT technique is used in the power industry to inspect pressure systems and steam & gas turbines. This technique is used in the nuclear power plant to inspect fuel rods, small valves, waste containers, and waste management infrastructure. Therefore, the rising demand for NDT methodology in the oil & gas and power industries is propelling the market growth.
Furthermore, improvised NDT technologies can facilitate the inspections of pipes, valves, welds, pressure, and storage vessels in all production cycle phases to improve operational efficiency and reliability. These improvised NDT technologies inspect accurately and quickly due to technological advancements in instrumentation, probes, and software. For instance, in October 2020, Novosound launched the new advanced NDT products series such as Kelpie, Belenus, and Nebula. These products are designed to make NDT inspections simpler and more efficient to reduce downtime in the sector of energy, oil & gas, aerospace, and renewables.
Lack of Skilled & Qualified Personnel for Inspection Services May Limit Market Growth
Non-destructive testing (NDT) is used in several industrial, private, and commercial applications. Due to the excellent evaluation output, the array of end-use industries worldwide is projected to fuel the demand in the near future. The testing and analysis method has certain limitations faced by several users across the globe. NDT can be done only with high-value advanced instrumentations. The analysis operation to find cracks, flaws, leakages, and troubleshooting requires advanced machinery and instrumentations for the highest accuracy. Thus, shortage of qualified and skilled workforce to operate the testing instruments is anticipated to restrain the market growth. Furthermore, stringent government regulations and lack of skilled workforce hamper the market growth.
The NDT equipment usage requires a high level of training and several certifications to handle instrumentations, which can incur high costs for service providers operating in the market. Furthermore, the ongoing COVID-19 pandemic has majorly impacted NDT training worldwide due to the inability of movement, owing to government-imposed lockdowns and cancellation or delay of NDT training programs for the generation of skilled workforce.
