What Is NADCAP?
NADCAP is short for National Aerospace and Defense Contractors Accreditation Program. NADCAP is a conformity and quality assessment developed to ensure quality in aerospace manufacturing.
Before NADCAP, suppliers had to undergo audits for every single aerospace customer they wanted to work with. This proved to be expensive and time-consuming, not to mention redundant. Many major aerospace manufacturers had similar criteria regarding process and quality and were performing near-identical audits.
The solution was NADCAP. Proposed in 1989 and passed in 1990, NADCAP created a single, standardized audit that most aerospace customers deem rigorous enough to meet their exacting standards. Now, undergoing a NADCAP audit opens the door for suppliers to work with many different aerospace customers.
Purpose of NADCAP Welding Standards
Aerospace products are expected to perform under rigorous conditions and in extreme environments, requiring a different approach to accreditation than consumer or even industrial products. The purpose of NADCAP welding standards is to establish that all aerospace welding processes and procedures conform to a defined set of expectations. This has several key benefits for aerospace suppliers, manufacturers, and other industry participants.
Consistency
While many regulatory and accreditation bodies conduct audits based on final product quality, NADCAP conducts audits of processes. Every step of the aerospace welding process, from the way the welder receives the work order to final product delivery, is closely inspected by an experienced auditor to ensure that expectations are met. Some of the processes reviewed during a NADCAP audit include:
- Material sourcing, purchasing, and allocation.
- Outsourcing.
- Documentation.
- Equipment maintenance and use.
- Operator practices.
Focusing on best practices throughout the process leads to superior quality at the final product stage.
Meets Safety Standards
By reviewing processes rather than the final product, NADCAP audits can uncover opportunities to improve worker safety. NADCAP welding standards are built around safety best practices, allowing auditors to support suppliers in improving their safety practices and protecting their workers.
Highlights Opportunities for Improvement
Preparing for an audit can be a little stressful, but every audit presents an opportunity to make improvements. NADCAP auditors will provide feedback and guidance regarding areas for improvement, giving suppliers the opportunity to establish better aerospace welding practices and reap the benefits.
Increase Market Visibility
Many aerospace companies and customers will only work with suppliers that have achieved NADCAP accreditation. Passing a NADCAP audit makes suppliers more visible to potential customers, creating more opportunities to do business.
NADCAP Certification Process
The NADCAP accreditation process differs slightly depending on the process for which you are seeking accreditation. Separate audits are required for each service area. However, most audit processes follow the same general format:
- The supplier requests the audit. Usually, they will receive a hefty packet of information about what to expect and how to prepare for the audit.
- The audit is scheduled, and an auditor is assigned.
- The auditor performs the audit and writes and submits their report.
- If the auditor notices and reports any issues, the supplier has a chance to make corrections and respond.
- The accreditation body reviews the report and the supplier’s responses. Once the accreditation body is satisfied that all issues have been corrected, the report goes to a task group for review.
- The supplier receives their NADCAP accreditation.
NADCAP accreditations must be renewed every 12 months.

What Is an Aerospace Actuator?
An actuator is a device or component that converts power into motion. Actuators come in a tremendous range of sizes and functions and can convert power into pressure, temperature, and mechanical movements. Each type of actuator works a little differently, depending on the medium used to generate force, such as compressed air, pressurized fluid, electricity, and rotary motion. The role of the actuator is to convert that power into motion or force.
An aerospace actuator is, quite simply, an actuator that performs these functions in an aerospace environment, usually onboard an aircraft. Aerospace actuators are among the most important components aboard an aircraft, triggering trigger functions as simple as opening or closing a valve or as complex as lowering the aircraft’s landing gear. Actuators play a critical role in the reliable function of engine turbines, autopilot systems, and other large assemblies and systems.
Types of Aircraft Actuators
There are several types of aerospace actuators already in heavy use, and new varieties are currently in development. Here are the most common types of actuators seen in the aerospace industry.
Linear Actuators
Linear actuators convert rotary motion into linear motion and are among the most common types of aircraft actuators. They can push, pull, and hold components of all sizes with more power, speed, and precision than the human body alone is capable of. As a result, linear actuators have many applications throughout an aircraft. Common examples include:
- Engaging and retracting aircraft landing gear.
- Engaging the aircraft’s wing flaps.
- Controlling reverse thrust functions.
Hydraulic Actuators
Hydraulic actuators use fluids to generate power, force, and torque. Hydraulic actuators are extremely powerful and can generate immense amounts of force while weighing relatively little and without taking up too much space, making them an excellent choice for high-force applications.
Hydraulic actuators offer several other key advantages. Hydraulic actuators don’t use any electricity and are easy to maintain compared to some other types of aircraft actuators. They can also be engaged very quickly, which is advantageous in many circumstances.
Applications for hydraulic actuators include:
- Aircraft landing gear.
- Wheel brakes.
- Constant-speed propellers.
Solenoid Actuators
Solenoid actuators convert electrical energy into mechanical action via the use of electromagnetics. Wire is coiled tightly around an iron core with a ferromagnetic plunger. Running an electrical current through the coil generates a magnetic field, which triggers the movement of the plunger.
Solenoid actuators operate quickly and can be easier to install than some other types of aircraft actuators. Solenoid actuators are utilized throughout the aircraft for a wide variety of applications, including:
- Starting aircraft engines.
- Deicing systems.
- Evacuation systems.
- Opening and closing of valves to control the flow of fluid and air in fuel metering units, engine control systems, and environmental control systems.

Understanding the Impact of The Aerospace Industry & the Environment
From major aircraft manufacturers to smaller supplies, virtually every branch of the aerospace industry is exploring sustainability and sustainable alternatives to common practices and materials. Many of the big names—Pratt & Whitney, Boeing, Airbus, Kaiser—have made public announcements about their sustainability initiatives and promises as they work to create more sustainable aircraft. And lots of smaller players are following suit.
Because the industry is so diverse and far-reaching, aerospace companies are pursuing many different strategies for sustainability and eco-consciousness. Some areas being explored include:
- Energy consumption. Aerospace manufacturers are reducing energy consumption in manufacturing and developing aircraft that consume less fuel or utilize more sustainable energy sources.
- Water consumption. Many sectors are exploring new manufacturing techniques that consume less fresh water.
- Waste reduction. Efficient manufacturing practices and strategic buying can result in less waste of materials and unused components. Additionally, aerospace manufacturers are experimenting with both recycled materials and closed-loop recycling systems.
- CO2 emissions. Many aerospace companies are leveraging the above strategies and others to decrease their carbon footprint or work toward carbon neutrality.
- Material selection. Many aircraft and component manufacturers are phasing out hazardous materials that may pose a threat to the environment. In the aerospace industry, more than 1,700 materials are subject to regulatory oversight. Initiatives such as the Restriction of Hazardous Substances Directive (RoHS) and the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACh) play a vital role in this shift.
Sustainability is also being lauded as a sign of innovation and smart business. Bjorn Hansen, Executive Director of The European Chemicals Agency (ECHA), has stated, “It’s clear that the most innovative companies are those that have adopted a green mindset.”
How NMG Reduces Waste & Pollution
At NMG Aerospace, sustainability and conservation are important to us. We’ve initiated a number of sustainable practices at our manufacturing facilities, and we’re always investigating ways to take our green approach to the next level. Here are a few things we do to play our part:
Reducing and Recycling Materials
Material waste can be a major challenge in the world of manufacturing. That’s why we strive to recycle as much as we possibly can. This includes plastic materials and machining debris, such as metal chips or rejected parts. We also buy smaller stock for machining aerospace components so we can reduce waste overall. Whenever possible, we rework parts rather than throwing them out.
Better Facility Practices
In addition to better material management and recycling, we’ve also adopted many basic practices to cut down on energy consumption and carbon output in our own buildings and facilities. For example, all of our lights are programmed to turn off automatically, so not a single bulb is left burning longer than necessary. Small steps like this add up over time, which is why we never hesitate to adopt even the most minor adjustment to make our business more sustainable.
More Efficient Packaging
Anyone who has ever ordered something online is familiar with the phenomenon of an oversized box with a single, comically small item inside. While this may be amusing, it’s an environmental error for several reasons. First, oversized packaging requires the consumption of substantially more material than is necessary. Second, shipping an oversized package drives up our collective shipping carbon footprint.
NMG is committed to right-sized packaging for every shipment, so we can use our shipping materials more efficiently and reduce our shipping carbon footprint.
Our Commitment to Sustainable Manufacturing Practices
With over 40 years of experience, NMG has played a long-standing role in the aerospace industry’s ongoing journey toward greater sustainability. From our on-site initiatives to our manufacturing practices, we’re proud to support our customers as they strive to build a more sustainable aircraft.

How Manufacturing Partnerships Are Beneficial
Aerospace manufacturing partnerships offer a wide range of significant benefits and advantages to aircraft manufacturers, tier suppliers, and specialized service providers.
Major aircraft manufacturers who outsource multiple steps to a single partner reap the benefits of greater efficiency. There is no need to coordinate transportation to multiple facilities, no excess risk of supply chain disruptions or delays, and none of the stress associated with coordinating communication and logistics with multiple parties. Some manufacturing partnerships can even incorporate automated ordering mechanisms, cutting down on the administrative hours required to manage the partnership and further increasing efficiency for the aircraft manufacturer.
A truly exceptional manufacturing partner can also offer insight to improve product design and make the manufacturing process easier and less expensive. Experienced aerospace manufacturers can leverage their many years of manufacturing experience to identify opportunities for improvement, greater efficiency, and cost savings.
Collaborations in manufacturing can serve as a failsafe or backup as well. If an aircraft manufacturer experiences a delay or other issue in house, they can quickly outsource production to their aerospace manufacturing partner, minimizing any disruption or slowdown. An aerospace manufacturing partner may also be able to find a timely solution if another supplier failed to complete a project on time or without defects.
How NMG Collaborates With Others
NMG Aerospace is proud to have a rich history of supporting our customers in times of need and developing collaborative partnerships that resulted in streamlined production, cost savings, and reduced administrative headache. Here are several noteworthy examples.
- NMG spent several years performing subcomponent machining for a major Tier 1 aircraft systems manufacturer for the Lockheed Martin F-35 Lightning II. The manufacturer eventually entrusted NMG with not only machining, but also assembly and testing. NMG has also advised the manufacturer on nearly 200 separate occasions on design refinements that have resulted in better manufacturability, so certain parts became easier and less expensive to produce. NMG has become a vital and trusted partner to this particular manufacturer.
- A major Tier 1 aircraft systems manufacturer engaged both NMG and a second supplier to make a particular part for a high performance aircraft platform. NMG had the foresight to create a contingency plan in the event that the second supplier was unable to fulfill the contract for the customer. The second supplier did, in fact, suffer a setback, and since NMG already had the raw materials on hand to serve as a backup, we were able to jump into motion immediately and ensure that our customer got what they needed in a timely manner.
- A major business aircraft manufacturer approached NMG to retrofit an entire fleet to address a failing part designed and manufactured by a previous supplier. NMG has refined the design and the manufacturability of the part, well within the lead time requested by the manufacturer.
- A major aerospace machining supplier won an orifice support tube manufacturing contract a few years ago, only to discover that the parts are very difficult to reliably produce. The supplier turned to NMG for support and wound up outsourcing the entire project to NMG, who now produces the part for the supplier’s customer on the supplier’s behalf.

How Aerospace Manufacturers are Managing Aerospace Industry Growth
The aerospace industry has experienced some significant ups and downs in recent years. In the decade leading up to 2020, the aerospace industry experienced continuous growth, peaking around 2018. However, the advent of the COVID-19 pandemic led to the worst downturn in the history of manned flight. Virtually every part of the industry, from airlines to aircraft manufacturers, suffered.
Now, in 2023, the industry is back on a strong upward trajectory, as people return to air travel in droves. Numerous factors are contributing to aerospace industry growth, and the aerospace manufacturing sector may be poised to make it possible.
Why is the Aerospace Industry Growing?
End of Covid Pandemic
Throughout the COVID-19 pandemic, travel restrictions and border closures led to a dramatic reduction in both international and domestic flights. Some experts say that international flight volume decreased by as much as 68%, while domestic flights dropped by 40%. Aerospace and aircraft manufacturers experienced major downturns as a result.
While some countries are still refusing or restricting entry to unvaccinated individuals, virtually all other travel restrictions have long since been lifted. Business travel remains a bit muted, but leisure travel has made a booming return.
Advancing Military Technology
According to Deloitte, the defense segment of the aerospace industry is stable and on track to outperform commercial in the coming years. Technological advancement is an evergreen priority of many branches of the military, but the Russian invasion of Ukraine has prompted a worldwide bolstering of defense budgets and heightened demand for equipment. The United States and many European countries have reportedly budgeted a total of $204 billion to modernize their militaries, which could very well lead to a wealth of advancements and breakthroughs and meaningful industry growth.
Renewed Interest in Space Travel
Another major contributor to aerospace industry growth is growing interest in space travel. NASA and SpaceX have been the primary players for a while, but plenty of private companies and startups are beginning to venture into space travel. We set a new record for orbital launches in 2022, and countless small satellites are launched on a regular basis.
This is partially driven by growing interest in both establishing new industries in space and expanding existing industries toward the stars. Examples include space-based manufacturing and solar power, asteroid mining, and space tourism.
Another contributing factor is the growing interest in reusable launch vehicles. Both NASA and SpaceX have experimented and achieved success with reusable assets, and more advancements are likely on the horizon.
What Aerospace Industry Growth Means for Aerospace Component Manufacturers
Aerospace component manufacturers have the potential to reap tremendous benefits if they leverage this season of aerospace industry growth effectively. This requires a few key strategies:
- Offer supply chain visibility and resilience. After the supply chain disruptions that accompanied the COVID-19 pandemic, the aerospace industry is eager for stability and predictability throughout the aerospace manufacturing supply chain. According to the United States Department of Defense, aerospace component manufacturers should strive to be as reliable and transparent as possible, to soothe the anxieties of customers and ensure an increase in on-time deliveries.
- Offer flexibility and agility without sacrificing quality. Aerospace technology is advancing very quickly, and aircraft manufacturers are working hard to keep up. Aerospace component manufacturers can serve their customers by building in-house processes that allow them to turn on a dime and make fast changes while still delivering top-quality components.
- Be diligent about hiring and retention. Many manufacturing sectors are struggling with the ramifications of an older workforce and the challenge of hiring and keeping good talent. Aerospace component manufacturers should invest meaningfully in growing and nurturing excellent teams in every part of their business, so they are at the ready to meet their customers’ increasingly frequent staffing and shortages driven needs.

Types of Aircraft Industry Goals
Different aircraft types have different purposes and performance requirements, which requires different approaches to the product design process. Understanding the goals and service environments of a specific aircraft type from the very beginning allows designers, engineers, and manufacturers to make confident decisions at every step of the process that support the ultimate purpose and requirements of the project.
Commercial
Reliability plays a key role in the design and manufacture of commercial aircraft. A single commercial aircraft may perform 3,000 landings in a single year, every single one of which must be reliably safe.
Commercial aircraft must also be designed to maximize passenger comfort. The aircraft must be very stable, flying straight level, with very few erratic maneuvers that may frighten passengers or trigger motion sickness. Additionally, commercial aircraft designers often choose to place the fuselage over the wings to make the cabin quieter.
Commercial aircraft may also be designed for fuel efficiency. Even marginal fuel savings on a single flight can translate to massive cost savings across a single day, year, or airline. Major airlines may be highly motivated to purchase aircraft designed for fuel efficiency due to the savings they may realize as a result.
Military
The average military aircraft performs fewer landings per year—perhaps 800 or so—than a commercial aircraft. However, those landings are likely to occur in far more intense conditions and without advanced planning. These aircraft must be designed to protect both the crew and the aircraft in the likely event of a rough landing in rugged, unpredictable conditions.
Stability is less of a priority for military aircraft. Unlike commercial aircraft, military planes do have to perform more intense maneuvers while in flight. In fact, the ability to perform complex maneuvers at high speeds may be a top priority, depending on the aircraft and its purpose. This may include the ability to provide extremely close support for ground troops. This must be considered when designing the aircraft and its controls.
There may also be special functions to consider when designing military aircraft. Some military planes are amphibious and can take off and land on solid ground or water. Others have vertical take-off and landing (VTOL) capabilities for entering and exiting dense terrain with no runway. These special features may affect virtually every part of the aircraft design, which is why understanding these goals from the very beginning is so important.
Meeting Aircraft Design Needs
Aircraft companies have specific criteria in mind when looking for design and manufacturing support. However, these criteria can differ depending on the type of aircraft being manufactured.
Commercial
Production backlogs and delays are an ongoing problem and often a significant source of frustration in the world of commercial aircraft. These companies are often looking for someone who can keep them on track without slowdowns or bottlenecks.
Another top priority for commercial aircraft manufacturers is rapid innovation. These companies are highly motivated to incorporate new technology quickly so they can gain an edge on their competition. They need a manufacturing partner who can support fast-paced innovation, so they can get those new ideas to market as quickly as possible.
Military
Developing a military aircraft often takes longer. Many new technologies and developments may be tested in the process, some of which may be so cutting-edge that they’re being tested and validated for the first time. Plus, because a military aircraft may fly so many varied missions during its service life, its components must be able to withstand a wider range of service conditions. Military aircraft manufacturers seek design and manufacturing partners who can develop components rugged enough for their planes.

Importance of Aerospace Quality Testing
Quality testing is often the final step of the product development process before launch. The data gathered during the quality testing process can help determine whether the product can withstand its service environment and perform as designed, even in harsh conditions. This is critical for designing and manufacturing a reliable aerospace product.
Additionally, quality testing is often vital for doing business in the aerospace industry. Many aircraft manufacturers will only purchase components that comply with certain aerospace quality standards, such as industry standards or their own custom specifications. Investing in comprehensive quality testing demonstrates commitment to producing quality products and can bolster a manufacturer’s reputation in the industry.
Quality Testing Processes for Aerospace Parts
Because every aerospace component has a unique and specialized role, the quality testing process will look different depending on the product being tested.
The first step to the quality testing process is to determine whether there are any specific compliance tests that need to be considered. For example, BMS 13-48 is a Boeing spec that should be considered when assessing the quality of wire and cable, and Boeing Safety Standard (BSS) 7239 might be important when testing coating, textiles, and composites. These tests are often mandated by specific manufacturers or larger governing bodies as a way to establish consistent quality standards throughout the industry and are especially vital when conducting quality testing before a product launch.
The next step is to understand what the client is seeking to achieve. Are they in the research and development (R&D) stage for a new product or seeking to learn something highly specific about a certain component? Understanding the client’s goals is vital to designing an effective aerospace quality testing plan.
The quality testing team should also endeavor to understand the product’s service environment. Aerospace components often operate in fairly extreme conditions, and quality testing can be incredibly valuable in determining whether a given component can operate as designed while withstanding an intense environment.
Once the necessary tests have been chosen, the testing team can determine the most sensible order of tests and complete any preparations that must take place before testing can start.
At this point, the testing team can execute the quality testing plan. As previously stated, the actual testing process may be very different from one component to another. A component located on the exterior of the aircraft will be subjected to very different laboratory conditions than a component that’s part of an interior system.
Data is collected throughout the quality testing process. Once testing is complete, that data can be gathered for review and analysis. Interpreting the results determines whether the component fulfilled the testing requirements and any next steps that must occur.
In some cases, completion of testing is the final task before going to market. But, depending on the goals of testing and the development stage of the product, testing data may serve as a guidepost for next steps. For example, the product may need to be refined, and the testing data can offer insight into the refinement strategy. Or data can help a manufacturer decide between multiple materials or products, so they can move forward with the stronger contender. Either way, determining what to do after testing is complete is an important part of the quality testing process.

Strategies include focusing on math and science coursework, seeking internship and co-op experiences, and considering a master’s degree in the future.
Math & Science Centered Schooling
Education is the first step toward a successful career in aerospace engineering. Aspiring aerospace engineers can take the first steps by focusing on chemistry, physics, and mathematics coursework as early as high school. Math is especially important in any type of engineering, and working hard in high school can pave the way for you to take even more advanced math classes once you reach college.
Once you enter higher education, you should pursue degrees in engineering or a related field. Additional coursework in chemistry, physics, and math at the collegiate level is also highly beneficial since those skills will support their core curriculum and likely come in handy in the future. You might also consider taking a few courses in computer science and software engineering, since the skills taught in these courses may also benefit their career aspirations.
Internships & Co-op Experiences
Co-ops have been part of the engineering experience for over one hundred years. Co-ops are an excellent opportunity to learn on-the-job skills, such as communication, client management, relationship building, problem-solving, and other skills that can’t be learned in a classroom. Spending time in an active work environment gives you a chance to learn how people use the products, how to market different products, and how to apply engineering fundamentals to real-world problems. And while not all co-op experiences lead to job offers, it’s not uncommon for co-op students to become employees at the same company after graduation.
Consider a Master’s Degree
Not every aerospace engineering job requires a master’s degree. Many engineers go their entire careers with just a bachelor’s degree and enjoy great success. However, there are some roles that do require an advanced degree, specifically a Master of Science in Aerospace Engineering (MSAE). If you have aspirations of leadership and advanced technical roles, a master’s degree can be extremely beneficial.
Some colleges and universities offer five- or six-year programs that combine a bachelor’s and master’s degree into one streamlined program. This allows young professionals to enter the workforce having already earned an advanced degree, which can open up more job opportunities for them as they begin their careers. That being said, plenty of aerospace engineers choose to go back to school later in life to earn their master’s degree.
Job Growth for Aerospace Engineers
As previously stated, the job market for aerospace engineers is expected to grow by 6% every year, with new opportunities appearing all the time. And there is no single path forward for someone interested in a career in aerospace engineering. An aerospace engineering professional can explore countless possibilities, including:
- Designing aircraft and spacecraft.
- Designing the parts, components, and systems within an aircraft as a mechanical engineer.
- Building blueprints and technical schematics as a drafter.
- Leading teams of engineers and support staff.
- Working directly with customers in a sales or business development role.
- Teaching aerospace engineering to college, university, and grad school students as a professor.
There are so many different jobs for aerospace engineers, all of which allow you to pair your passion for aerospace engineering with other talents and interests.
It’s also worth noting that there are multiple fields within the aerospace engineering industry that person may be interested in. In addition to commercial aircraft, there are robust sectors for military aircraft, private aircraft, and space exploration, along with academia.

How Landing Gear Works
Landing gear is the only part of the aircraft that makes contact with the ground and supports the weight of the craft when the plane is not in flight. Whether the plane is at rest, taxiing, turning, or accelerating for takeoff, the landing gear is responsible for transmitting those forces between the aircraft and the ground.
Well-designed landing gear is critical to safe takeoff and landing. Landing gear must be designed for exact balance, so the plane can tilt slightly for takeoff without the tail striking against the surface of the runway.
The tires and wheels must withstand the same pressures as a standard automotive tire: bumps, loads, cornering, and other forces.
Landing Gear Design Process
Some aircraft manufacturers make the mistake of waiting until late in the process to begin designing the landing gear. Because the design and integration of the landing gear affects the entire aircraft, waiting too long to think about landing gear is a mistake—and can necessitate a large-scale redesign. The structure of the landing gear must be able to bear the load of the plane, and the plane itself must be built to include space for the landing gear to be stored while in flight.
Client Goals
It’s important to start with a conversation about the overall design of the plane, as well as considerations such as performance and safety requirements, timeframe, technology, resources, and budget. These factors may affect material and design choices.
Choosing Configuration
Aircraft manufacturers may have multiple landing gear configurations to choose from. Some options are lighter than others, some offer better on-the-ground visibility to the pilot, and others are better suited to different types of landing surfaces, such as groomed runways versus field environments. The right choice depends on the purpose of the plane and where it will be used. In any case, it is vital to choose a configuration that offers stability and equilibrium.
Meeting Specifications
Each type of aircraft may be required to meet different specifications and regulatory requirements. It is crucial to understand which specifications must be considered when designing landing gear.
Analysis, Testing, & Qualification
Today’s testing technology allows manufacturers and designers to use models and real-world tests to recreate stress, fatigue, and other forces in a controlled environment. This allows for careful analysis of each component of the landing gear to ensure that it can withstand its environment and perform as expected. Designers should be mindful to include time for analysis, testing, and qualification in the design timeline.
Design Factors to Consider
There are several important variables to consider when designing landing gear for aircraft of any size and variety. Landing gear is subjected to a variety of forces while in service, and understanding these forces is key to designing an effective landing gear assembly.
Load Weight During Landing
Of course, aircraft landing gear must support the weight of the plane while taxiing and while at rest. However, the landing gear must also be able to withstand much greater loads and pressures while the aircraft is actually landing. Bumps and other hazards on the landing surface also add additional load to the landing gear.
Side Loads
It is vital to design a landing gear structure strong enough to withstand side loads. A side load is any pressure placed on the aircraft’s wheels and landing gear from the side due to cornering, turning, or crosswinds. This largely depends on where the plane will be used. Side loads put a lot of pressure on the joint where the landing gear attaches to the aircraft and may even cause bending.
Landing Distance
Landing distance is an important factor to consider when designing landing gear. For example, an aircraft that will land on aircraft carriers needs landing gear that can withstand a firm, swift, short-field landing, rather than the slow, gentle descent of a commercial aircraft landing on a long, paved runway.

Takeoff and landing put significant thermal and mechanical stress on the plane’s landing gear, which means aircraft wheels and brakes must perform their essential functions under highly rigorous conditions. This is especially true of sport aircraft, which operate under competitive conditions and often don’t take off from or land on groomed, paved runways.
Every component of the landing gear, including the wheel, must be tested and inspected to ensure that the assembly can perform as expected, every time. Aircraft wheels are prone to failure if they develop cracks, dents, or other defects, so it’s vital to examine the wheel carefully for any sign of damage or inconsistency.
Testing Aircraft Wheels
Many aircraft wheels must comply with regulatory requirements or undergo testing in a formal setting. Wheels are also subjected to periodic inspections before a flight to ensure structural integrity.
Passing a Wheel Stress Test
There are two categories of stress testing for aircraft wheels: nondestructive testing and eddy current inspection.
Nondestructive testing entails examining the wheel for issues without destroying it. The plane wheel is not subjected to any crush, rust, or impact tests. Instead, the wheel is inspected for any signs of damage, such as cracks, nicks, grooves, impact, corrosion, and other wear and tear. The wheel bearing will also be inspected for loose bolts, markets, heat damage, or other issues.
Eddy current inspection uses a forced air current to test the seat of the wheel bead. The goal is to detect any issues, flaws, or weaknesses that may impact the plane wheel’s performance and which the human eye may not be able to detect. The bead experiences high stress during takeoff and landing, so it’s crucial to ensure that the area is not damaged or cracked before takeoff.
STOL Competition & Matco Wheels
Many sport aircraft pilots build their own planes to compete in short takeoff and landing (STOL) competitions. The goal in a STOL competition is to cover as little distance as possible during takeoff and landing, often under 15 feet. Needless to say, these rigorous acceleration and braking events put significant stress on the aircraft’s wheels, which necessitates an aircraft wheel that can withstand the heat, pressure, and fatigue.
Matco Aircraft Landing Systems is proud to manufacture reliable, durable wheels and brakes that perform exceptionally well in STOL competitions and similar conditions.
