Aerospace assembly services rely on aviation assembly technology to construct and piece together aerospace components into a functional aircraft system. This process may also be called fabrication assembly.
Because so many aircraft systems fall under the definition of mission-critical, precision is of the utmost importance for aerospace assembly services. Each component must fit and interact exactly as intended to ensure reliable functionality, even in intense circumstances. For this reason, it is critical to engage an experienced aerospace fabrication assembly and design partner who has the experience, industry expertise, and aviation assembly technology to ensure the necessary precision.
One example is aircraft landing gear. An aircraft’s landing gear is its only component that makes direct contact with the runway during takeoff and landing and is responsible for bringing the plane to a halt in a timely manner, even if the runway is wet or conditions are otherwise less than ideal. Shoddy assembly of the landing gear could compromise its reliable performance and lead to a wide range of consequences, from an unbalanced landing to a catastrophic collision or belly flop. Precision during the assembly process goes a long way to ensuring that the landing gear and other critical systems perform exactly as designed.

Excellent aircraft operations rely on durable materials that can withstand high heat and rigorous conditions. As the aerospace industry becomes more and more advanced, the demand for high-temperature materials continues to grow.
High-temperature alloys and materials are critical to the aerospace industry for several reasons:
Extreme Operating Environments
An airplane that takes off from a well-groomed runway for a scheduled domestic flight is not insulated against extreme operating conditions. Domestic fleets and rugged military aircraft alike may be subjected to high heat, severe cold, mechanical stresses and pressures, corrosion, radiation, and thermal shock while in operation.
With this in mind, there are two benefits to choosing high-temperature alloys for aerospace components. First, the materials can withstand high heat throughout the flight. Second, the materials can maintain their vital performance attributes even when subjected to high heat, which ensures reliable endurance against the rigors listed above.
Performance and Safety
High-temperature materials and aerospace alloys allow aerospace manufacturers to improve fuel efficiency and other parameters. For example, turbine efficiency can be increased by 5-6% by boosting the service temperature of the aircraft by 200°C. By leveraging high-temperature materials, aircraft can be operated at higher temperatures, and with the appropriate thermal barrier coatings and cooling systems, the aircraft can achieve better fuel efficiency.
High-temperature materials often have greater flexibility, radar absorption, and flutter suppression than their counterparts, along with high strength-to-weight ratios. This leads to greater stability throughout the aircraft.
Enabling Advanced Designs
The performance attributes of high-temperature materials and their compatibility with advanced manufacturing methods will likely translate to tremendous advancements in aerospace manufacturing and performance in the coming years. High-temperature materials may allow aerospace engineers to solve long-standing challenges and unlock new innovations in aerospace technology by raising the ceiling on operating temperatures.
High-Temperature Alloys and Other Materials for Aerospace
High-temperature materials range from alloys and polymers to composites featuring fibers and matrices. Examples of aerospace alloys and other high-temperature materials include:
Nickel Alloys
Nickel alloys are commonly used in aerospace applications, thanks to their excellent resistance to corrosion and temperature fatigue, caused by repeated exposure to heating and cooling cycles during flight. Nickel alloys are strong and easy to fabricate.
Titanium Alloys
Like nickel alloys, titanium alloys are highly resistant to corrosion and temperature fatigue. Additionally, titanium alloys are quite lightweight, a desirable attribute for manufacturers for whom lightweighting is a priority.
Copper Alloys
Copper alloys boast a few key performance attributes, including resistance to oxidation and creep, long low-cycle fatigue, and excellent strength at high temperatures. Some copper aerospace alloys are especially well suited to complex shaping, due to low thermal expansion.
Ceramic Matrix Composites (CMCs)
CMCs combine ceramic fibers with a ceramic matrix, resulting in a class of material that demonstrates excellent thermal stability, strength, and toughness. CMCs are a popular choice when lightweighting is a concern, since they are much lighter than metal alloys. CMCs are often used for jet engine components and heat shields.
Carbon-Carbon Composites
Carbon-carbon composites, made of carbon fibers embedded in a carbon matrix, are exceptionally well suited to endure the tremendous thermal load of reentry. These materials offer superb thermal conductivity and mechanical properties and are often used for heat shields.
Carbon-carbon composites offer inferior thermal shock and oxidation resistance to other high-temperature materials.
High-Temperature Polymers
Thanks to tremendous leaps in polymer composite research and high-temperature polymerization, high-temperature polymers with incredible performance attributes are becoming increasingly popular for aerospace applications. High-temperature polymers retain their thermal stability at high temperatures and are highly resistant to a wide range of chemicals. These materials demonstrate incredible tensile strength while weighing less than metal aerospace alloys. Additionally, the excellent thermal insulation properties of high-temperature polymers make them a popular choice for parts designed to protect sensitive aircraft systems and components from heat and electromagnetic interference.
Future Directions for High-Temperature Materials
The future of high-temperature materials is incredibly promising, with valuable research occurring in several key areas:
The next generation of aerospace alloys may outperform existing superalloys at ultrahigh temperatures. This has the potential to allow for tremendous innovation in turbine blade design.
Combining high-temperature materials with advanced manufacturing methods, such as additive manufacturing and powder metallurgy, may allow aerospace manufacturers to achieve more complex geometries.

There are many ways to practice sustainability in aerospace. One popular and powerful strategy for improving sustainability is lightweighting, a central focus for aerospace research and development.
What Is Lightweighting?
Lightweighting refers to any design or manufacturing process that aims to reduce the weight of a part or component without compromising performance, durability, or reliability. Lightweighting may include optimizing the design of a component or part to eliminate needless bulk, opting for a lighter material, or a combination of changes.
The Science Behind Weight and Fuel Efficiency
The purpose of lightweighting is to reduce the overall weight of an aircraft or other vehicle, thereby decreasing the power needed for flight and improving fuel efficiency—a key sustainability metric.
According to an article from Quality Magazine, “eliminating one kilogram of material from an airplane reduces greenhouse gas emissions by saving 106 kilograms of jet fuel every year.” This can have dramatic impacts at scale for aerospace companies.
For example, consider a midsized airline with a fleet of 800 vehicles. Imagine the airline decides to replace a few components in each aircraft with a lightweight material alternative, resulting in an average weight reduction of 2.5 kilograms, or roughly 5.5 pounds, per aircraft. One year later, the airline will have reduced its annual fuel consumption by roughly 212,000 kilograms or 44,700 gallons. Assuming an average cost of $4 per gallon of jet fuel, the airline will save over $178,000 in a single year.
It’s worth noting that these calculations are based on incredibly modest numbers. At the 2022 International Materials Applications and Technology (IMAT) Conference, two researchers reported that strategic lightweighting initiatives can reduce the weight of the engine by up to 14% and the landing gear by up to 16%. Given that commercial aircraft engines weigh anywhere from 4,000 to upwards of 19,000 pounds, a 14% reduction in weight can have a tremendous impact on the fuel efficiency of the aircraft.
Why Lightweighting Matters in Modern Aircraft Design
The aerospace industry is one of many working to accommodate growing demands for sustainability and eco-friendly practices, such as lightweighting. This is occurring for several reasons:
For many consumers, sustainability is factored heavily into their purchasing decisions—and plane tickets are no exception. Sustainable practices, such as lightweight aircraft, are key to remaining competitive among passengers.
Materials That Are Changing the Aerospace Industry
The aerospace industry is experimenting with a wide range of materials to develop lightweight aircraft. This includes using established materials for new applications and exploring the use of new materials with exceptional properties. A few examples include:
Graphene
Carbon nanotubes
High-performance polymers
Advanced steel alloys, such as dual-phase steel
These materials offer the same reliability, durability, and performance as more traditional materials, at a much lower overall weight, supporting the goal of a lightweight aircraft. Strategically replacing heavier materials with any of these lightweight material alternatives reduces the weight of a given component and assembly without compromising the performance of the system.
The adoption of certain lightweight materials in aerospace manufacturing was made possible by incredible manufacturing innovations in recent years. These new manufacturing methods have allowed aircraft manufacturers to experiment with new materials and achieve greater efficiency overall. Manufacturing innovations enabling lightweight aircraft include:
3D Printing (also known as Additive Manufacturing): 3D printers create parts and components layer by layer. 3D printing and additive manufacturing are compatible with an incredibly wide range of materials, granting tremendous flexibility to the method. The potential applications for this new technology are virtually unlimited.
CNC Precision Machining: Unlike 3D printing, CNC precision machining creates parts by removing material from a solid piece of material. CNC machining allows for tremendous levels of detail and is a fantastic method for parts with tight tolerances.
Hydroforming: Hydroforming uses heated liquid media to shape metal pieces, often tubing, into precise shapes. Hydroforming generates less waste than other methods and is an excellent choice for irregular contours and complex parts.
Artificial intelligence (AI) and digital twins are also gaining traction in aerospace manufacturing. A digital twin is a digital replica of a real-world object, such as a part or aircraft. Manufacturers and engineers can simulate different environments and scenarios in a digital environment and observe the response and behavior of the digital twin, allowing them to predict the real-world performance of the part or assembly. This type of simulation testing is fast, efficient, and requires no prototypes, which can save time and resources, especially in the early stages of lightweight aircraft design.
Challenges in Lightweight Aerospace Component Production
While lightweighting offers tremendous benefits for aerospace companies, there are several challenges to consider when developing lightweight aircraft:
Compliance: Any given material for aerospace manufacturing needs to meet a lot of criteria before production begins. Lightweight aircraft materials must meet the requirements of the appropriate regulatory body and satisfy criteria for performance, durability, and safety.
Cost: While many lightweight materials are available at a comparable price point to their traditional counterparts, some are more expensive. Manufacturers must consider material costs against the benefits associated with a given material.
Manufacturing: Different materials behave differently in the manufacturing environment. Manufacturers must determine the appropriate manufacturing method, as well as compound formulation, when experimenting with lightweight materials.
Procurement: Depending on the state of the supply chain, certain lightweight materials may be more difficult to obtain. Ensuring a consistent supply can be a challenge, especially when working with a new material.
Manufacturers must be strategic and planful to overcome these challenges.

Why Sustainability Matters in Aerospace Manufacturing
The aerospace industry is one of many exploring ways to reduce its carbon footprint and adopt more sustainable practices. More and more consumers are naming sustainability among their core values and opting to patronize businesses that prioritize sustainable practices and invest resources into sustainability innovations. In other words, embracing sustainability may be critical to remaining competitive in the aerospace industry.
Many of these practices, such as sustainable materials, lightweighting, and waste reduction, happen at the manufacturing level. Aerospace manufacturing companies can contribute tremendously to the industry’s sustainability efforts by finding ways to leverage and implement sustainable practices.
Sustainable Materials Used in Aerospace Manufacturing
There are many ways to think about sustainability, from fuel consumption to recycling to waste management. One area rife with possibility for the aerospace industry is material selection. Strategic material selection can contribute to a wide range of sustainability goals, such as waste reduction, the use of more natural raw materials, and reduced fuel consumption by way of lightweighting.
Lightweight Materials
Many aircraft manufacturers are choosing lightweight materials as they pursue their sustainability goals. Choosing lightweight materials, or “lightweighting,” brings down the overall weight of the aircraft, which in turn reduces the amount of fuel required to fly the plane. Lightweighting can improve the fuel economy of the aircraft, with the compounding effect of dramatically reducing the fuel consumption of a single aircraft or an entire airline over time.
Bio-Based Composites
The aerospace industry has long relied on carbon fiber for aircraft manufacturing. Carbon fiber is strong, stiff, and durable, making it an excellent material for building airplanes. However, carbon fiber is usually made from fossil fuels, which may not align with some manufacturers’ sustainability goals.
Materials science experts have developed a new class of materials, called carbon composites, that may serve as an excellent alternative to carbon fiber. Carbon composites are strong and lightweight materials that offer many of the same performance attributes without using any fossil fuels. This new class of materials can be made from a wide range of biofibers and bioresins, like sugar cane and crop waste, water algae, bamboo, and others.
Thermoplastic Polymers
Thermoplastic polymers may be an attractive alternative to thermoset polymers and in fact already being used to create tooling and structural parts for fuselages and other components. Unlike thermoset polymers, thermoplastic polymers are 100% recyclable: This material can be melted and reformed over and over. While a broken or damaged thermoset polymer part must be discarded, a thermoplastic polymer part can be repaired by melting and reforming the damaged area—or recycled in its entirety to make a new part.
Additionally, thermoplastic polymers are lightweight materials compared to alternative options. Choosing thermoplastic polymer materials can be an excellent lightweighting strategy, which contributes to improved overall fuel economy. And because thermoplastic polymer parts can be connected by melting and welding the material together, there is no need for fasteners or other heavy components, which also supports lightweighting goals.
Even the manufacturing process for thermoplastic polymers is more sustainable. There is no need for an autoclave or cold storage, both of which consume considerable energy.
Recycled Materials
Many aircraft manufacturers are focusing their sustainability efforts on recyclable materials that can be returned to their raw state and remade. This includes aluminum, steel, titanium, and even carbon fiber. Choosing these recyclable materials cuts down on overall material consumption and waste production, two important metrics for sustainability.
NMG’s Commitment to Sustainable Manufacturing
NMG Aerospace is committed to exploring and adopting a wide range of sustainable manufacturing practices.
We make a conscious effort to cut down on material waste at our manufacturing facilities. We collect all machining debris, metal chips, and rejected parts, so we can reuse those materials, rather than letting them go to waste. We also place smaller stock orders to minimize leftover materials.

Ice accumulation poses a serious threat to aircraft safety and function. Ice can clog engine inlets and the vents on fuel tanks, compromising the mechanical performance of the aircraft. Ice formation on wings, tails, and propellers can alter the aerodynamics of the aircraft and reduce the pilot’s control over the flight. Ice buildup on the windshield can reduce visibility.
Simply put, unchecked ice accumulation introduces serious risk to any flight. Thankfully, most aircraft are outfitted with deicing systems to keep ice at bay.
What Is a Deicing System?
An aircraft deicing system is an assembly of components designed with the purpose of removing ice from an aircraft to alleviate any accumulation that might have a detrimental impact on flight and function.
There are a wide range of airplane deicing systems on the market, in three broad categories:
Inflatable Boots
Pneumatic boot systems are a classic example of an aircraft deicing system. The technology was first developed in the 1930s and has been standard technology since World War II. The boot is a long, inflatable rubber strip that is affixed along the aircraft’s wings, propeller, and tail, where ice most commonly accumulates. When the pilot inflates the boot, the outward force breaks any ice that has accumulated along the wing. The broken shards of ice are then simply blown away. This can be done repeatedly.
Timing is key with boot deicing systems. A boot can easily break through a thin layer of ice, but if the pilot waits until the buildup is too thick, a boot may not be sufficient.
Chemical Deicing Systems
A chemical deicing system uses glycol-based antifreeze solutions to address ice buildup. Electrical pumps force deicing fluid through tiny holes on the wings and other areas of the aircraft, and the fluid triggers a chemical breakdown of the accumulated ice. Chemical deicing systems can also be deployed preemptively to prevent ice buildup.
There are many different types of deicing fluid, differing in thickness and duration of efficacy. Fluids are chosen based on the speed of the aircraft and the severity of the anticipated ice buildup.
Thermal Deicing Systems
A thermal deicing system breaks down ice accumulation with heat. Some thermal deicing systems, called bleed air systems, route hot air from the engine through the wings and other surfaces to melt ice. Other systems, called electro-thermal systems, rely on embedded heating elements to heat wings and propellers.
Anti-icing vs. Deicing
There is an important distinction to be made between anti-icing and deicing systems. While deicing systems work to remove ice buildup, airplane anti-icing systems are engaged proactively to prevent ice accumulation from occurring at all. Aircraft anti-icing systems are often engaged continuously, whereas deicing systems are only used as needed.
Anti-icing is especially vital for windshields, wings, and engines. Ice buildup in these areas can compromise the safety and performance of the aircraft, which increases risk. Taking early steps to prevent ice accumulation is key to a safe flight.
There is significant overlap between aircraft anti-icing and deicing systems and technology. Some thermal systems keep the surface temperature of the wings above freezing at all times. Chemical systems can create a protective film or slick surface that prevents ice buildup.
Types & Applications of Deicing Valves Used in Aerospace
An airplane anti-icing or deicing system includes a number of different valves, each with a specific purpose related to directing and managing the flow of media. Examples include pressure regulation valves, distribution valves, relief valves, isolation valves, and solenoid valves.
Pressure Regulation Valves
A pressure regulation valve maintains constant pressure within the deicing system. The valve opens and closes to compensate for fluctuations that may occur in flight.
Distribution Valves
Distribution valves direct and control the flow of media through the deicing system. A distribution valve may divide a single stream of media into multiple streams to different zones or change the direction of flow.
Relief Valves
A relief valve is a safeguard against the dangers of excess pressure. When excess pressure builds up within a deicing system, the assembly can malfunction, leak, or even rupture. The relief valve is designed to quickly and safely release excess pressure, mitigating the risks of damage or malfunction.
Isolation Valves
For aerospace manufacturing applications, an isolation valve is used to stop the flow of media to certain zones of the deicing system.
Solenoid Valves
There are many applications for solenoid valves. In the context of a deicing system, solenoid valves control the flow of deicing fluid, air, and other media by opening and closing in response to electrical signals.

3D printing and additive manufacturing are making waves all over the world as industry after industry begins to adopt and experiment with these new technologies. The use of 3D printing in the aerospace industry is already transforming the way components are designed and built, with more anticipated changes on the horizon as major aircraft manufacturers and beyond discover innovative applications for 3D printing in aviation.
Applications of 3D Printing in Aerospace
Additive manufacturing and 3D printing technology will play an important role in the future of aerospace manufacturing. One could argue that these technologies are still in their infancy, but many applications for 3D printing in aerospace can already be observed, from prototyping to strategic consolidations.
Rapid Prototyping
3D printing is much faster than some traditional aerospace manufacturing techniques, which is incredibly valuable at the prototyping stage of product development and aircraft design. Fast prototyping, empowered by 3D printing technology, allows aerospace companies to iterate on new ideas more efficiently, so they can put new innovations into practice sooner and stay ahead of the competition.
Weight Reduction
Leveraging 3D printing in the aerospace industry allows aircraft manufacturers to experiment with more weight reduction strategies. 3D printing is compatible with a wide range of lightweight materials, so aerospace companies can manufacture lighter components. This practice, often called “lightweighting,” translates to greater fuel efficiency and aircraft range, both of which are valuable in the aerospace industry.
Customizable Tooling
3D printing in aviation has tooling benefits as well. 3D printing allows aircraft manufacturers to build custom tooling faster and often at a lower cost, making highly customized parts – and greater innovation – more accessible.
Consolidation of Parts
Utilizing 3D printing in the aerospace industry allows for the consolidation of multiple components during the aircraft manufacturing process. By 3D printing multiple connected parts at once, aerospace companies can reduce the time and costs associated with complex assemblies.
Benefits of 3D Printing in Aerospace
The benefits of aerospace 3D printing range from waste reduction to greater innovation, leading to reduced costs and greater efficiency.
Reduced Material Waste
3D printing and other aerospace additive manufacturing techniques produce far less scrap material than some traditional methods. Integrating 3D printing into the aerospace industry allows aircraft manufacturers to cut down on waste and use materials more efficiently. This is especially valuable in the event of a material shortage and precious resources must be used judiciously.
Improved Design Flexibility
3D printing is an extremely flexible manufacturing process, offering nearly unlimited customization opportunities. 3D printing in aerospace gives aerospace manufacturers the flexibility to experiment with innovative designs of new and existing components, so they can continuously improve their aircraft and stay competitive in a fierce market.
Cost Savings
Aerospace companies can realize multiple avenues of cost savings when they opt for 3D printing. As previously mentioned, 3D printing uses material more efficiently and cuts down on scrap waste, reducing material costs. 3D printing also gives aircraft manufacturers the ability to build multiple components of an assembly at once, eliminating the costs associated with multiple assembly steps. Lastly, because 3D-printed parts can be lighter, airlines and other aircraft operators may realize savings on an operational level due to increased fuel efficiency.
Challenges and Future Developments
3D printing in aviation has tremendous potential for innovation and advancement. However, since this technology is still in its early stages, there are some current and future challenges to be aware of.
Material Limitation
For many aerospace components, material durability is a top consideration for performance and longevity. Unfortunately, certain materials simply are not compatible with 3D printing – at least not at this stage. The potential of 3D printing in aerospace is somewhat limited by the existing portfolio of materials that are both durable enough for aerospace applications and compatible with 3D printing.
Quality Control
3D printing is not immune to quality changes. Variability issues such as warping, porosity, and surface irregularities can occur, which is problematic for components with tight tolerances. Unfortunately, traditional quality control methods are not always sufficient for 3D-printed components. This is largely because the additive manufacturing process creates both material and geometry simultaneously, forcing manufacturers to essentially conduct two types of quality control at the same time. New quality control methods for 3D printing are in development, but aerospace companies must navigate this challenge creatively in the meantime.
Certifications
Industry standards and certifications are critical to ensuring uniformity and quality in any industry. Some regulatory bodies are more stringent than others about granting certifications. Because 3D printing is a newer addition to the aerospace manufacturing world, there are no existing certifications for this manufacturing method. Developing appropriate standards will take time, and some manufacturers may need to change their methods in order to earn these certifications once they are announced.

A motor actuator valve, or motorized valve with an actuator, is a valve that opens and closes without human intervention thanks to a motorized power source. Motor actuator valves direct the flow of fluids and air in a wide range of applications, including aircraft and aerospace systems. This includes landing gear, engine control, fluid transfer, landing gear, and others.
A motorized valve with an actuator is considered an automated system, since the valve can be controlled by an input signal rather than a human operator.
Components of Motor Actuator Valves
There are three primary components of a motor actuator valve: the valve body, the actuator, and the actuator motor.
Valve Body
The valve body is the main component of a motor actuator valve. The valve body directs the flow of media within an aircraft system or aerospace fluid transfer assembly. The media differs depending on the application, but common media in aerospace contexts include water, hydraulic fluid, air, and combustible fuels. Motorized valve bodies are usually metal or plastic, depending on fluid exposures and other variables of the motor actuator valve’s service environment.
Actuator
The actuator converts power from the motor into mechanical motion, controlling the motorized valve.
Motor
The actuator motor powers the actuator. Usually, the motor and the actuator are connected by a gear or belt for power transfer.
Types & Applications of Actuator Valves Used in Aerospace
Motor actuators and motor actuator valves are among the most important components of any aircraft platform. Actuators trigger a wide range of essential aerospace functions, from simple valves to autopilot and landing gear operations. Motorized valves with actuators are extremely versatile, with multiple varieties found throughout many aircraft platforms.
Pneumatic Actuator Valve
A pneumatic actuator valve uses compressed air as a power source. Common applications for pneumatic actuator valves include high-cycle and rapid-cycle functions. Pneumatic actuation is an excellent choice for hazardous or explosive environments since there is no sparking. Pneumatic actuator valves are also well suited to high-temperature environments when paired with high-temperature seals.
Many pneumatic actuators use spring-return technology to move the valve into a “fail-safe” position if power or pneumatic pressure is lost for any reason, a desirable safety benefit for the aerospace industry.
Electric Actuator Valve
Electric actuator valves offer high flow precision for virtually any media used in aerospace applications, including nitrous oxide and combustible fuels. Electric actuators ensure extremely accurate positioning of valves and dampers, resulting in tight control of media flow. In addition to being highly dependable, electric actuator valves are smooth and quiet, which can be valuable in certain applications.
Many electric actuator valves offer a fail-in-place or “lock-up” feature. This means the valve freezes in place if the system loses power. Additionally, some electric actuator valves are fail-safe, like pneumatic actuator valves, though it should be noted that these are more expensive. Some companies may decide between fail-in-place and fail-safe electric actuators based on their budget and the application in question.
Hydraulic Actuator Valve
Hydraulic actuator valves are used to control the flow of water, air, fuel, hydraulic fluid, and other media that may be used in aerospace applications. Hydraulic actuator valves tend to be durable and powerful, making them a desirable option for high-force applications. Hydraulic actuator valves are also highly customizable, offering a wide range of configurations for different aerospace applications and aircraft systems.
Thermal Actuator Valve
Thermal actuator valves are controlled by a thermal actuator, which triggers mechanical motion, such as piston extension, in response to changes in temperature. Thermal actuator valves are highly precise and extremely accurate, a valuable asset in aerospace, where precision is often mission-critical. Thermal actuator valves provide constant modulation thanks to instant reactions to even minor changes in temperature, making them an excellent option for systems that require strict temperature control, such as fuel and oil temperature management and cabin environmental systems.

Their collaboration ensures a thorough examination of the issue. Effective root cause analysis training prepares each team member by clarifying their roles and responsibilities.
The process of root cause problem-solving typically involves a series of structured steps, as outlined below:
Define the Problem
After the RCA team is selected, the next step is defining the problem. This involves understanding the problem’s significance, impact, and size and identifying which product, process, or defect is at fault in the safety or reliability incident. It’s important to differentiate between the effect (outcome of a problem) and the cause (the origin of a problem). A clear and agreed-upon definition ensures everyone is aligned from the start.
Causal Factor Identification
Once the problem is defined, the next step is identifying the causal factors that contribute to the issue. Understanding all factors that contributed to the undesirable condition, situation, nonconformity, or failure enables a comprehensive review of the circumstances that led to the problem. These causal factors could include design flaws, procedural errors, human factors, or even environmental influences.
