There is a library of resources on and offline on how to replace car tires, as well as how to maintain them, and what to look out for when selecting new tires. But when it comes to information on aircraft tires, there aren’t as many resources or information readily available. It’s doubly important to know how to maintain your aircraft tires because the process can be lengthy and far more expensive than replacing car tires. Read on below for more information on aircraft tire maintenance and selecting new tires. 

Selecting New Tires

It’s important to always consult your Pilot's Operating Handbook (POH) before selecting new tires because your handbook will let you know the specific requirements on tire size, tire pressure, brand and model recommendations and ply rating. Doing otherwise could mean could unintended consequences for your aircraft and result in even more aircraft maintenance work than before.

After selecting new tires and inflating them, keep a lookout for your tires after you inflate them, as they tend to expand for up to 12 hours after being inflated. As tire volume increases, pressure decreases so be vigilant over newly inflated aircraft tires and reinflate them to the required pressure. Additionally, newly inflated tires should not be used until they’ve been more than 12 hours after inflation and have with their tire pressure checked. If your tire pressure is not properly maintained, this could potentially affect your tires’ performance and life span. 

Maintaining Your Tires

In the same way that you have to be vigilant of tire pressure and inflation when selecting new tires, you also have to be aware of these factors when maintaining your current tires. A change in temperature influences your tire pressure so it’s vital to check them daily and before flights using tire pressure gauge.

Along with keeping tabs on tire pressure and inflation, your tires should also be clean and free of oil, dirt, grease, or other contaminating agents. To clean your aircraft tires, it’s best to use denatured alcohol before spraying it down with soap and water.

An aircraft engine is a remarkably complex piece of machinery, with hundreds of moving parts that operate outside of the perception of the pilot’s senses. Most mechanical issues in an engine begin affecting the aircraft before they can be seen, heard, or felt. Fortunately, modern technological innovations have led to the creation of aircraft engine monitoring systems, arrays of sensors and digital computers that are designed to help the pilot gauge the health and status of their aircraft. These systems can determine what kinds of maintenance might be required for an aircraft’s engine, or help them determine if an engine is fit for operations. While typically used on commercial aircraft, they are popular for personal aircraft as well.

One major benefit of an engine monitoring system is that it allows the pilot to avoid costly repairs by catching a problem with the engine before it blossoms into something catastrophic. As with a car, small engine problems can be undetectable by human senses before something major occurs. A monitoring system, however, can pick up on these early warning signs, and dramatically increase the lifespan of an engine.          

Engine monitoring systems operate off of a set of small sensors placed within different regions of the aircraft’s engine, and are used to gather data on how the engine is functioning. This data includes measurements like temperature, vibration, fuel usage, and other metrics of an engine’s performance and health. The data these sensors gather is sent to the aircraft’s computer, and provides both real-time status updates throughout the aircraft’s flight, and analytics over time which can inform the pilot on when the time for repairs might be.

For example, the aviation sensors connected to the monitoring system will tell the pilot how much fuel is required to achieve a certain amount of power. The pilot later notices that this fuel intake is starting to increase over time, and are requiring more fuel to achieve their desired level of power than they used to. This data tells the pilot that their engine’s fuel efficiency is starting to decline, and they need to have maintenance performed to restore this efficiency.

Every part of an aircraft has a specific function, and with that function, specific maintenance requirements. The Federal Aviation Authority mandates regular maintenance and inspections of all aircraft, with some parts being required to be replaced after a certain number of hours in flight, no matter their current condition.

The airframe consists of the aircraft fuselage, wings, airframe, and undercarriage. It does not include the propulsion systems, which are complicated and important enough to warrant their own regulations. The airframe is subject to a significant amount of stress in flight, which can lead to cracks and fatigue in various areas of the airframe. Mechanics are trained to know where and how cracking will occur, and how to detect fatigue before cracks form. Corrosion can also be an issue as weather and extreme temperature changes during flight can cause rust and other forms of corrosion in seams and connections.

The engines, or power plant, provide thrust, hydraulic, and electric power the aircraft needs to fly. Taking the form of either lightweight piston engines or gas turbines, the power plant is made up of many different subsystems. Because it is so critical to the aircraft’s functioning, the FAA has many regulations requiring special inspections and routine maintenance. The hydraulic and pneumatic systems have their own set of regulations regarding inspection and maintenance as well.

In piston-driven aircraft, propellers convert the rotary motion from the engine into the force needed for aircraft to fly. Corrosion is a consistent issue for propellers, as it threatens the strength and integrity of the aviation propeller. Propeller blades can also become twisted or misaligned and suffer from nicks and cracks.

Instruments used in navigation must be constantly checked to ensure proper functioning. The altimeter, for instance, is used to determine the aircraft’s altitude, and must be removed from the aircraft, run through a bench test, and then reinstalled. At the same time, the pitot-static system that works in tandem with the altimeter must be tested as well to ensure there has been no leakage.             

The transponder, or transmitter-responder, is used to identify the aircraft on radar and assist in collision avoidance systems. If the transponder is out of alignment, it can cause incorrect altitude readouts, duplicate targets, or no targets at all.

The emergency locator transmitter, or ELT, is used to track an aircraft if it is in distress. The FAA requires the ELT be permanently attached to the aircraft. It can be automatic portable, which means it can be readily removable in case of an emergency, or automatically deployable, which means it automatically deploys after a crash. The FAA requires that the ELT’s battery is replaced before its expiration date and be inspected within 12 months after its last inspection. Batteries must be checked for corrosion and the whole unit needs to be activated per manufacturer instructions to ensure it works properly.

Chances are, you have probably used a fastener or a machine with fasteners in it within the past week. Used to make a connection between two components, fasteners are small pieces of hardware that come in very handy in a lot of different circumstances. The aerospace industry is particularly fond of fasteners as they form a rigid but temporary connection.

Unlike everyday circumstances, fasteners used in the aerospace industry are put through harsh conditions. Aircraft fly at high altitudes and are subject to vast pressure and temperature differences. The integrity of an aircraft is reliant upon the correct functioning of the fasteners. As the plane mechanisms heat up during system pre-heat, the various metals expand and contract, which in turn changes the physical relationships between metal components.  This is where the question of material of the fastener comes into play.

Corrosion and pressure are the two worst enemies of a fasteners. Aluminum is a popular material within the aerospace industry because it is relatively light for a metal. The problem with aluminum is that it doesn’t stand up to the task of fastener. Aluminum rivets can be used; however, they must be cold heat formed. While they may look the part, the fasteners are highly sensitive to temperatures above 250 degrees Fahrenheit. In terms of corrosion, aluminum doesn’t fair too well either.

Steel and steel alloys are aluminum’s stronger, heavier sibling. In aerospace applications, stainless steel is a popular choice of fastener material. The series of stainless steel is very important. Series 300 corrosion resistant stainless steel avoids the risk of corrosion but does not stand up too well against the excessive heat, in an aircraft’s landing gear for example. On the other hand, CRES series 400 steels have impressive heat resistance, but is subject to corrosion. The type and use of the aircraft will help determine which material to use. While they may not be a perfect material, steel fasteners are still an integral part of an aircraft.

When it comes to the ultimate material for fasteners, superalloys are the answers. For example, H-11 is a chromium tool steel alloy which is often used in the high stress areas of an aircraft such as the landing gears.

Regardless of the type of fastener you choose, there are strict guidelines in place that ensure the correct manufacturing of the fastener. The American Society of Mechanical Engineers (ASME) created a uniform manufacturing standard. Fasteners must be the same shape, material, and composition. If you are looking for fasteners within the military, you should also be aware of military standards and parts of military standard. Traceability is particularly important to the military. If a fastener is not up to military standard, it needs to be traced back to the manufacturer and the exact manufacturing line.

The Federal Aviation Administration (FAA) is an agency of the United States Department of Transportation; they are responsible for the oversight and regulation of aviation within the United States, as well as operation of the National Airspace System (NAS). The primary responsibility of the FAA is to ensure the safety of civil aviation. Their regulation responsibilities also encompass the following: development of aeronautics, operation of air traffic control and navigation systems for civil and military aircraft, regulation of U.S. commercial space transportation, and the development of programs to mitigate aircraft noise and other environmental effects of aviation. The FAA also controls the construction and operation of airports; adding to the list of complex responsibilities. 

The safe and efficient use of airspace is one of the administration’s main objectives. They accomplish this goal through a variety of integrated methods. Airport towers and air traffic control communications, air route traffic control sensors, flight service stations, the implementation air traffic rules, airspace use assignments, and a collection of other systems are used to regulate airspace.

The organization must also ensure all aircraft have the required clearances to fly. Similar to the requirements to obtain a driver’s license, but more complex in application, pilots must have the proper credentials to receive a pilot’s license. The FAA goes to great lengths to ensure the safety of others by guaranteeing all pilots have received the necessary licenses and certifications. They are also responsible for revoking/suspending licenses to those pilots who fail to meet the requirements and regulations.

The origins of the FAA began long before there were any federal organizations regulating air travel. With the introduction of commercial travel came the Air Mail Act of 1925, which was a means to regulate the growing production of commercial airliners. This legislation was quickly followed by the Air Commerce Act of 1926 which improved airline safety measures, enforced air traffic regulations, and established a pilot licensing system. The Bureau of Air Commerce was then established in 1934, implementing the first air traffic control centers. In 1958, the Federal Aviation Agency was created to combine the different aviation acts and regulations into one bureau. Finally, in 1967, the Federal Aviation Agency was renamed the Federal Aviation Administration. The name hasn’t been changed since, and the responsibilities of this administration have evolved over time.

Proper maintenance repair and overhaul procedures (MRO) contribute to the FAA’s main goal, “to provide the safest, most efficient aerospace system in the world.” The aircraft maintenance industry encompasses repair stations that perform specialized services such as plating, welding, or nondestructive testing procedures. In addition, other repair stations focus on fuel systems, carburetors, landing gear assemblies, electronics, etc. The repair maintenance industry is massive; it covers all segments of aircraft repair. An aircraft can fly safely and efficiently by following all the regulations of the FAA combined with proper upkeep from MROs.

The first time I saw an aircraft wiring diagram, I was astounded by the intricate design and complexity. No less notable, is the attention that must be paid to the configuration of every component within the wiring system, including electrical connectors. Each aspect of an aircraft, at one time or another, is exposed to sudden changes in temperature, humidity, and pressurization. As such, even aircraft connectors need to meet two crucial parameters—they need to be durable despite multiple stressors, and easy to replace under a time constraint. Original equipment (OEMs) of aircraft employ field replaceable units, carbon composites, and contact retention methods to meet these requirements.

A connector simply refers to a device attached to the end of an electrical cable that allows it to connect and disconnect from other components. Most electronics that are imperative to a successful flight cycle are housed in electrical boxes. A field replaceable unit (FRU) is favored in modern aircraft, as it is easy to replace and upgrade on the flight line, or at a repair station. Degraded boxes can quickly be swapped out for new ones in the event of degradation or damage.

Invariably, within aviation component design, lighter is better— more weight means more fuel, and more fuel means more money. It is no different with aircraft connectors, which is why many are now being made from carbon composites and engineered thermoplastics. These materials are designed with the strength of carbon fibers and lightweight attributes of plastics or resins. They are lighter than the metal connectors that have been used in the past and are designed to be non-flammable and resistant to corrosion.

In order to achieve maximum durability, and to ensure the electrical connectors are as fail-safe a possible, connectors utilize various contact retention methods. This configuration ensures that a cable will not be bumped out of place in turbulence or stress, and that it will not fall out of its connector. Electrical connectors also vary in shape depending on the types of cables involved and the required durability. The contact shape can be circular, rectangular, coaxial, and can act as splices or terminals.

A few examples of contact retention methods are on-interference locks and contact locks. On-interference locks refer to a contact and connector that are housed within a hard, rubber casing. This contact retention method is typically seen in wheel wells, or any connectors that are located on the outside of the airframe. Contact locks are located on the contact itself. They are a locking device that utilizes a spring attachment, which snaps into place when it encounters a ring within the connector.

Downed planes are costly planes. Aircraft on ground (AOG) situations cost money to buy replacement parts, to pay mechanics and engineers, to pay for inspections, to pay for terminal usage while the plane is downed, etc.; and none of that money is being made if the plane can’t fly, costing even more money. So, it makes sense that the MRO business would be booming, standing to profit tremendously from saving airliners from AOG situations. And, it would make even more sense that the aviation MRO services & industry is currently embroiled in fierce competition to innovate and evolve.

MRO stands for Maintenance, Repair, and Overhaul. It’s all the aircraft maintenance related activities that are required to ensure safety and airworthiness of aircraft and the individual parts. MROs are the natural product of huge gaps in the aviation industry formed by a lack of interest in the aftermarket from OEMs, original equipment manufacturers. While aircraft maintenance is the key to keeping aircraft and aircraft parts reliable and up to airworthiness standards, aviation OEMs tend to focus only on the development and production of aircraft parts and components, and not on what happens to the aircraft once it has been assembled and sold. But it wasn’t long before the rest of the aviation industry realized the value of MROs and the importance of growing and innovating it.

In order to make aircraft maintenance more efficient, many MROs are jumping on the IoT bandwagon. IoT, the Internet of Things, is the concept of connecting everything so that they can interact and exchange data automatically. It’s a beneficial concept for MROs because the combination of Big Data and IoT-enabled sensors could improve and streamline Condition-Based Maintenance (CBM) and provide better insights to enhance operations, reduce delays, allow preventative maintenance, and identify necessary repairs before they become disastrous.

There are many different advancements to MRO software and technology. Rudimentary artificial intelligence gave rise to autopilot systems that learn overtime and help pilots fly more safely and efficiently; augmented reality allows technical experts from thousands of miles away to more effectively communicate instructions to onsite operators, bridging the gap caused by a shortage of available technicians; and wearables and robotics are leading the way with innovative solutions for timely repairs. But, the most effective innovation of all is customizable MRO software.

MRO software is the brain behind the MRO process; it streamlines compliance procedures, maintenance, safety, etc. By utilizing MRO software, MRO operators can track MRO history and aggregate data for analysis on how to better maintain and repair their aircraft. But, not just any MRO software will do. Configurability, scale and magnitude factors, end-to-end solutions, etc.; a customizable MRO software is usually the better option because it allows MRO operators to develop insights and ideas into new ways to service their customers’ aircraft more efficiently and effectively.

Just as automobile companies lease cars, aircraft companies lease commercial aircraft. There are over 10,000 leased aircraft throughout the world, with Asia being the most popular region in terms of leases. Since 2008, the number of leased aircraft has gone up more than 50%, especially in Asia. The number of re-deliveries has been steadily increasing, and so has the number of repairs that need to be completed.

For example, Singapore and Hong Kong have been major repair hubs and leasing centers for the Asian and Pacific region for the last few years. The MRO capabilities and the demand for parts to repair aircraft has grown immensely. But, other countries like Malaysia and Indonesia are also rapidly developing in the MRO sector, driving demand for replacement parts and aftermarket spares as well.

Leasing companies and repair stations have a close relationship. Leasing companies need to consider the entire life cycle of the aircraft because they oversee operations and repairs for the aircraft’s entire lifetime. The more frequent routine maintenance a leased aircraft has, the better. Leased aircraft also do not allow for modifications to ensure that the aircraft remains in pristine condition for its entire life cycle. All aircraft that are leased must still comply with EASA and/or FAA standards, even during a transition period. This means that all proper documentation on the aircraft itself and the repairs must be kept up-to-date. All leasing contracts must be shared with MROs to confirm that no illegal modifications are being made to an aircraft, and to confirm that all proper documentation is provided.

Despite the strict regulations governing aviation, the end of a lease remains the biggest challenge for operators. Most internal cabin parts will need to be replaced by the end of the lease, but these parts have long lead times and are sometimes very hard to find. Therefore, leasing companies usually require leasers to give an eighteen-month notice before the end of a lease.

ASAP AM Spares, owned and operated by ASAP Semiconductor, should always be your first and only stop for all your repair parts and needs.  We’re a premier provider MRO services and replacement parts, whether new or obsolete. And we have a wide selection of parts to choose from and are available and ready to help 24/7x365. If you’re interested in a quote, email us at or call us at +1-702-919-1616.

Aviation, for the sake of safety, is a strictly regulated industry. As a result, every stage of an aircraft’s life is subject to endless procedures and protocols, especially the overhaul process. Over time, aircraft engines will need to be overhauled. Parts will need to be replaced, and the biggest concern during this process is safety. It is also important to maintain the value of the aircraft and engine, and the only way to ensure this is to overhaul the engine using the original manufacturer’s, or OEM’s, approved parts.

It is most ideal to replace your engine parts with parts manufactured by the OEM. This will guarantee that the new parts are an exact replacement for the old ones. The OEM uses the same machinery that was used to make the original part in order to make the replacement, ensuring that the replacement part will fit best in the engine. Also, using parts from the OEM takes less time and is also much easier to install.

Other manufacturers may partner with the OEM, and the OEM will have to approve the parts made to fit the engine. These parts are considered reliable in their fit and function. There are also third-party manufacturers who can make replacement parts. The government sets standards in order to ensure these third-party manufactured components are safe to use on an aircraft. Despite these strict regulations, these parts aren’t always guaranteed to be the right fit or finish for the engine.

Though third-party manufacturers may claim their parts are safer and better than the parts made by the OEM, it cannot be guaranteed since they are not fully aware of the original make and fit of the part. The smallest deviations can prove disastrous. So, instead, you should try finding OEM parts and aftermarket spares with us at ASAP AM Spares

Whether you’re driving a car or piloting a plane, to start the engine, all you really do is turn the ignition key or push the start button. That’s all it takes. But have you ever wondered how such a simple movement causes the spark plugs to fire and the engine to start? The answer is a magneto, a simple and highly reliable electrical generator.

Aircraft magnetos are engine driven electrical generators that use permanent magnets and coils to produce high voltages to fire the aircraft spark plugs. Because aviation runs on redundancy, in every aircraft piston engine, there are two independent ignition systems. There are two aircraft spark plugs per cylinder and a left and right aircraft magneto. The left and right magnetos each fire one plug per cylinder, allowing smoother and more complete combustion of the fuel mixture while still allowing for the redundant safety net in the event that one of the magnetos fail.

Aircraft Magnetos, as you would expect by the name, generate a voltage with the help of magnets. Each magneto is equipped with a permanent magnet on a rotor that spins in close proximity to a high-output coil of wire with two windings. The first winding is made with heavy copper wire and the second with finer wire. As the magnet spins, a magnetic flux is generated and passed through the first winding, creating a magnetic flux linkage. The number of magnetic flux linkages is not constant and generates a voltage as the number changes. However, this is not enough to fire the spark plugs. The second winding creates a voltage that is about 100 times stronger when the breaker points connected to the first winding open, collapsing the magnetic field and prompting a large change in magnetic flux linkages. The change in magnetic flux linkages creates a voltage that is amplified to 20,000 volts and released to ignite the spark plug by the second winding.
