Those working in the aviation manufacturing industry are likely familiar with essential tools such as hand cutting tools. While some of these tools can be utilized in other fields- including the auto and marine industry- they are significant to aviation mechanics and manufacturers. Below you’ll find a brief outline and description of the tools that aircraft manufacturers tend to use.

Files: Because files are so commonplace across several different industries, these tools are often overlooked. However, they play an essential role in the manufacturing of aviation parts. They help shape through cutting and abrasion. Files come in all different shapes and sizes ranging from as small as 3 inches to 8 inches. The files has four main distinct properties, which are length, contour, form, and teeth.

Die GrinderA die grinder is a tool aircraft manufacturers use to administer to mounted cutoff wheels, rotary files, sanding disks or high speeds. This category of grinders (electric) are typically powered by compressed air. Pneumatic die grinders run at 12,000 to 20,000 revolutions per minute (rpm) with the rotational speed controlled by the operator who uses a hand or foot-operated throttle to vary the volume of compressed air.

Burring ToolThis type of tool is used to remove a burr from an edge of a sheet or to deburr a hole. Deburring is an extremely important stage in an airplane building process. Anytime you cut an edge or a hole or you drill a hole on the aircraft metal part, you'll need to deburr it. In other words, you'll need to knock the sharp edges off – remove punch marks, polish edges and remove burrs caused by cut-off wheels or drills, as smooth edges will reduce the risk of stress cracking. The surface should be smooth, so you don’t cut your finger when pressing and running it along the metal edges.

Aircraft maintenance is imperative in ensuring airworthiness and the safety of every passenger, crew member, and piece of cargo. Proper maintenance requires more than just training and experience, it also requires the proper tools. Here are six of the most important tools used in aircraft maintenance.

Speed Handle

Sophisticated aircraft engines can have thousands of screws. Since aircraft mechanics are often inundated with work, they don’t have the luxury of focusing on one aircraft, fixing it, and moving to the next one. Instead, they often must attend to multiple tasks at once. The speed handle, a long screw, allows technicians to quickly remove screws while simultaneously juggling other repairs.

Torque Wrench

In most cases, the screws and fasteners on a helicopter rotor need to be installed with a very specific tightness or torque. Despite this, most wrenches or spanners that work well for tightening nuts and bolts are not as effective for screws. The most trustworthy method of tightening screws is with a calibrated torque wrench. Torque wrenches are manufactured to be set at varying torque amounts, making them very helpful in aircraft maintenance.

Vibration Meter

As you might guess, the vibration meter’s role is to measure the vibration levels in an aircraft. Vibration analysis is important in ensuring the safety of an aircraft during flight. If there is excessive vibration, there is likely a greater issue at hand. Vibration meters measure vibrations in kilograms and denote the maximum vibration a given aircraft can withstand. They help a pilot realize the significance of vibration, allowing them to take the proper precautions to maintain the integrity of the aircraft.

Pliers

Most aircraft have safety wires to supplement fasteners and ensure that they are working properly and will noy loosen. Pliers are used to hold tie these wires together in strong braids and prevent them from loosening.

Metal Working Tools

All the major components of an aircraft are constructed of metal. Because of this, any significant repair necessitates the use of proper metal working tools. These tools are most commonly used to fasten, bend, and cut metals. Tools you might use on your aircraft include rivet guns and drills, used to hold important structures together.

Mirrors

Very simply, mechanics can’t always easily see critical parts of the aircraft that need to be inspected. Mirrors can give mechanics a line of sight without having to disassemble huge engine components.

The fuel system is an extremely integral part of aircraft as it helps to deliver fuel to engine, creating power and propulsion that allows for flight. Basic aircraft often have a single fuel tank that is gravity fed and a fuel line that connects the tank to the aircraft engine. Modern aircraft, however, are more complex and may include multiple fuel tanks with plumbing, valves, and internal fuel pumps. No matter the amount of tanks and components, an aircraft fuel system always consists of an aircraft fuel system and an engine fuel system. With the varying types that exist in differing types of aircraft, how do their fuel systems function?

Along with varying types of aircraft fuel systems, there are also different types of fuel depending on the type of aircraft and application. Military grade fuel will often be denoted by the letters “JP” before their name, such as JP-8 which is widely used by the US military. Standard commercial airliners use A, A-1, and B fuel, which can also be used by military aircraft as well when JP fuel is not available.

Fuel tanks of aircraft are designed in varying shapes, size, construction, and location depending on the aircraft type. Nevertheless, most tanks include access panels for repair, pumps, strainers, quantity indicators, valves, vents, and drains. Fuel begins from the tank and is piped through fuel lines to the control valve, often utilizing gravity feeding or pump feed systems. Valves are helpful for crews as they can be shut off to prevent fuel, as well as enable control of flow to decide which tanks feed the engine. By controlling which tank feeds the engine, fuel load can be balanced and help the aircraft to avoid unbalanced weight, which may cause banking.

As fuel leaves the tank, air is allowed into the tank to replace the fuel that has been burned, preventing fuel starvation. Fuel lines take fuel slightly above the bottom of the tank, ensuring that contaminates such as dirt do not enter the engine. The fuel runs through conductive pipes that prevent or dissipate static charge buildup. Fuel then passes through the gascolator which collects contaminates in the fuel, and then to a fine filter before it enters the carburetor. The carburetor is a device which mixes fuel with air for the internal combustion engines. The mixture is finally pushed into the aircraft engine in which the fuel is ignited for the turbines to extract power and create propulsion.

Aircraft maintenance checks are periodic inspections that every commercial and civil aircraft must go through after a certain number of flying hours or length of time of use. Military aircraft go through different sets of checks, but their maintenance programs are just as stringent.

The aviation industry is extremely regulated, and commercial operators must comply with the continuous inspection programs established by the aviation authorities of different countries. The Federal Aviation Administration of the United States, Transport Canada, and the European Aviation Safety Agency are several of these regulators. Each operator must establish a CAMP, or Continuous Airworthiness Maintenance Program, which includes routine and detailed inspections of air assets.

Commercial operators, airworthiness authorities, and MRO (maintenance, repair, overhaul) providers call detailed inspections “checks.” A and B checks are relatively minor, while C and D checks are more exhaustive. Aircraft operators can conduct lighter checks at their own facilities, but heavier checks must be performed by a certified MRO company.

A checks are performed every 400-600 flight hours, or 200-300 cycles (a cycle is one takeoff and landing). A checks last roughly 50-70 man hours and require an aircraft to remain on the ground for at least ten hours depending on the condition of the aircraft.

B checks, meanwhile, are performed every six to eight months and require 160-180 man-hours, depending on the aircraft type and condition. These checks often take one to three days.

C checks are performed every 20-24 months, or after a number of aircraft manufacturer defined flight hours. C checks are more extensive than A and B checks, and involve inspecting a large number of components. A C check will require an aircraft to stay in the maintenance site for at least two weeks, and will take up to 6,000 man-hours of work to finish.

D checks are the most comprehensive, invasive, and time-consuming check. Also called a heavy maintenance visit, D checks are performed roughly every six to ten years, and  go as far as taking the entire aircraft apart for inspection and repair. A D check can take up to two months, require 50,000 man hours of work, and cost one million dollars to complete. Most operators will choose to retire their aircraft after two or three D checks rather than go through another, as the cost of repair will actually exceed the value of the aircraft.

Whether you are just entering the world of aviation or are a seasoned veteran in the industry, there is an entire library of terminology that you must be familiar with in order to succeed in this field. For those already acquainted with the industry, consider this an important review. And for those fledgling pilots, pilot mechanics and the like: get your study hat on and get to work.

Index of Terms

Absolute Altitude: height distance above ground level

Airline Transport Pilot (ATP): ATP refers to the pilot certificate necessary for anyone wanting to work for major and commuter airlines, as well as regional carriers. This certificate is meant to distinguish pilots with the highest level of experience. In order to obtain this certificate, you would need to complete a flight assessment and written test and would also need to have a minimum of 1500 hours of flight experience.

Airfoil: The basic structure of a wing, this refers to a surface with a carved top and a flat bottom

Axes of Flight: Refers to the three axis of flights which are 1) pitch, 2) yaw, and 3) roll. See definitions below.

Bernoulli Principle: A very important fundamental truth in flight, this principle was published in 1738 by Swiss scientist Daniel Bernoulli. In his book Hydrodynamica, Bernoulli explains how lift can be generated via air pressure over an airfoil. The curved top of the airfoil cuts the natural flow of air, increasing air pressure below the wing and lowering pressure above. This, in turn causes the aircraft to lift.

Federal Aviation Administration (FAA): the official United States national authority responsible for regulating all aspects of aviation in the US including air traffic management, construction and operation of airports, operation and construction of US airports, etc.

Federal Aviation Regulation (FAR): the official rules outlined by the FAA which regulate all aviation activities in the US including flights, pilot training, drone operations etc.

International Air Transport Association (IATA): a trade association that consists of 290 of the world’s airlines, with primary major carriers from 117 countries

Knots: refers to nautical miles per hour (100 knots is equivalent to flying 115 MPH)

Nautical Mile: used to measure aviation distance (one nautical mile is equal to 1.15 standard U.S. miles)

Pitch: one of the three axis of flights, refers to the axis which is perpendicular to the yaw axis. It is also parallel to the wing plane and located towards the right wing tip

Roll: one of the three axis of flights, perpendicular to the pitch and yaw axis, directed towards nose of aircraft

Slipstream: stream of air that is created by either a rotor or generator

Transponder: A device for transmitting and responding details on an aircraft’s position and altitude. Transponders are used to provide alerts of aircraft to air traffic controllers; useful for averting on air collisions

Yaw: one of the three axis of flights that is directed toward the bottom of the aircraft, and perpendicular to the plane of the wing with its origin at the center of gravity

These are just a few selections of important aviation terms but there are many more terms that are needed to understand aviation. You can trust that experts in the industry, such as the professionals at ASAP Aviation Unlimited, will understand these terms and know how they apply in the field.
