The Essential Tools Every Aircraft Mechanic Should Have in Their Toolbox

Aircraft mechanics play a crucial role in maintaining the safety and airworthiness of aircraft. From routine maintenance to critical repairs and instrument upgrades, a good aircraft mechanic is key to keeping your aircraft in the sky. Their expertise and skills are impressive on their own, but every good aircraft mechanic needs a comprehensive set of tools to practice their trade. Having the right tools on hand will enable them to perform a wide range of tasks efficiently and effectively. Fortunately, the experts at SkyGeek know what it takes to work on an aircraft and have put together a list of 15 types of essential aircraft maintenance tools that every aircraft mechanic should have in their toolbox. From basic hand tools to more special tools in aviation, these tools are vital for conducting inspections, performing repairs and completing routine maintenance procedures on various aircraft systems.

In an industry where precision and reliability are non-negotiable, having access to the right tools not only enhances performance but also supports long-term operational safety and compliance with aviation regulations.

Basic Hand Tools

Every aircraft mechanic needs some common mechanic tools available to help them work. Hand tools are the heavy hitters of the mechanical world, so it's important to invest in tools that are durable, comfortable to use and able to get the job done. Here are a few must-have mechanic tools:

1. Aviation-Specific Toolbox: While not technically a tool, a sturdy and well-organized toolbox is the foundation of every aircraft mechanic's toolkit. Look for one specifically designed for aviation tools, with compartments and dividers to keep tools organized and easily accessible. You'll want plenty of compartments and dividers so you can keep things organized and within reach. A rolling toolbox is a great idea if you do a lot of field work. In addition, consider adding modular tool trays or foam organizers that provide a visual reference for each tool's placement. This organization trick reduces misplacement and improves efficiency during maintenance tasks.
2. Screwdrivers: A set of high-quality screwdrivers, including both flat-head and Philips-head screwdrivers, is essential for removing and tightening screws and fasteners of different sizes in airplane tools and components. Look for a screwdriver with solid construction and a durable, comfortable handle. Padded handles can degrade and react with certain aviation chemicals, so opt for hard plastic instead. Precision screwdrivers are also useful when working on delicate avionics or control panel components. A magnetized tip can provide better control in tight spaces.
3. Pliers: Various types of pliers, such as needle-nose pliers, slip-joint pliers and locking pliers (commonly known as Vise-Grips) are indispensable for gripping, bending and manipulating objects. Pliers can be used to twist, bend and shape wires, cables and small parts. Make sure to get a complete set of pliers in various sizes so you always have the right tool for the job. Don't overlook specialty pliers like safety wire pliers and duckbill pliers-these often come in handy during intricate jobs.
4. Wrenches: A range of wrenches, including open-end wrenches, box-end wrenches and adjustable wrenches are necessary for tightening and loosening nuts, bolts and fittings throughout the aircraft. Wrenches come in various styles, but the simpler the better and plain metal is all you need for a reliable, easy to grip tool. Universal joint sockets and deep sockets are excellent additions that provide even greater reach and versatility when accessing hard-to-reach bolts.
   
   

   

5. Socket Set: A comprehensive socket set with both metric and standard sizes is essential, along with extensions and ratchets. A good socket set with a complete range of sizes is vital for accessing and working on fasteners in confined spaces. Choose a socket set with a durable plastic case to keep your tools organized.
6. Aviation-Specific Torque Wrench: Torque wrenches are critical for tightening fasteners to precise torque specifications. Ensure you have an aviation-specific torque wrench with a wide range of torque settings suitable for aircraft components. Torque wrenches for aviation applications are slightly different than other torque wrenches, so make sure you have the right kind.

Measuring and Inspection Tools

Measuring and inspecting is a normal part of aviation mechanic tools usage, and while a visual inspection is always a good idea, a quick glance might not be enough to spot certain issues. Make sure you're ready to take a deeper look at your aircraft by ordering the right measuring and inspection tools from SkyGeek.

1. Aviation-Specific Ruler and Tape Measure: Accurate measurements are essential in aircraft maintenance, which is why you should invest in an aviation-specific ruler and a tape measure. Make sure your ruler and tape measure tools have both metric and standard units for measuring distances, clearances and dimensions. Laser measuring tools are also becoming increasingly common in aviation workspaces due to their quick-read capabilities and enhanced accuracy.
   
   

   

2. Digital Caliper: A digital caliper allows precise measurements of small parts and clearances, especially in critical areas such as engine components and control systems. You'll use your calipers to measure all kinds of parts and to make sure gaps and fittings are correct, so invest in a caliper that's reliable and can hold its calibration.
3. Feeler Gauge: The feeler gauge tool is used to measure gaps and clearances between components, ensuring proper tolerances are maintained. A set of feeler gauges with varying thicknesses is essential for precise measurements. Maintaining the correct gaps and clearances are essential to your aircraft's performance.
4. Aviation-Specific Inspection Mirror: There are parts of the aircraft you won't be able to see easily. An inspection mirror with an extendable handle and adjustable angles is invaluable for inspecting hard-to-reach areas, such as behind panels or in tight engine compartments. A good inspection mirror eliminates the need to remove components to inspect behind them, minimizing the risk of damage.
5. Borescope: A borescope is a specialized tool that enables visual inspections of internal components and systems. It consists of a flexible fiber optic cable with a camera attached, allowing mechanics to see inside areas that are otherwise inaccessible. A borescope with a good camera will deliver a clear picture for easy inspections and a high degree of confidence. Many modern borescopes include video capture and wireless display functions, making it easier to record and analyze inspections during complex procedures.

Specialized Tools and Equipment

While basic tools are important to have on hand, sometimes more special tools in aviation are needed. Some specialized tools and equipment that are good to have on hand include:

1. Safety Wire Twisting Pliers: Safety wire is commonly used to secure fasteners and to prevent loosening due to vibration, but safety wire can be incredibly difficult to twist by hand, especially if it's in a hard-to-reach area. Safety wire twisting pliers make the task easier by twisting the wire securely and neatly with less strain on the hands.
2. Rivet Gun: Aircraft often use rivets for joining structures and panels, but those rivets can become loose or break over time. A quality rivet gun, along with an assortment of rivets and rivet sets, is necessary for installing and removing rivets during repairs and inspections, This is a staple in your aircraft mechanic tools list.
3. Electrical Multimeter: An electrical multimeter is essential for diagnosing and troubleshooting electrical systems and circuits. It helps measure voltage, current and resistance, ensuring proper functioning of electrical components. For any mechanic attempting an electrical repair, a multimeter should be considered essential equipment.
4. Aviation-Specific Crimping Tool: Crimping connectors and terminals is a common task in aircraft electrical systems. An aviation-specific crimping tool can make it easy to create connections and to ensure that connectors are securely attached to existing wiring. For enhanced precision, use a ratcheting crimping tool that guarantees consistent pressure and reduces user fatigue.
