Aircraft Hand Tools Every Aircraft Technician Should Know

Aircraft inspection and maintenance is one of the most important facets of the aviation industry, ensuring the aircraft and related systems remain operational, efficient, and have long service lives. While there are a plethora of new and advanced technologies and aircraft maintenance equipment that are making inspection and maintenance procedures quicker and easier, a technician may always rely on their assortment of aircraft hand tools to get the job done. In this article, we will discuss the primary aircraft hand tools that every aircraft technician should be familiar with.

Alongside many sectors of the aerospace industry, aircraft maintenance equipment is quickly advancing. While newer tools and equipment open up new possibilities of service, the traditional tools of an aircraft technician is always a set that can be relied on for correct servicing if needed. As equipment and systems advanced, certain tools may be customized to fit a very specific task or need. If a tool is used incorrectly or in the wrong area, it can cause damages or danger that risk the aircraft’s integrity. By using the correct tools that they are familiar with in such cases, proper maintenance can be assured by the technician.

A torque wrench is a tool that is used to tighten fasteners, and they typically come with a socket wrench face. With a torque wrench, an aircraft technician can quickly tighten screws, nuts, and bolts to ensure that there is an optimal amount of torque applied to match the needs of a specific application. In the realm of aviation and aerospace, correct torque is paramount for performance, safety, and reliability. With the correct calibration, torque wrenches can provide reliability over spanners, and let a technician quickly tighten fasteners and components.

A vibration meter is one of the most important aircraft hand tools as it allows for the technician to check whether an aircraft would be safe to fly. Within critical areas such as the engine, high amounts of vibration can lead to damaged components, and eventually engine failure. With a vibration meter, the technician can check the maximum amount of vibration that an aircraft can withstand. With these measurements, the technician can then make changes as necessary to ensure that the aircraft is safe while subject to extreme conditions during flight operations.

Metal working tools are useful aircraft maintenance equipment for performing mechanical repair across the metal frames and structures of the aircraft. Such aircraft hand tools may be used for fastening, bending, and cutting metals, and common tool types include drills and rivet guns. With metal working tools, the technician can fasten structures, cut metals, and perform other operations as necessary for the aircraft.

Despite what some may assume, mirrors are actually a very useful tool for aircraft technicians. With a mirror, the technician may be able to see a component or critical area that they would normally be unable to see if it is in a more unreachable area. With a mirror, the technician can service an area or inspect it without having to dismantle components.
