Aircraft maintenance and repair practices are essential aspects of ensuring the safety and efficiency of aircraft and their related systems, regularly being carried out on a scheduled basis and as necessary. To support these activities, having dependable access to a wide range of parts is a must, and shopping by NSN listing information better guarantees that one secures exact needs with ease. This blog will explore some of the most common part types needed for aircraft maintenance and repair, highlighting the importance of sourcing these parts with NSN listing information through reliable channels.

To minimize downtime and get aircraft back up and running, maintenance personnel and repair stations heavily depend on reliable suppliers, supply-chains, and purchasing options to secure the necessary parts for their operations. One easy way to streamline the search and procurement process is to shop for parts by National Stock Number (NSN) data. This system, accepted by all NATO countries, assigns unique 9-digit codes to material items of supply, simplifying identification, management, and trade across the globe. Each code also is also made up of segments that contain various useful information like the item’s general application. As such, using the NSN system to procure aircraft maintenance and repair parts allows one to avoid much of the initial complexity of procurement.

When it comes to the most commonly used NSN part types used during maintenance and repair, a fundamental group to be familiar with is consumables. These include items such as fasteners, seals, gaskets, and adhesives, all of which have finite life spans or uses that necessitate regular replacement. Fasteners, including bolts, nuts, and screws, are subject to wear and tear over time with continued use, and they must be replaced as necessary to uphold the integrity of aircraft structures and assemblies. Seals and gaskets, meanwhile, are vital for preventing leaks in fuel, hydraulic, and pneumatic systems, as well as maintaining pressure and deterring contamination. Given the high pressure and extreme conditions these systems generally operate under, it is crucial to use high-quality seals and gaskets with adherence to manufacturer specifications on replacement intervals. Lastly, adhesives are commonly relied on in aircraft maintenance procedures for bonding materials and components, providing additional strength and stability to final assemblies.

Another essential group of NSN parts that is important for maintenance and repair is electrical components. This includes items like connectors, relays, switches, and wiring harnesses that are integral to electrical systems ranging from cabin lighting to avionics. Like consumables, electrical parts are subject to degradation over time, resulting from a mix of environmental conditions, mechanical wear, deformation, corrosion, and other forces. As many critical flight systems and passenger amenities depend on electrical parts, having a source of everything from connectors to switches is highly advantageous. This is increasingly important as aircraft continue to feature more electrical systems and equipment over time, raising the total amount of electronics that need to be managed.
