National Aerospace Standards: Securing the Way Home
November 7, 2019
No matter how or where you’re going, the vehicle you ride in will almost certainly be made up of standardized parts that get you to your destination. As we celebrate World Standards Day, we reflect on the importance of standards and the immense impact they have on our lives.
When performance and reliability are essential – which is practically always when it comes to aerospace and defense – standards are used to meet the requirements of high-strength applications. At AIA, the National Aerospace Standards organization provides our industry with these standards. They relate to parts in all shapes and size, and each one serves a vital purpose. There’s probably no better representation of this than NAS1149 – an ordinary washer with an extraordinary impact.
NAS1149 is one of AIA’s most popular part standards and has seen a wide variety of uses throughout our industry. Washers are one of the most common engineering components, ensuring a snug and secure fit for any screw or bolt. Published in 1990, NAS1149 can be found on many famous aircraft, including the V-22 Osprey used by the U.S. Armed Forces. While incredibly simple in both role and use, it is that very simplicity which makes this washer such a vital component.
Without standards like NAS1149, the world would be quite different. They allow repairs to be safely and easily made without concern for deviations in design. They also encourage healthy competition, allowing airlines and other aircraft owners to competitively source parts and keep costs low. In military service, NAS1149’s mission is even more important, keeping our aircraft in the skies and ensuring pilots can conduct their missions and return home.
So for World Standards Day, whether you’re flying to an exotic destination or driving home from work, take a minute to think of the small nuts, bolts, and screws keeping you secure and the standards that make all our travels possible.
