NUT

It carries an export classification of ECCN 9A991, weighs 0.01 lbs, and measures 0.57 (L) x 0.50 (W) x 0.33 (H) in. Because the MS21225-5 is an original-equipment (OEM) part sourced directly from Textron Aviation, it matches the exact specification and placement called out in the aircraft's type design and maintenance data — assurance a generic substitute cannot offer. Parts like this are shared across the Cessna Citation, Beechcraft Premier, and Cessna SkyCourier aircraft, reflecting how much structure and hardware these models have in common. Strength grade and finish define aircraft hardware, so matching the specified part keeps the joint as designed. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. These aircraft are built by Textron Aviation, which unites Cessna (founded 1927) and Beechcraft (founded 1932) under one Wichita, Kansas company since 2014. The Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
