TUBE ASSY

The 6617350-18 is a genuine Textron Aviation tube assembly of a type generally used to route fluid, air, or wiring through the airframe. It is fitted to the Citation Excel, XLS, XLS+, XLS Gen 2. It carries an export classification of ECCN 9A991. Because the 6617350-18 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. Across the Cessna Citation fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. Fluid- and air-system components are rated for specific pressures, media, and fittings, so the correct part is essential to a safe, leak-free system. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. The factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk. The Cessna name is among the most recognized in aviation — founded in Wichita, Kansas in 1927 and part of Textron since 1992, today a cornerstone of Textron Aviation. The Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
