VENT LINE

The 0516016-21 is a genuine Textron Aviation vent line that typically routes a fluid, air, or electrical run through the aircraft. It fits the Skyhawk. It carries an export classification of ECCN 9A991, weighs 0.09 pounds, and measures 19.05 (L) x 4.95 (W) x 0.95 (H) Inches. Because the 0516016-21 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 Skyhawk fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. Because it handles pressurized fluid or air, a component like this is specified precisely for its service — the right part keeps the system sound. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. 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 Cessna 172 Skyhawk is the most-produced aircraft in history, with more than 44,000 built since 1956, and remains in production under Textron Aviation.
