SEAL

The 0509070-4 is a genuine Textron Aviation seal used to keep a joint or pass-through tight. It fits the Skyhawk. It carries an export classification of ECCN 9A991, weighs 0.29 pounds, and measures 15.5 (L) x 3.7 (W) x 0.35 (H) Inches. Because the 0509070-4 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. Sealing components are sized and compounded for the fluids, temperatures, and pressures they contain, so the exact specified part maintains a tight joint. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. 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. Cessna traces to the company Clyde Cessna founded in Wichita, Kansas in 1927; Textron Inc. acquired it in 1992, and since 2014 it has anchored Textron Aviation alongside Beechcraft and Hawker. 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.
