Description
The CA3559 is a genuine Textron Aviation filter air — a filtration element for a fluid or air system. It fits the Skyhawk. It carries an export classification of ECCN 9A991.
Because the CA3559 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 Skyhawk aircraft, reflecting how much structure and hardware these models have in common.
Because it handles pressurized fluid or air, a component like this is specified precisely for its service — the right part keeps the system sound. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
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.
