Description
The S3330-1 is a genuine Textron Aviation gyro direc supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is applicable to the Skyhawk. It carries an export classification of ECCN 7A994.
Because the S3330-1 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.
This is a cataloged factory part whose form, fit, and function are established by the manufacturer's approved data. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
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.
