Description
The S3100-620 is a genuine Textron Aviation gdu 1044b display unit supplied as a built-up assembly of several components in a single installable unit. It is fitted to the Skyhawk and Skylane.
Because the S3100-620 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.
Because the Cessna Skyhawk and Skylane aircraft share extensive structure and hardware, a single part like this is often common across several variants.
This is a cataloged factory part whose form, fit, and function are established by the manufacturer's approved data. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
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.
