GDU-1044B DISPLAY UNIT

The S3100-558 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 applicable to the Skyhawk and Skylane. It carries an export classification of ECCN 7A994. As an original-equipment (OEM) part supplied directly by Textron Aviation, the S3100-558 is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs. Parts like this are shared across the Cessna Skyhawk and Skylane aircraft, reflecting how much structure and hardware these models have in common. Supplied as a defined part in the manufacturer's catalog, its exact role is set by the aircraft's parts and maintenance data. 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. Because aircraft parts are governed by strict airworthiness and traceability rules, fitting the OEM part rather than an unapproved equivalent keeps the installation eligible and the aircraft's records clean. 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.
