Description
The S3100-138 is a genuine Textron Aviation master control 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 9A991.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the S3100-138 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Because the Cessna Skyhawk and Skylane aircraft share extensive structure and hardware, a single part like this is often common across several variants.
As a factory-supplied item for a type-certificated aircraft, this part is defined by the manufacturer's specification and applicability data. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
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.
Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections.
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.
