BALL ASSY

The 1504-128-4 is a genuine Textron Aviation ball assembly — a factory assembly of several components supplied together as one serviceable unit. It is fitted to the Skyhawk and Skylane. It carries an export classification of ECCN 9A991, weighs 0.01 pounds, and measures 0.8 (L) x 0.75 (W) x 0.75 (H) Inches. As an original-equipment (OEM) part supplied directly by Textron Aviation, the 1504-128-4 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. Because the Cessna Skyhawk and Skylane aircraft share extensive structure and hardware, a single part like this is often common across several variants. Supplied as a defined part in the manufacturer's catalog, its exact role is set by the aircraft's parts and maintenance data. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value. 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. With over 44,000 built, the Cessna Skyhawk is the best-selling aircraft ever made and is still produced today.
