Description
The AS4863D02 is a genuine Textron Aviation plug pipe supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It fits the Baron Series B55, E55, 58 or G58, Caravan or Grand Caravan EX, Citation Excel, XLS, XLS+, XLS Gen 2, and Skyhawk. It carries an export classification of ECCN 9A991.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the AS4863D02 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.
Across the Beechcraft Baron, Cessna Caravan, Cessna Citation, and Cessna Skyhawk fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
Supplied as a defined part in the manufacturer's catalog, its exact role is set by the aircraft's parts and maintenance data. 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.
These aircraft are built by Textron Aviation, which unites Cessna (founded 1927) and Beechcraft (founded 1932) under one Wichita, Kansas company since 2014. The Baron — a twin-engine member of Beechcraft's piston line introduced in 1961 — shares much of its structure and hardware with the Bonanza.
