VANITY INSTALLATION

The 101-531178-21 is a genuine Textron Aviation vanity installation — a factory assembly of several components supplied together as one serviceable unit. It is applicable to the Super King Air 350. As an original-equipment (OEM) part supplied directly by Textron Aviation, the 101-531178-21 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 Beechcraft King Air aircraft, reflecting how much structure and hardware these models have in common. This is a cataloged factory part whose form, fit, and function are established by the manufacturer's approved data. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation. 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. Built by Beechcraft — the Wichita, Kansas manufacturer founded in 1932 and part of Textron Aviation since 2014 — this part carries a name long associated with rugged, capable aircraft. With more than 7,700 delivered since 1964, the King Air is the most popular business turboprop family ever produced.
