BUS BAR ASSEMBLY

The 390-322300-0001 is a genuine Textron Aviation bus bar assembly supplied as a built-up assembly of several components in a single installable unit. It is fitted to the Premier Model 390. As an original-equipment (OEM) part supplied directly by Textron Aviation, the 390-322300-0001 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 Beechcraft Premier aircraft share extensive structure and hardware, a single part like this is often common across several variants. Electrical and electronic components are defined by exact ratings and characteristics, so the specified part keeps the circuit performing as engineered. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration. Using the factory part number preserves configuration control, so the airframe stays consistent with its approved type design and the work is straightforward to sign off at inspection. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. Beechcraft, founded in Wichita, Kansas in 1932, joined Cessna and Hawker under Textron Aviation in 2014, which today supports the worldwide Beechcraft fleet with genuine factory parts. The Beechcraft Premier I was a clean-sheet, composite-fuselage light jet — the first jet Beechcraft designed in-house — supported today through Textron Aviation.
