Description
The 390-322246-0029 is a genuine Textron Aviation panel assembly circuit break that typically serves a role in an avionics or electrical circuit. It is fitted to the Premier Model 390.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the 390-322246-0029 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.
Ratings, tolerances, and interfaces are what define an electrical part; matching the specified item keeps the system working as certified. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
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.
