Description
The NAS446-4-1 is a genuine Textron Aviation nut — a fastening or retaining hardware item used in the airframe. It fits the Baron Series B55, E55, 58 or G58 and Bonanza 36. It carries an export classification of ECCN EAR99.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the NAS446-4-1 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Parts like this are shared across the Beechcraft Baron and Bonanza aircraft, reflecting how much structure and hardware these models have in common.
Strength grade and finish define aircraft hardware, so matching the specified part keeps the joint as designed. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. 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.
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. The Beechcraft Baron, introduced in 1961 as a twin-engine development of the Bonanza, carried Beechcraft's reputation for solid handling into a capable light twin.
